Plastic pelletizing recycling machine is mainly used in PE, PP, HDPE, LDPE, LLDPE, BOPP film, plastic bag etc.
Plastic pelletizing recycling machine adopts special design for the venting can discharge the moisture and waste air efficiently which ensure the finally plastic granules are with smooth surface, no water, no bubble, and good quality. Special designed force feeder, side feeder and compactor can push the material into the extruder high efficiently.
Plastic pelletizer machine is mainly used in PE, PP, HDPE, LDPE, LLDPE, BOPP film, plastic bag etc. For dirty films, Purui Machinery can provide a plastic film washing line for cleaning, and start pelletizing after drying. For relatively wet films, we can use two-stage plastic pelletizing machine for pelletizing.
Two type cutting way, the noodle type and water ring type makes the customer freely to choose. All die holes size are special designed due to the material characters and our rich experience to make plastic pelletizing machine.
Plastic pelletizing recycling line integrates crushing, conveying and pelletizing, assembly line work. Plastic pelletizing recycling line has labor saving & higher efficiency, reliable equipment configuration, complete functions, excellent comprehensive indicators and performance, high automation, suitable for professional users having certain strength and scale.
Normal:
| Model | SJ45 | SJ65 | SJ90 | SJ100 | SJ120 |
| Output(kg/h) | 10-60 | 100-150 | 180-250 | 250-350 | 300-600 |

| Model | SJ150 | SJ160 | SJ180 | SJ200 |
| Output(kg/h) | 400-700 | 600-1000 | 1500-2000 | 2000-3000 |
Belt Conveyor
As standard design, plastic scraps such as film, filament, raffias conveyed into the compacting room through belt conveyor; to handle rolls’ scraps, roll hauling off device is an optional feeding method. Motor drives of conveyor belt and hauling device cooperate with ABB inverter. Feeding speed of conveyor belt or roll hauling off is fully automatic based on how full the compactor’s room is. Metal detector can be combined with belt conveyor, and can interlock with contrl system, to warn and stop the system, in case that metal is found in feeding.
Compactor / Agglomerator
The rotatory blades of compactor will cut up incoming scraps. Frictional heating which caused by high speed rotatory blades will heat and let scraps shrinking just below their agglomerating point. Optimal designed guide structure compacts the material and directs it into extruder screw. Crushes, dries and compacts the material which enables a fast and stable feeding from the compactor directly into the extruder.
Extruder
A specialized single screw extruder applied to gently melt the pre-compacted material. The plastic scraps will be well melted, plasticized in a 36D processing section. With double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiency, especially suitable to heavy printed film and material with water content
Water-ring Die-face cutting system
Water-ring die-face/Strand cutting methods are usually adopted. In water-ring die-face cutting system, the rotary cutting blades will be pneumatically fit completely and closely to the die-face surface to ensure efficient cutting. Rotary speed of the blades is automatically adjusted by module system according to melt pressure at the die face.
Vibration drying system
Advanced dewatering vibration sieve combing with horizontal-type centrifugal dewatering present high performance dried pellets and lower energy consumption.Combine crushing, compacting and plletizing steps in one system, less-labor cost.Higher efficiency feeding, suitable to film, filament, raffia, foaming materials;Higher output and lower energy consumption
