The plasticizing process of raw materials in the single-screw Plastic pellet machine

According to the requirement of the formulation for plastic products, through inlet hopper sent evenly send raw materials to the chamber of the Plastic pellet machine. As the screw rotates, the material is propelled by the thread to the front of the chamber.

In the front of the chamber, there is resistance of screen pack, shunt plate and molding mould, besides, with the gap between threads shrinking, under the gradually shallower depth of thread material combined with heating generated by the chamber at the same time, material pushed forward will be squeezed, sheared, heated and stirred , and coupled with force generated by friction between inner chamber walls and the thread surface, a certain quantity of heat created making the temperature of raw materials rise when it is pushed forward.

During this process, its physical state is gradually transformed from glass state to high elastic state, and finally become a sticky flow, thus achieve the full plasticizing effect. The screw rotates steadily and continuously, can extrude the uniformly molten material from the molding die out to finish a plastic product of a certain shape. Then through cooling and shaping, the finish extruded products are processed.

Plastic granulator equipment

Our company is a manufacturer of plastic granulators. Our company has won high recognition from our customers with its stable and reliable quality, reasonable and reasonable price and professional and thoughtful service. The following plastic granulator manufacturers introduce you to the equipment of the plastic granulator:

  Auxiliary equipment

The auxiliary machine of the plastic granulating unit mainly includes a pay-off device, a straightening device, a preheating device, a cooling device, a traction device, a metering device, a spark testing machine, and a wire take-up device. The use of the extrusion unit is different for its optional auxiliary equipment. For example, there are also cutters, blowers, printing devices, and the like.

Straightening device: The most common type of plastic extrusion waste type is an eccentricity, and the bending of various types of wire core is one of the important reasons for insulation eccentricity. In sheath extrusion, the scratch on the surface of the jacket is also often caused by the bending of the core. Therefore, alignment devices in various extrusion units are essential. The main types of straightening devices are: drum type (divided into horizontal and vertical); pulley type (divided into single pulley and pulley group); winch type, which combines dragging, straightening, and stable tension; Pressure roller type (divided into horizontal and vertical).

Preheating device

Core preheating is necessary for both insulation extrusion and jacket extrusion. For the insulating layer, especially the thin layer insulation, the existence of the pores cannot be allowed, and the core can completely remove the moisture and oil on the surface by preheating before high temperature. For sheath extrusion, its main function is to dry the core to prevent the possibility of voids in the jacket due to moisture (or moisture surrounding the cushion). Preheating also prevents the internal pressure of the plastic from being quenched during extrusion. In the process of squeezing plastic, preheating can eliminate the disparity temperature difference formed when the cold wire enters the high-temperature machine head and contact with the plastic at the die mouth, avoiding the fluctuation of the plastic temperature and causing the fluctuation of the extrusion pressure, thereby stabilizing the extrusion amount and ensuring Extrusion quality. The electric heating core preheating device is used in the extrusion unit, which requires sufficient capacity and ensures rapid heating so that the core preheating and core drying efficiency are high. The preheating temperature is limited by the speed of the line, and is generally similar to the temperature of the head.

Cooling device

After the formed plastic extrusion layer leaves the machine head, it should be cooled and shaped immediately, otherwise, it will be deformed under the action of gravity. The cooling method is usually cooled by water and divided into quenching and slow cooling depending on the water temperature. Quenching is the direct cooling of cold water. Quenching is beneficial to the shaping of plastic extrusion coating. However, for the crystalline high polymer, due to rapid cooling, it is easy to residual internal stress in the extrusion layer, resulting in cracks during use. PVC is generally used. The plastic layer is quenched. Slow cooling is to reduce the internal stress of the product. Different temperatures of water are placed in the cooling water tank to gradually cool down the product. The extrusion of PE and PP is carried out by slow cooling, that is, through hot water, warm water and cold water. Three sections of cooling.

