Plastic granulator hopper

Shuliy plastic granulators For a given process, the plastic used should be measured to determine the amount of material in the hopper. According to the regulations, the material required for the production of 0.5-1h should be stored in the hopper. This kind of measure also avoids the excessive residence time of the material in the hopper. It should be noted that the storage time of the hygroscopic plastic in the unheated hopper shall not exceed 0.5-1 h, or the time of the material in the hopper shall be determined according to the experience and the requirements of the manufacturer.

Different devices can be installed on the granulator hopper to give it various functions, such as installing a hinged or tightly mounted slide and magnetic mesh to prevent moisture absorption and metal doping, respectively. Generally, when processing abrasives, pigments, and hygroscopic materials, a hopper dryer should be installed, which is very useful for controlling the processing of materials and discharging moisture.

In the design of the plastic granulator hopper, in addition to the material flow caused by the consideration is too small, mechanical and vibration methods can be used to strengthen the continuous feeding into the extruder. A slotted horizontal slab is installed at the bottom of the hopper of the plasticizing device, and the feeding rate is controlled by changing the rotation speed or clearance of the disc, and the material on the disc is removed by a scraper. The granulator can also be equipped with a vibrating device to prevent the material from sticking to the hopper wall, promoting material movement and eliminating material bridging.

Plastic pellet machine should be operated carefully

In the use of some machines, many people go wrong, causing more serious accidents, such as the use of waste plastic pellets often do not pay enough attention, it will also cause some unnecessary accidents. , Shuliy plastic pellet machine manufacturers reminded us what issues should we pay attention to when using the pellet machine?

During the operation, do not use low-quality materials with metal impurities or sediment. Do not place metal objects that may fall into the vicinity of the feed port to prevent the screw or barrel from being damaged or jammed or damaged. phenomenon.

Pay attention to fire safety, fire extinguishers need to be placed near equipment that uses heat transfer oil. In the event of a malfunction or abnormal condition, the person concerned must be reported and handled by the service personnel. If it is found that there is an abnormal phenomenon affecting safety, immediately press the emergency stop switch.
