2. Plastic Melt Filters / Screen Changers Plastic melt filters and screen changers for extrusion and pelletizing lines includes self-cleaning filters and hydraulic screen changers, that support continuous filtration, stable extrusion, and improved recycled pellet quality. Learn more
2. Plastic Pelletizing Machines Plastic pelletizing machines are used after extrusion to cut molten plastic into finished pellets. Different cutting and cooling methods are available to match material type, output requirements, and pellet appearance. The strand pelletizer produces uniform cylindrical pellets by cutting cooled plastic strands. It is widely used for a variety of materials, including PP, PE, PA, PS, ABS, and PC to produce consistent pellet size. Learn more
2. Plastic Recycling Conveyor (Inclined Belt Conveyor) In recycling lines, the inclined belt conveyor are often seen between shredders, washing units, and pelletizing equipment to transport materials. The belt itself can be made from rubber or PVC, depending on the working environment and material type. Loose flakes and crushed plastics move especially well on this kind of conveyor, though it handles other materials just as reliably. Learn more
2. Plastic Recycling Feeder The forced feeder is used for soft, lightweight materials such as PP and PE films, woven bags, and similar crushed scrap. These materials are often fluffy and difficult to feed smoothly. The system provides steady, controlled feeding to the pelletizing machine and helps prevent bridging or unstable material flow. Learn more
2. Plastic Pellet Storage Silo The plastic pellet storage silo is used for storing finished pellets and supporting final packaging. Pellets are transferred from the hopper into the stainless steel storage tank by a high-pressure blower. When needed, material is discharged from the outlet for collection and packaging. The system is made up of a support frame, stainless steel tank body, turbine blower, and conveying pipelines. It is typically used together with a pelletizer and vibrating screen. Learn more
2. Vertical Plastic Granule Mixer The heated plastic mixer is equipped with a built-in heating and drying system that removes moisture from the material during mixing. It is especially suitable for recycled pellets and flakes with higher moisture content, helping improve melting uniformity and processing stability in subsequent production. Learn more
2. Plastic Extruder Heating System The heating system is a key part of any extrusion line. The heat provided during extrusion directly affects how evenly the plastic melts and how stable the whole process remains. After washing, the material is heated until it reaches a uniform molten state. Proper heating helps reduce impurities and trapped air, that enhances the pellet quality in the next stage. Learn more
2. Automatic Knife Grinder The automatic blade sharpening machine is used in plastic recycling and pelletizing operations to regrind crusher blades, especially flat knives. Over time, blades lose sharpness and cutting accuracy. It sharpens worn blades so they cut cleanly again for uniform pellet size. An automatic grinding feed system guides the grinding wheel across the blade surface with precision. Learn more
2. Plastic Dewatering Machine (Plastic Dryer) After crushing and washing, plastic materials still contain surface moisture. The dewatering machine removes this excess water at high speed before the next processing step. It is installed after coarse washing, crushing, and rinsing stages. Inside the machine, a screw pushes the material forward while centrifugal force separates water from the plastic. Learn more
2. Linear Vibrating Screen This linear vibrating screen handles both screening and conveying in one step. It grades plastic pellets by size while moving them forward, helping keep the production flow smooth. The screen mesh size ranges from 2 mm to 10 mm. It is suitable for dry powder or granular materials with particle sizes between 0.10–5 mm, moisture content below 7%, and no stickiness. Learn more
2. Vertical Screw Conveyor The vertical screw conveyor is used to move wet plastic materials after washing and crushing. It is generally used to transport materials like PE film, PP woven bags, and rigid PE or PP scrap from a lower level to a higher hopper in a pelletizing line. Such vertical transfer helps to reduce manual handling and supports precise and automatic feeding. Secondary contamination is also considerably reduced during the transfer. Learn more
2. Control System The control cabinet manages the operation, monitoring, and protection of key equipment across the plastic recycling and pelletizing line. Depending on the production scale and required control precision, different control solutions can be selected. Common types include standard electric control cabinets, PLC control systems, and frequency inverter control cabinets. Learn more
2. VOC Removal System During plastic pelletizing, additives and thermal processing can generate exhaust gases. During processing, the air released can contain volatile gases or VOCs like ethylene and propylene, as well as small traces of plastic dust. For workplace safety and environmental compliance, these gases need to be treated before discharge. Learn more