  Control System

The control system of the plastic granulator includes a heating system, a cooling system and a process parameter measurement system, and is mainly composed of an electric appliance, a meter and an actuator (ie, a control panel and an operation console). Its main function is: control and adjust the drag motor of the main and auxiliary machines, output the speed and power according to the process requirements, and enable the main and auxiliary machines to coordinate work; detect and adjust the temperature, pressure and flow of the plastic in the extruder; Control or automatic control of the entire unit.

The electrical control of the extrusion unit is roughly divided into two parts: transmission control and temperature control, which realizes the control of the extrusion process including temperature, pressure, screw revolution, screw cooling, barrel cooling, product cooling and outer diameter, and traction speed. , neatly arranging the line and ensuring constant tension take-up control from the empty plate to the full plate on the take-up reel.

1. Temperature control of the extruder mainframe

The plastic extrusion of the wire and cable insulation and the sheath is based on the deformation characteristics of the thermoplastic, making it in a viscous flow state. In addition to the external heating of the screw and the barrel, it is transferred to the plastic to melt and extrude. It also considers the heat generated by the screw when extruding the plastic. Therefore, the temperature of the main unit should be considered from the whole, considering the heating and opening of the heater. Close, it is necessary to consider the factors of the extrusion head of the screw to cool, and to have effective cooling facilities. It is required to correctly and reasonably determine the position and installation method of the thermocouple of the measuring component, and accurately reflect the actual temperature of each segment of the host from the reading of the temperature control meter. And the accuracy of the temperature control instrument is required to cooperate with the system so that the fluctuation stability of the whole host temperature control system reaches the extrusion temperature requirements of various plastics.

2. Pressure control of the extruder

In order to reflect the extrusion of the machine head, it is necessary to check the head pressure during extrusion. Since the domestic extruder does not have a head pressure sensor, it is generally used to measure the thrust of the screw after extrusion, instead of the head pressure measurement, the screw load table (Electrometer or voltmeter) correctly reflects the extrusion pressure. The fluctuation of extrusion pressure is also one of the important factors causing the instability of extrusion quality. The fluctuation of extrusion pressure is closely related to the extrusion temperature, the use of a cooling device, and the length of continuous operation time. When an abnormal phenomenon occurs, the rapid elimination that can be eliminated, the reorganization of production must be decisively stopped, not only can avoid the increase of waste, but also prevent accidents. By detecting the pressure gauge reading, it is possible to know the pressure state of the plastic during extrusion, and generally, take the back pressure limit value alarm control.

3. Control of screw speed

The adjustment and stability of the screw speed is one of the important process requirements of the main drive. The screw speed directly determines the amount of glue and the extrusion speed. The normal production always wants to achieve the highest speed and achieve high output. When the extruder requires the screw speed from starting to the required working speed, the available speed range is large. . Moreover, the stability of the rotational speed is required to be high, because the fluctuation of the rotational speed will cause the fluctuation of the extrusion amount and affect the extrusion quality so that the change of the outer diameter of the cable will occur if the traction linear velocity does not change. Similarly, if the linear velocity of the traction device fluctuates greatly, the outer diameter of the cable will change. The speed of the screw and the traction wire can be reflected by the corresponding instrument on the console. The extrusion should be closely observed to ensure high quality and high yield.

4. Control of the outer diameter

As mentioned above, in order to ensure the size of the outer diameter of the product cable, in addition to the dimensional tolerance of the control core (core), the extrusion temperature, the screw speed, the linear speed of the traction device, etc. should be controlled, and the outer diameter The measurement control comprehensively reflects the accuracy and level of the above control. In the extrusion unit equipment, especially the high-speed extrusion production line, the online outer diameter detector should be used to detect the outer diameter of the cable at any time, and the over-range signal is fed back to adjust the speed of the traction or screw to correct the outer diameter. Very bad.

5. Tension control required for winding

In order to ensure the wire take-up at different line speeds, the constant tension requirement from the empty plate to the full plate operation, it is desirable to have the wire tension adjusting mechanism for the wire receiving device or to electrically consider the winding of the constant linear speed system and the constant tension system. and many more.

