HDPE Film Granulation Line

HDPE film granulation line is a recycling and granulating unit for low-density polyethylene (LDPE) and high-density polyethylene (HDPE) plastics.

HDPE Film Granulation Line Description:

HDPE film granulation line is a recycling and granulating unit for low-density polyethylene (LDPE) and high-density polyethylene (HDPE) plastics. The specially designed screw structure and exhaust port can effectively eliminate the moisture and volatile gas generated in the process of material melting, and the extruded particles are uniform, solid, beautiful and with high production efficiency.

The pelletizing method of the unit is that the plastic is extruded in the melt state, scraped off by the blade and solidified by circulating cold cutting and water-cooling cutting. After dehydration by the high-speed dehydrator, the moisture of the finished particles can be effectively removed. The drying effect is good, the pelletizing process is simple to operate, with a high degree of automation, no dust, low noise, good slicing quality and beautiful appearance.

HDPE Film Granulation Line

Film Granulation Line Applications:

1. Film granulation line has a high degree of automation. It is a full-automatic assembly line. As long as someone adds waste plastics in front and connects granular finished products in the back, the direct transformation from waste plastics to granular finished products is realized;

2. Film granulation line is continuously improved on the basis of German equipment drawings, with reasonable design, beautiful appearance and durability. The parts in contact with materials are made of stainless steel;

3. The particles made are of high quality, free of bubbles, full and round;

4. The shape of the particles is beautiful, the shape is a cylinder, and the size and thickness can be adjusted;

Film Granulation Line 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 Line Detail:

  • 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
