PE film granulation machine integrates the functions of crushing, compaction, plasticization and granulation. Film granulation machine used in plastic recycling and granulation processes. The final product is in pellet form and can be placed directly into blown film, pipe extrusion and injection molding lines.
PE film granulation machine integrates the functions of crushing, compaction, plasticization and granulation. Film granulation machine used in plastic recycling and granulation processes. The final product is in pellet form and can be placed directly into blown film, pipe extrusion and injection molding lines.The film granulation machine includes compactor, film extruder, hydraulic station, screen changing system, pelletizing system, drying system and other equipment.
PE film granulation machine consists of two single-screw extruders, which are suitable for printing materials with heavy ink, high water content, poor fluidity, temperature sensitivity, and high impurity content, requiring higher requirements such as double filtration systems, multiple exhausts, and more process time long.

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
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.
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.
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.
