LDPE film pelletizer machine adopts the principle of extrusion dehydration.After cleaning the plastic film (plastic film, plastic agricultural film mulch, PP woven bag, snakeskin bag, space bag, ton bag, thin plastic sheet waste plastic), quickly A device that squeezes water out of plastic.
LDPE film pelletizer machine adopts the principle of extrusion dehydration. After cleaning the plastic film (plastic film, plastic agricultural film mulch, PP woven bag, snakeskin bag, space bag, ton bag, thin plastic sheet waste plastic), quickly A device that squeezes water out of plastic. Equipped with rotating screw device and hard tooth surface reducer, it can squeeze and dehydrate plastic film, plastic agricultural film, mulch film, PP woven bag, snakeskin bag, space bag, ton bag, thin plastic sheet, waste plastic, etc. of fully automatic equipment.
The extruded water flows out from the mesh holes, and the material is extruded and rubbed with high strength to generate heat, and then dispersed into the granulator or squeezed out of the water and directly extruded into semi-melted irregular particles. After granulation, it is directly shaped after being diced by a blade. After crushing, the plastic film is squeezed and dehydrated by the granulator. The dehydration efficiency is fast, the effect is good, and the machine is easy to operate.
1. The screw and barrel of the pelletizing line are made of 38CrMoAl material, and the surface is nitriding and hardening, which has a long service life.
2. LDPE film pelletizer machine gearbox adopts a hard-tooth surface oil-cooled gearbox, which is half the weight of the soft-tooth gearbox, wear-resistant, has a service life of 3 to 4 times, and a bearing capacity of 8 to 10 times.
3. After the granulation line is discharged, the water ring is directly cut into granules, dehydrated by the dehydrator, and the appropriate particles are sorted by the vibrating screen and then sent to the storage bin by the fan.
4. There are drainage ports and vacuum pumps 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
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.
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.
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