6. Electrical automation control of the whole machine

This is the process control requirement for high-speed extrusion production line, mainly: start-up temperature interlocking; working pressure protection and interlocking; proportional synchronous control of extrusion and traction two major components; synchronous control of take-up and traction; On-line detection and feedback control of the outer diameter; control of the single machine and the whole machine tracking of the components according to various needs.

Plastic granulator plastic processing equipment

As long as there are human places, there are waste plastics, all kinds of waste plastics, such as bags, woven bags, pots, barrels, plastic doors and windows, toys, home appliance casings, waste plastic products in beverage bottles, and waste in plastic molding process. Wait, it can be seen everywhere. The plastic structure is stable, not easily degraded by natural microbial bacteria, and does not separate in the natural environment for a long time. This means that if the waste plastic waste is not recycled, it will become a permanent pollutant in the environment and accumulate, which will cause great harm to the environment.

Plastic raw materials are chemical products extracted from natural petroleum. Petroleum is the lifeblood of modern industry and a non-renewable natural resource. Therefore, recycled plastic is petroleum regeneration. The use of waste plastics for melt granulation can alleviate the contradiction between supply and demand of plastic raw materials. Today, manufacturers of plastic granulators take everyone to know how plastics are recycled.

1. There is too much plastic garbage in the life of the finished equipment warehouse area, and we should adopt that way to be economical? Discard: become white pollution, not decay for decades; combustion: produce a lot of secondary pollution; cracking refining: investment Huge, the relevant technology is still immature and cannot meet national targets. Is there a way to solve white pollution and create huge economic benefits, and is also feasible in terms of recycling methods? The answer is yes - That is to achieve secondary production through recycling and recycling: It can not only turn waste into a profitable country but also create huge social and economic benefits. With this problem, we will find a professional manufacturer of plastic recycling equipment.

 2. Q: Which plastics can be recycled in real life? A: As long as it is a thermoplastic plastic in real life, that is to say, plastics that can be softened when heated to a certain temperature, for example, a large number of industrial plastics, civilian plastics, packaging plastics, electronic appliances The casing can be recycled almost all.

3. Q: What kind of processes are involved in plastic recycling? What are the uses of recycled raw materials? A: Simply put, there are two major processes - first, pretreatment (that is, classification, plastic crusher crushing, plastic washing machine cleaning) ) become a semi-finished product - followed by granulation (that is, the semi-finished product causes recycled particles), which can be used to make plastic products, such as plastic pots, plastic buckets, plastic tubes, non-woven fabrics, etc. - It can also be used for deep and fine processing (that is, advanced processing such as mixing, modification, and coloring of recycled plastics to meet higher usage requirements and maximize economic benefits).

4. Q: What should I pay attention to when investing in plastic recycling? Plastic granulator manufacturer A: Since plastic recycling is almost always under high temperature, high pressure, water, and other harsh conditions, the key is to choose Excellent equipment, then complete technical guidance and after-sales service guarantee, and finally have reliable venues and facilities.

Plastic granulator production line

1. Feeding: belt feeding, frequency conversion control, and when the compacting machine current reaches the set value, the belt will automatically stop. When the current drops, the belt will start automatically. If the customer requests metal detector, we can also realize Linked, when the metal detector alarms, the belt will stop, and the belt will start after the alarm is removed. If the customer feels that the metal detection is too expensive, we can also make a strong magnetic belt roller for iron removal. Of course, the price will increase.

2, feeding, the compact machine combined with the role of the pellet machine, and in order to increase the speed and effect of the pellet, we made changes in the cutter and fixed knife of the compact machine, in order to facilitate the feeding, installed in the pot The deflector has been improved at the screw feed port.

3, in order to control the compact machine, we also made our own design, the material is sheared, rotated and rubbed in the pot body, the temperature will rise continuously, and then shrink into a group, it is already half when entering the screw of the plastic granulatorIn the plasticizing state, the heat energy required in the screw will be reduced, the heating time will be shortened, the feed will be more, the material will be faster, and the output will naturally become higher (more material is fed, and the material is not timely, the screw It will be stuck, this will not work. There is less material to feed, no production, no.)

