HDPE film pelletizing machine breaking materials, the unqualified film thickness and the leftover materials from the edge cutting produced in the co extrusion process need to be recycled online to realize recycling.
HDPE film pelletizing machine breaking materials, the unqualified film thickness and the leftover materials from the edge cutting produced in the co extrusion process need to be recycled online to realize recycling.
Purui machinery has designed a targeted granulation equipment for the heat shrinkability of HDPE film pelletizing machine and the stability after coextrusion. The problem of changing the color and molecular structure of the material in the recycling granulation is successfully avoided, and the recovery with high utilization rate is realized.
Crushing – extruding – pelletizing, three in one design;
HDPE film pelletizing machine cutting design of the new compactor increases the capacity by 30%, which is more efficient and energy-saving;
The screw is specially designed to perfectly match the extrusion rate and plasticization; Energy efficiency ratio up to 0.22kw/kg
It ensures that the original molecular structure and physical properties of materials are not changed while ensuring high production.

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.
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
Electric control system
One button “START”,One button “STOP”, lEmergency Stop. lProtection switch. Every operation position and rotary parts are equipped with limit switches for safety protection. lPrecise temperature control, optimized plasticization design, ensure reliable quality of granules. lProtection from over-heat in the compactor.
