Double Stage HDPE LDPE LLDPE Film Recycling Pelletizing Line

Double Stage HDPE LDPE LLDPE Film Recycling Pelletizing Line

RETECH Machinery is specializes in R&D and production of double stage HDPE LDPE LLDPE film recycling pelletizing line.

Double Stage Film Recycling Pelletizing Line Description:

1.High efficiency

Compared with the primary designs,the output capacity of RETECH RT series new generation PP PE film pelletizing machine could be increased 20%.

2.Low power consumption

The power consumption reduced about 15% compared with the primary design.

3.Highly automatically

Only 1-2 people needed for one plastic film granulating line.

Double Stage Film Recycling Pelletizing Line Application:

Applicable plastic materials: PE,HDPE,LDPE,LLDPE,PP,BOPP,PET,PA,EPE,etc
Material shapes: film, bag, non woven fabric, crushed material(PE/PP)
Material types: (rolls, loose, bundled)
Material comes from offcut,defective film and washed clean film.
Note: depending on different material properties, we could design customised recycling pelletizing solutions.

Double Stage PP PE HDPE LDPE Film Recycling Pelletizing Machine Technical Parameter:

Double Stage Film Recycling Pelletizing Machine Working Procedure:

PP PE film→Belt conveyor→Compactor→Mother extruder →Hydraulic screen exchanger →Baby extruder→Hydraulic screen exchanger →Die face cutting system →Air transmission →Silo storage

Feed offcut PP PE film on the Belt conveyor machine and send into Compactor for cutting, heating, compacting and mixing, then enter the extruder for extruding.

Feed regrind material through the Spiral charger and Feeder on the extruder.

Instruction: the film and regrind material can be recycled separately or together, depending on customers’ different needs.

Double Stage Film Recycling Pelletizing Machine Detail:

Belt Conveyor:
As our standard design, plastic scraps such as film, filament, raffias conveying 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.

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.

Degassing 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.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.