The temperature at which the material enters the screw of the plastic granulator is also important. The higher the temperature, the higher the yield naturally, but if it is too high, the material will stick to the block in the pot. As the saying goes, it is a paste pot. Once the material is formed into a single piece, it is impossible to enter the screw, and it needs to be shut down for cleaning. Therefore, controlling the temperature of the material in the compact pot is an important and complicated task. This is also our advantage over other peers.

Analysis of the importance of plastic crusher to prevent moisture

As long as there is a problem with metal-made things, it is rust. Of course, plastic crushers also face such problems as other metal equipment. If the storage location is not good, for example, long-term storage in a humid place, it may cause rust in the plastic crusher. Although the surface of the plastic crusher is painted with paint the inside of the equipment is not, it is prone to rust. Therefore, plastic crusher should be as good as other equipment to prevent moisture.

We will find in daily life that when you pick up a thing if this thing is relatively simple, it is easy to crush. Therefore, the same is true when using a plastic crusher to crush materials. The dry materials are more likely to be broken, and for some materials with high toughness or high humidity, they are not easily broken. At this time, it will affect the crushing effect of the plastic crusher. Therefore, if you want to ensure the output of the plastic crusher, you should avoid long-term processing of materials with high water content, and secondly, avoid the long-term work of the plastic crusher in the sun and rain.

Plastic bottle crusher

The plastic bottle crusher is specially designed for the crushing of mineral water bottles, beverage bottles, plastic bottles, and preforms. Because most of the raw materials for beverage bottles and mineral water bottles and preforms are PET, it is easy to generate static electricity after rubbing, so that the crushed bottle The sheet adheres to the cutter and the screen and is not easy to cut. Qinfeng plastic bottle crusher series adopts high-speed steel laminating tool, which utilizes the super hardness of the tool to enhance the cutting function and the screen is hard chrome-plated. At the same time, since the round-shaped hollow bottle is easily pulverized in the pulverization chamber during the pulverization process, it cannot be pulverized. The plastic bottle pulverizer adopts a hollow turret to enable a larger rotating diameter during the rotation of the tool, and tightly hugs the bottle to crush and cut so that the smashing is smoother. Operating procedures

1. Plastic bottle crusher production operation process

1. Look at the rotation direction of the plastic bottle crusher impeller from the feed port. The flywheel impeller should rotate counterclockwise. If it rotates clockwise, check the motor connection line.

2. If equipped with automatic feeding conveyor, when the conveyor stops running, the feeding should be stopped immediately, because the conveyor should be interlocked with the feeding system to open and stop, otherwise it will cause the impeller to be crushed, thus burning the motor or causing equipment. Damage

3. The plastic bottle crusher must be continuous and uniform during the feeding process. Do not feed the material larger than the specified size. When large pieces of material are found, they should be removed in time. Otherwise, the imbalance of the impeller and the excessive wear of the impeller may be caused, or even The crusher is stuck so that the crusher cannot work normally and burn the motor;

4. In the production process of the crusher, there are severe vibrations and abnormal noises. It should be stopped and checked immediately. After the fault is discharged, it can work again in order.

2. Plastic bottle crusher routine maintenance

1. Regularly stop the inspection to check the wear of the internal parts of the crusher. The worn parts should be replaced or repaired in time. After the wear block is worn, it should be replaced at the same time. It is found that the wear of the impeller should be replaced in time or repaired by the manufacturer. To ensure the balance of impeller operation;

2. The crusher uses grease, the amount of addition is 1/2-1/3 of the bearing cavity, the crusher works 300-400 hours to add the appropriate amount of grease, work 2000 hours to open the spindle assembly to clean the bearing, work 7000 hours - 10000 hours, new bearings should be replaced;

3. In the normal working condition of the plastic bottle crusher, it is forbidden to open the observation to avoid dangerous accidents;

4. The driving belt tensioning force should be adjusted to the appropriate size to ensure uniform force on the V-belt so that the equipment can work smoothly and normally;

5. The plastic bottle crusher is high-speed operation equipment. When the crusher is running, special attention should be paid to safety production. The operator should operate in the designated position, and the unrelated personnel should be away from the equipment.

