Working Process

The 125 Type PP Granulator adopts an integrated design with a concise and efficient process and a high degree of automation throughout, accurately adapting to the process characteristics of PP plastic melting, plasticizing, cooling and shaping, requiring little manual intervention and greatly saving labor costs. The specific process is clear and easy to understand, and novices can quickly master it, fully meeting the practical needs of PP granulation:

1. PP Material Pretreatment: Simply crush and sort PP waste plastics (PP woven bags, PP lunch boxes, etc.), remove impurities such as sediment, metal and fibers (can be used with a plastic crusher). No complex cleaning is needed, which simplifies operation steps, reduces labor costs, and at the same time reduces the wear of impurities on the equipment, avoiding affecting the quality of recycled PP granules and preventing yellowing caused by impurity mixing, which is a key link to ensure the quality of PP granulation.
2. Automatic Feeding: Send the pretreated PP materials into the feed inlet of the PP granulator main machine, and stably transport them into the barrel through the screw. The feeding speed can be flexibly adjusted through the frequency converter, which effectively avoids feeding blockage, ensures continuous production, does not require manual on-duty feeding, and adapts to the needs of continuous and stable processing of PP materials.
3. Heating and Plasticizing: Start the 60KW electromagnetic heating and heating coil, heat the barrel in sections to 160-240℃ (accurately adapting to the melting range of PP plastic), and the screw rotates at high speed to fully melt and plasticize the PP materials. At the same time, residual impurities are filtered through the screen changer to further ensure the purity of recycled PP granules, avoid uneven plasticization and material degradation, and ensure the stable quality of recycled granules, which is the core link of PP granulation.
4. Extrusion and Granulation: The plasticized molten PP plastic is extruded through the die head to form uniform plastic strips. After being quickly cooled and shaped by the stainless steel water tank (PP plastic needs precise cooling control to avoid internal stress and granule brittleness), it is sent to the 180-type alloy roller granulator, and uniform granules are cut out through frequency conversion speed regulation. The granule size can be flexibly adjusted according to downstream processing needs, adapting to different application scenarios of recycled PP granules.
5. Cooling and Drying: After the cut recycled PP granules are cooled by the water tank, they are automatically transported to the stainless steel silo, and quickly air-dried by the fan to remove the moisture on the surface of the granules, ensuring that the granules are dry and free of agglomeration, and can directly enter the packaging link without additional drying treatment, which greatly improves production efficiency and reduces production links.
6. Finished Product Collection: The dried recycled PP granules can be directly taken out from the silo, packaged and put into storage for secondary processing or direct sale, realizing a closed-loop whole process of “PP material pretreatment – granulation – finished product”, which is efficient and convenient, truly realizing the “turning waste into treasure” of PP waste plastics and creating considerable economic benefits for users.
