LDPE Film Granulation Line Description:

LDPE film granulation line is a kind of model for double order formula mother pull granulator, has the characteristics of simple structure, easy maintenance, low energy consumption, high output, mainly suitable for PE/PP film material, pipe crushing material recovery granulation, do not need two plasticizing and multiple exhaust and filtration of raw material extrusion granulation. Often used in modified granulation, clean plastic recycling or scrap recycling processing.
Film granulation line can also be divided into single screw strip granulator, single screw water ring granulator according to different granulation methods.

LDPE Film Granulation Line

LDPE Film Granulation Line Applications:

1. LDPE film granulation line uses STMATIC S7-200 programmable logic controller (PLC) produced by SIEMENS to control the whole system.
2. The main low-voltage electrical components of the system are Siemens products to ensure the reliable operation of the system.
3. The system has a variety of chain protection functions, can effectively eliminate the adverse consequences caused by the wrong action.
4. Squeeze dry dehydration principle, to solve the traditional membrane or filamentous plastic dehydration difficult problem.
5. Mmechanical extrusion dehydration, compared with the original hot air drying, great energy saving.
6. Special reducer structure, special screw design, special extrusion principle, can be continuous production.
7. After extrusion, the material directly into 3-5cm irregular coarse granular.
8. Squeeze dry effect is good: ensure about 90%
9. The system has good scalability, according to user requirements, can provide further services.

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

LDPE Film Granulating Line 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

  • 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.
