HDPE film granulating machine is applicable to all kinds of films and woven bags with high toughness and thickness of about 1-25mm.
HDPE film granulating machine is applicable to all kinds of films and woven bags with high toughness and thickness of about 1-25mm. The production line covers: conveyor, crusher, friction cleaning machine, separation sedimentation tank, squeeze dryer, granulator, etc.
The production line is suitable for all kinds of plastic films, woven bags and ton bags with sediment content up to 80%. The whole line is under automatic control, and the system units operate jointly. It has the function of predicting possible abnormal conditions while realizing production capacity. The final product of the production line is plastic particles with good quality and high output.
1. HDPE film granulating machine has a good effect on the problems of large water content and many impurities in materials;
2. As both machines of the parent-child granulation unit are equipped with exhaust devices and screen changing filter devices, the gas generated after material heating can be discharged for many times, and the impurities of the material can be filtered out after two times of filtration, so that the produced particles are more solid, smooth and pure.
3. The hydraulic lifting of die head can make the main machine change the filter screen without stopping the machine and improve the production efficiency.
4. Reduction gearbox: high torque design; No noise, stable and smooth operation.
5. The special screw cylinder design makes the mixing effect better and the dispersion better, and effectively improves the problems of black spots and color difference.
6. The forced feeding device and oil pressure quick change screen device can be selected according to the particularity of the material, so that the production capacity is higher and the power consumption is less.

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
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.
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.
