Plastic film pelletizing production line is mainly used for the recycling and granulation of plastic film.
Plastic film pelletizing production line is mainly used for the recycling and granulation of plastic film. The recycled plastics of different shapes, different degrees of cleanliness, and even different components can be granulated to obtain plastic particles of the same size and material properties. In terms of mechanical configuration, the plastic film pelletizing machine generally adopts a sub-machine (or dual-line) granulation.
According to the purpose, the plastic film pelletizing line is mainly to purify and produce uniform particles. The mechanical characteristics are mainly to adapt to the characteristics of the raw materials (such as the drainage design of water-containing plastics. When there are more impurities, a larger die is required. Or change the net automatically).
After sorting and sorting the plastic film, put it into a water injection crusher for crushing, and then wash it as it breaks. The broken recycled plastic can be directly extruded for production without drying it in the sun. Draining, exhausting, stripping and cutting can be completed at one time, simple operation, energy-saving and high-efficiency. The special exhaust design can effectively remove water vapor and exhaust gas, make the discharged particles more stable and firm, and ensure the excellent performance of the plastic film pelletizing machine.

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