How to repair the damage of the plastic extruder barrel

Repair of the barrel

 The inner surface of the barrel is harder than the plastic extruder screw, and its damage is later than the plastic extruder screw. The scrapping of the barrel is such that the diameter of the inner diameter increases due to time wear.

Its repair method is as follows:

 1. The barrel with increased diameter due to wear. If there is a certain layer of nitrided, the inner hole of the barrel can be directly bored, ground to a new diameter, and then the new plastic extruder screw can be prepared according to the diameter.

 2. The inner diameter of the barrel is machined and trimmed to recast the alloy, the thickness is between 1"2mm and then finished to the size.

 3. Under normal circumstances, the homogenization section of the barrel wears faster. This section (take 5"7D long) is trimmed by the boring, and then a nitriding alloy steel bushing is used. The diameter of the inner hole is referenced to the screw of the plastic extruder. The diameter is left in the normal fit-gap for processing and preparation.


4. It is emphasized here that the two important parts of the plastic extruder screw and barrel are an elongated threaded rod and a small diameter and long hole. Their machining and heat treatment processes are complicated. The guarantee of accuracy is more difficult. Therefore, after the wear of these two parts is repaired or replaced with new ones, it must be comprehensively analyzed from an economic perspective. If the repair cost is lower than the screw cost of the new plastic extruder, it is decided that repair is not necessarily the correct choice. The comparison between the repair cost and the update cost is only one aspect. In addition, the cost of the repair and the ratio of the screw time and renewal cost of the plastic extruder to the renewal of the screw time of the plastic extruder are also observed. It is economical to adopt a scheme with a small ratio and is the right choice.

5, plastic extruder screw and barrel manufacturing materials

 6. Manufacture of plastic extruder screw and barrel. Currently, commonly used materials are 45, 40Cr and 38CrMoAlA.

7, imported plastic extruder shuliy material extruder screw and barrel manufacturing materials, commonly used alloy steel has 34CrAINi7 and CrMoV9. The yield strength of this material is about 900 MPa. After nitriding treatment, the hardness is above 1000 HV, which is both wear-resistant and has good corrosion resistance.

Analysis of plastic pellet machine characteristics

The plastic pellet machine is mainly used for processing and processing waste plastic film (industrial packaging film, agricultural film, greenhouse film, beer bag, handbag, etc.), woven bag, agricultural convenience bag, basin, barrel, beverage bottle, furniture, daily necessities, etc. Most common waste plastics,

Plastic granulator features:

1. All recycled plastics can be produced, dried and wet after being sorted, crushed and cleaned without drying or drying.

2. From raw material crushing, cleaning, feeding to pelletizing are automated.

3. Make full use of the high-pressure friction uninterrupted heating system, automatic heating production, avoiding continuous heating, saving energy and energy.

4. Electromechanical separation, simpler operation, and safer use.

5. The screw barrels are made of high-strength and high-quality carbon structural steel, which is durable.

6. The appearance of the machine is beautiful and generous. Can be painted according to customer requirements.

Plastic granulator function: It adopts special screw design and different configuration, suitable for the production of various plastics for regeneration and color mixing granulation. The high-torque design of the gearbox achieves smooth, noise-free operation. The screw and barrel are specially hardened, with wear resistance, good mixing performance, high output characteristics, vacuum exhaust or ordinary exhaust port design, which can remove moisture and exhaust gas during production. It is more stable and the rubber particles are stronger, which guarantees the excellent quality of the products.

What are the commonly used plastic films?

Plastic granulator manufacturers provide: the commonly used plastic film is 1. Polyethylene film (PE), 2. Polyvinyl chloride film (PVC), 3. Polystyrene film (PS), 4. Polyester film (PET), 5. Nylon, 6. A polypropylene film (PP), etc.

