The film granulating machine production mode of crushing, hot-melt extrusion, cutting and drying is adopted, which solves the great danger of artificial feeding and forced feeding of soft throwing materials with small bulk density such as films and woven bags during the recycling and granulation process.
The PE film granulating machine production mode of crushing, hot-melt extrusion, cutting and drying is adopted, which solves the great danger of artificial feeding and forced feeding of soft throwing materials with small bulk density such as films and woven bags during the recycling and granulation process. The material output is small, the manual consumption of the split operation of crushing and extrusion is large, and the particle size of the strands is not uniform, and the strands are easily broken.
The film granulating machine production of the film granulation line has increased output by 20%, energy consumption has been reduced by 15%, and is highly automated: the plastic film granulator requires only 2 staff.

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
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.
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.
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
