Plastic film pelletizer is used to process PE film, HDPE film, LDPE film recycling and granulation.
Plastic film pelletizer is used to process PE film, HDPE film, LDPE film recycling and granulation. The downstream equipment of the plastic film pelletizing production line includes: chute, centrifugal dehydrator, vibrating screen, air conveyor, silo, etc.
Plastic film pelletizing machine has the advantages of novel design, reasonable structure, stable operation, low noise, low energy consumption and high output. The plastic film pelletizing machine line has a variety of heating methods. The heating method can be designed according to the customer’s electricity capacity and cost of the production area, and according to the customer’s materials and output, we can provide customers with high-quality and reasonable plastic film pelletizing line.
1. The main and auxiliary screw and barrels are made of imported high-strength and high-quality carbon structural steel, which is durable.
2. The plastic film pelletizing machine adopts a conical screw barrel to speed up the feeding speed and greatly improve the output and quality.
3. The main and auxiliary machines are used for supporting production, the heating temperature is stable, the molecular structure of the material is effectively improved, the air permeability is enhanced, and the particle quality is significantly improved.
4. Plastic film pelletizing line is mainly composed of crushing dry cleaning machine, extruder and automatic traction pelletizer. Automatic feeding, automatic temperature control, automatic dust removal, impurity removal, automatic filter change, no pollution in the production process.

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
