HDPE Film Granulation System

HDPE film granulation system is specially designed by Purui Machinery Company and is mainly used for the recycling granulation of packaging film, printing film and food packaging film.

HDPE Film Granulation System Description:

HDPE film granulation system is specially designed by Purui Machinery Company and is mainly used for the recycling granulation of packaging film, printing film and food packaging film.
Among them, the compactor is equipped with a cutter head and a fixed knife on the inner wall, which are used to cut and break the BOPP film, and generate heat under the high-speed cutting friction to make the material shrink by heat, increase the bulk density and increase the feeding amount, and the heat-shrinked material passes through the inner wall. The deflector is thrown into the host screw.
The granulation method of BOPP film recycling automatic granulation unit is water ring granulation, and the granules are in the shape of round tablets. Compared with the traditional strip granulation method, the water ring granulation cuts the granules of uniform size and does not need to change the screen. The problem of broken bars, the equipment occupies less space and other advantages.

HDPE Film Granulation System

Film Granulation System Applications:

1. HDPE film granulation system capacity of the plastic granulation unit is between 100-1000 kg/hour.
2. The parts in contact with the material are made of SUS304 with a thickness of more than 3 mm to ensure a long service life.
3. The world-renowned brand components used in the granulation production line – SKF bearing, Siemens contactor, ABB inverter, Siemens PLC control.

Film Granulation System Work Process:

Plastic → Belt Conveyor → Metal Detector (Optional) → Compactor / Compactor → Extrusion → Hydraulic Screen Change → Die Head → Cooling Water Tank → Centrifugal Dehydrator / Dewatering Vibrating Screen → Dewatering Fan → Storage Silo

HDPE Film Granulation System Detail:

  • 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

  • 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.
