Cleaning and drying of waste plastic

There are two methods for cleaning and drying waste plastics: mechanical cleaning and manual cleaning. Some plastic products can only be cleaned manually after recycling, and some plastic products can be mechanically cleaned and dried. The following are the specific operations of mechanical cleaning and drying.

Mechanical cleaning and drying are divided into batch and continuous. Intermittent cleaning First, wash the waste plastic into a water tank, and use a plastic mixing machine to remove loose dirt such as sand, dirt, etc. that are stuck to the surface of the plastic and sink it to the bottom of the tank; if there are many wood chips and paper, It can be further purified in a sedimentation tank equipped with a special pump; for dirt that is firmly attached, such as printing inks and adhesive-coated paper labels, you can manually pick out larger pieces and put them in after crushing by a plastic grinder Soak in the hot alkaline solution tank for a period of time, and then rub and rub each other with mechanical stirring to remove dirt. Finally, the washed and crushed waste plastic is sent to a centrifuge to be dried, and dried in two steps of hot air to residual moisture of ≤0.5%. Continuous cleaning The waste plastic is sent to the plastic crusher by the conveyor belt for coarse crushing, and then sent to the large separation section.

The floating material enters the wet mill through the conveying roller, and then enters the sedimentation tank. Everything heavier than water is separated, even the smallest particles are no exception, achieving the best cleaning effect. The new generation of crushing and washing integrated machine developed by the production not only keeps the ruggedness of the original body, but also undergoes technological innovation to produce products that are not only durable but also have a significantly improved cleaning effect than before. Buying machinery to make you successful is not a dream.
