Applications:
PP PE Plastic Film Woven Bag Plastic Granulating Line is double stage plastic regenerative pelletizer, which is suitable for many kinds of plastic waste materials recycling and making pellets, such as PE, HDPE, LDPE, PP, BOPP plastic film, bag,fiber,rope scrap material and etc. The film can be pressed in the compressor and then be pelletized.
1.Applicable plastic materials: PE, HDPE, LDPE, PP, BOPP, PET, PA/Nylon, etc.
2.Material shapes: film, bag,fiber,rope scrap.
3.Material types: rolls, loose, bundled.
4.Material comes from offcut, industry defective materials, washed materials and printed materials.
Note: depending on different material properties, various downstream equipments are needed.
Description:
This water-cooling single screw plastic pellet making machine is one stage plastic regenerative pelletizer, which is suitable for many kinds plastic waste materials recycling and making pellet, such as PP, HDPE, LDPE, LLDPE Film and clean woven/nonwoven bag materials, etc. The film can be pressed in compressor and then be pelletized.
Process flow:
Conveying feeding→ Metal detector →Film Agglomerator /Compactor →Degassing single screw extruder →Hydraulic filer exchanger→ Mould head →water ring cutting →Dewatering machine→ Air dryer Blowing system→ Storage hoper→ Finished product packing.
Feeding type: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 control system, to warn and stop the system, in case that
metal is found in feeding section
2. 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.3. Vacuum Degassing Extruder
A specialized single screw extruder applied to gently melt the pre-compacted material.
The plastic scraps will be well melted, plasticized in the first stage extruder, and the
plastic will be extrude by the second stage extruder. 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 some water content.4. Piston Filters with Large Filtration Area:
Very large filtration area,up to 3,000 cm² for standard products,and larger ones
up to 10,000 cm² model are also available
Reducing screen changing frequency,improved productivity
Built-in static mixer improving product stability
Superior sealing system completely eliminating polymer leakage
Very low operation cost5. Water ring pelletizing system:
Adjust the pelletizer speed automatically based on the pressure of Die head, and
achieve the uniform final pellets size.
Pneumatic blade clamping device: knife of pelletizing system compact with Die head
automatically by pneumatic system, in order to achieve 100% contact between the
blade and the pelletizing template , enhanced concentricity of blade, and slow its
abrasion time.
