HDPE film pelletizing equipment is applicable to PE, HDPE, LDPE, LLDPE, etc., and is completed at one time from feeding, crushing, conveying and granulation.
HDPE film pelletizing equipment is mainly composed of conveyor belt, chamber machine, single screw extruder, hydraulic screen changer, water ring pelletizing system, chute, dehydrator, vibrating screen, air conveying system and silo. Plastic film granulator has the characteristics of crushing, extrusion and granulation, with high efficiency and high output. The plastic film granulation production line is applicable to PE, HDPE, LDPE, LLDPE, etc., and is completed at one time from feeding, crushing, conveying and granulation. The extruder can select exhaust hole or no exhaust hole according to the characteristics of the material. The granulation method adopts water ring grinding and hot cutting, which can be configured according to the needs of users. The single board double station screen changing device has no shutdown and large filtering area.
1. HDPE film pelletizing equipment used for recycling and granulation of LDPE and HDPE hard wastes.
2. Round particles, similar in shape to new particles.
3. Vibrating screen can be used according to customer requirements.
4. Water ring granulation can avoid strand problems.

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
