Crusher
There are many types of plastic crusher, suitable for crushing all kinds of plastic products with shear crusher. They are suitable for crushing brittle plastic products with the impact of the type and the compression type crusher, etc. Shear crusher is widely used. It is made up of frame, crushing chamber, the feed hopper, sieve plate, drive mechanism, rotating and stationary knife.
Shear type plastic crusher works under simple condition: the shear cutter is composed of rotating blade and fixed blades; rotating knife is driven by a motor; Send to crushed waste plastics are sent by the feed hopper to the crushing chamber, after high speed rotating cutter were chopped, and then they flow outside through the porous sieve plate.
Cleaning machine
The function of the washing machine is to remove the dirt from the withered in the plastic and the sediment after leaving waste plastic in the sink through urning, mixing and water washing with a pair of rotating mixing blade. Then the lifting device takes out plastic debris from the water to the dehydration process.
Dewatering machine
Dewatering machine structure is simple, and similar to household dryer structure. So working method. The moisture is dewatered out of broken plastic drum mainly by using high speed rotating centrifugal force.
Dryer
After crushing, washing and dewatering, plastic still has certain moisture. The function of the dryer is sending it through feeding mouth to the ram with hot air circulation. It is used to evaporate the material moisture, making plastic dry, to meet the needs of the extrusion granulation process.
Extruder
Extruder is exhaust type, whose role is to put the broken, clean and dry plastic mixed, heated and pelletized by extruder.
Because of the complex source of the waste plastic products, there are various types to the composition of the mixture model. Material contains lots of olatile matter, water and other components, so it is appropriate to choose exhaust type extruder .
Exhaust type extruder melts mixed scrap plastic with special shape of material, so it needs spiral forced feeding; the filter added in front of barrel, molten material is pelletized after extruded from porous plate. Waste back to the system is sized dicing after material is extruded blends cooling in the sink to finalize the design.
