The PP PE plastic pelletizing line is a key technology that helps reduce resource waste and environmental pollution by converting waste plastic film into reusable plastic pellets. This article will introduce the 6 key steps of PP PE plastic pelletizing line.
Step 1: Crushing in PP PE plastic pelletizing line
The first step in the plastic film washing recycling line is to feed the sorted plastic film waste into the industrial plastic shredder. This crusher is capable of shredding the waste plastic film into small pieces. Shredding increases the surface area of the plastic, making it easier to process and increasing the efficiency of subsequent processing.
Step 2: Washing
After being processed in the industrial plastic shredder, the plastic may have some contaminants attached to them, such as dust, dirt, and residual organic matter. Therefore, in the second step, the plastic is fed into lavadora de pelicula plastica. The washing machine utilizes water flow and friction to remove surface impurities and ensure the purity of the plastic for the subsequent production process.
Step 3: Dehydration
After washing, the plastic pieces still contain water. The third step is to feed the plastic into secadora de plastico. Using hot air, the dryer evaporates the water to bring the plastic to the proper moisture content. Ensuring that the plastic is dry, as too high a moisture content may affect pelletizing results.
Step 4: Plastic pelletizing
This is the core step in PP PE plastic pelletizing line. The Extrusora de plástico PP PE processes the plastic through high temperatures and pressures. The plastic is heated and melted and then extruded into a continuous plastic strip.
Step 5: Cooling
After initial pelletizing, the plastic lengths are still at a high temperature. The fifth step is to feed the plastic lengths into a cooling tank. The cooling tank is filled with cooling water or other cooling medium, which quickly reduces the temperature of the plastic strip and solidifies it. The cooling process also helps to improve the density and quality of the pellets.
Step 6: Cutting and storage
Finally, the cooled plastic strips are fed into the cortadora de pellets de plástico. The plastic pellet cutting machine is able to cut the plastic strip into the desired size and shape to ensure that they meet the customer’s requirements. The customized plastic pellets are then stored in a storage silo for further packaging and marketing.
