HDPE film pelletizing line cleaning granulator, mainly dealing with plastic film recycling, granulation and reuse. Film pelletizing line mainly include agricultural film, mulch film, packaging film, woven bags, ton bags, etc. Waste films are generally dirty, and impurities should be removed and cleaned during recycling. The main method of recycling is granulation, which is cleaned and dried. After pelleting, it can be returned to the furnace as fuel or remade into plastic products, turning the waste film into a recyclable raw material.
HDPE film pelletizing line forced feeding device, host and pelletizer of the pelletizing line are all controlled by frequency converters; the screw and barrel of the pelletizing line are made of 38CrMoAl material, and the surface is nitrided and hardened, which has a long service life; the gear box of the pelletizing line is made of hard Gear box with oil cooling on tooth surface, the weight is half lighter than that of soft tooth gear box, wear-resistant, 3~4 times of service life, 8~10 times of bearing capacity; the pelletizing line is directly water-ring cut pellets after discharging, and the dehydrator After dehydration, the appropriate particles are sorted by vibrating screen and sent to the storage bin by the fan. There is a drain and a vacuum pump on the barrel of the granulation line to drain and exhaust to ensure the quality of the particles.

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
