Plastic film pelletizing extrusion line is suitable for many kinds waste plastic materials recycling and making pellet, such as PE/PP/HDPE film, plastic bags, materials, etc.
Plastic film pelletizing extrusion line is suitable for many kinds waste plastic materials recycling and making pellet, such as PE/PP/HDPE film, plastic bags, materials, etc. The plastic film can be pressed in compressor and then be pelleted. Plastic film pelletizing line has very developed design, makes sure this machine has a long working life and economical efficiency in using.
Plastic film pelletizing line adopts wind sending & gathering and vibration separate type cooling system which has high automation degree and production efficiency. Plastic film pelletizing line adopts horizontal water ring cutting system is more easy operate.
We have 2 options here for drying the wet cooled granules. One is vibrating screen,another is centrifuge force dryer. Plastic film pelletizing line is automatic and high efficiency and high output.

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