PE film is a colorless, odorless, odorless, translucent non-toxic insulating material, used in a large number of bags; food bags can also be made into a variety of containers. It is an inert material, so it is more difficult to print and must be processed before it can print better results. For this PE film, Puri uses a horizontal water ring pelletizing system that is easy to operate. Compared to several other plastic films, this PE film is easier to recycle after all.


PP film has good gloss and good transparency, heat-resistant acid and alkali, solvent resistance, friction resistance, tear resistance, and gas permeability. It cannot be heat sealed when it is lower than 160 °C. Puri uses a vertical water ring pelletizing system.

PVC film has good light resistance and aging resistance and has good tear resistance. It is breathable. It is a clean, colorless and transparent film. It is usually added with a plasticizer. It is soluble in acetone and ring. A solvent such as a ketone. Therefore, it can be printed with an ink made of a polyvinyl chloride resin. Suitable for packaging bags, book covers, etc.

PS film is a soft and tough film, clean, colorless and transparent. When it is free of plasticizer, the film is always soft, resistant to freezing, and stored without aging. The oxidative polymerization of synthetic binder ink can be used for printing. Good degree.

PET is colorless, transparent, moisture-resistant, air-tight, soft, strong, acid-base oil ester and solvent, and is not afraid of high and low-temperature materials. After EDM treatment, it has better surface fastness to ink. Used in packaging and composites.

Nylon film is stronger than polyethylene film, odorless, non-toxic, impervious to bacteria, oil, ester, boiling water, and most solvents. It is generally used for load-bearing, wear-resistant packaging, and retort packaging (reheating of food) It can be printed without surface treatment.

The performance of various plastic films is different, the degree of difficulty in printing is also different, and the use as a packaging material is also different. If you want to know more about plastic machinery, you can log in to the following website.

Use of plastic pellet machine

Use of plastic pellet machine

Many people around are planning to open a small factory and buy a plastic pellet machine to do small business for recycling waste plastics.

All kinds of plastics (agricultural film, preparation bags, convenience bags, beverage bottles, plastic buckets, old sandals, etc.) can be processed into plastic particles, which are mechanically operated from cleaning to pelletizing. Recycled granules are widely used in various types of plastic products manufacturers, such as bag factories, cement bag factories, blown film factories, etc. The scale of production can be large or small, and the site is 120 square meters. Water and electricity are convenient to put into production, plastic particle production line consists of: waste plastics classification → crushing and cleaning → extrusion granulation

However, the plastic pellet machine is very confused. I don’t know what the particles made by the plastic pelletizer are used for. What kind of benefits can these plastic pellets bring to themselves?


Now, Puri introduces the use of these plastic particles.

Firstly, the concept of plastic particles is introduced. Plastic particles are commonly called plastic particles, semi-finished products, and a polymer material. It is a compound made of petroleum as a raw material to produce ethylene, propylene, etc., under certain conditions.

What is the effect of waste plastic recycling on the greening environment?

Actively develop waste plastic granulators to use industrial power in the contemporary, and benefit from the future. Recycled plastics are plastics that have been recycled from new materials or discarded plastics that have been produced by a mast machine and then cut into pellets by a pelletizer. a plastic particle. Waste plastics and plastic resources are called by modern economists as the second mineral of mankind and the treasures of the city. By using the waste plastic recycling granulator, the contradiction between the supply and demand of plastic raw materials can be alleviated, and the foreign exchange of crude oil imported by the state can be saved. In addition, because most plastics are not degradable, they accumulate over time, causing serious white pollution and destroying the ecological environment of the earth. The disposal of waste is not only difficult but also has a huge impact on the environment.


The recycling and recycling of waste plastic granulators have become an important and beneficial supplement to the supply of plastic raw materials, which can effectively alleviate resource shortages. At present, the recycling of recycled plastics has played a huge role in promoting environmental protection, expanding employment, increasing taxation and regional circular economy development, effectively promoting energy conservation and emission reduction, and consolidating China's manufacturing low-cost competitive advantage for China's economic construction. Contribution to the development of the circular economy and environmental protection.

Analysis of common failures of plastic granulator machine

There are many common fault analysis of plastic granulator machines. The following granulator manufacturer Fidelity Machinery explains the reason why the torque of the main motor of plastic granulator machine is too low. The main reason for the low torque of the main motor of plastic granulator is that Material system failure Twin screw idling will cause the main motor torque to be too low.

 Solution: Check whether the plastic granulator machine additive system or the main material cutting system is faulty and clean the plugging point.

 Plastic granulator machine friction clutch failure, the main reason for this failure is that the initial motor voltage is too low, the friction plate, the friction plate is overheated, the friction plate and the friction plate are aging, the air pressure of the friction plate is too low, etc. open.

 Remedy: When starting the main motor, avoid the peak of power consumption and reduce the feeding load. The interval between restarts is as short as 30 minutes. In summer, when the main motor is restarted more than twice, the interval should be extended. The fan is forced to cool down. Use the instrument wind to sweep and wipe the surface of the friction plate and the friction plate with a rag. If the wear is heavy or the surface appears “glass flower”, the friction plate and friction plate should be replaced. Check if the air pressure value matches the friction disc to the friction plate.

What is the role of the plastic granulator?

The function of the plastic granulator is to reprocess the recycled waste plastics, such as greenhouse film, woven bags, plastic bags, plastic sandals, etc., into hot-selling plastic granules.

    The performance indicators of activated carbon products include physical properties, chemical properties, adsorption properties, and three properties. The adsorption of activated carbon can be divided into physical adsorption and chemical adsorption.



    The physical adsorption of the plastic granulator mainly occurs in the process of removing impurities from the liquid phase and the gas phase by the activated carbon. The porous structure of activated carbon has a large surface area, making it easy to absorb impurities. Just like a magnetic force, all molecules have mutual attraction. Because of this, a large number of molecules on the pore walls of the activated carbon can generate strong gravitational force, so as to attract impurities in the medium into the pores. It must be pointed out that the molecular diameter of these adsorbed impurities must be smaller than the pore diameter of the activated carbon so that it is possible to ensure that the impurities are absorbed into the pores. That's why we create activated carbon with different pore sizes by constantly changing raw materials and activation conditions, making it suitable for a variety of impurity absorption applications.

    Plastic granulator complete set of equipment waste plastic crusher, loading machine, washing machine, granulator, pelletizer, the complete set of units, can be automatically and continuously produced, due to special exhaust and drainage equipment, the waste is washed After drying, it can be directly granulated, and the granulation is clean, without pollution and aging, which greatly reduces the production cost and improves the production efficiency. The whole machine has the characteristics of small size, high efficiency, good performance, low power consumption, high quality of finished products and wide adaptability. It can meet various processing requirements and is suitable for different waste plastics.

Causes the plastic pelletizing machine to stop instantaneously

The reason why the plastic pelletizing machine mainframe does not roll or stop suddenly causes the fault to be caused by the power of the main motor is not turned on, or the heating time is high, or one of the heaters does not work, causing the torque to be too large and the motor is overloaded. . The fault is handled by checking whether the host circuit is turned on, turning on the power; checking the temperature display of each segment, confirming the warm-up temperature rise time, checking each heater for damage or poor contact, and eliminating it.


  The main pelletizing machine of the plastic pelletizing machine rolls, but the screw does not turn to cause the failure: the transmission V has a loose bandwidth, wear and slip; or the safety button loosely falls off or disconnects.

  This fault is handled by adjusting the V-belt center distance, tightening the belt, or replacing the new V-belt; checking the safety key, analyzing the cause of the break, and replacing the safety key.

  The plastic pelletizing machine screw runs normally, but the reason for the failure is that the hopper feed is not continuous; or the feed port is blocked by foreign matter; or "bridge" occurs, or the metal is dropped into the groove The hard object blocks the screw groove and cannot be fed normally; the treatment of this fault: increase the feeding amount so that the screw feeding is continuous and not disordered; stop the inspection to remove the foreign matter in the material port to eliminate the "bridge" phenomenon; if it is confirmed that the metal foreign matter falls into the snail The screw should be stopped immediately to disassemble the screw to remove metal foreign matter.
