Product Description

China Supplier Single Screw Design Plastic PP PE Film Recycling Pelletizer

Product Description

We have a dedicated single screw pelletizing line for soft plastic film . The pelletizing process consists of compacting feeding, main screw plasticizing, screen changer filtration, second stage plasticizing, water-ring pelletizing, dewatering and collection.
Output from 200kg/hr up to 1000kg/hr.
Suitable for specialized plastic recycling plants and pelletizing plants, the equipment has many advantages such as low energy consumption, stable output, easy maintenance, long service life and cost-effectiveness.

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.
The final product will be in pellet form and can be placed directly into the production line for blowing film, tube extrusion and injection molding.

Single Stage Pelletizing Line Process flow:
Belt conveyor→ Metal detector →Film Agglomerator /Compactor →Single screw extruder →Hydraulic filer changer→ Die head →Water ring cutting →Dewatering machine→Vibrator→ Air dryer Blowing system→ Storage hopper→ Finished product packing.

Double Stage Pelletizing Line Process flow:
Belt conveyor→ Metal detector →Film Agglomerator /Compactor →1# Single screw extruder →1# Hydraulic filer changer→2# Single screw extruder →2# Hydraulic filer changer→ Die head →Water ring cutting →Dewatering machine→Vibrator→ Air dryer Blowing system→ Storage hopper→ Finished product packing.

Detailed Photos

 

1.Belt conveyor

(1)Belt conveyor as standard feeding device for plastic film, raffia, filament, woven bag, nonwoven fabric, etc.
(2)Metal detector can be installed on conveyor as optional item, Detecting and separating the metal to protect the compactor and extruder effectively.

2.Compactor

(1)With optimal design of rotary blades and stationary blades.
(2)The material got cutting, mixing and compacting in the compactor uniformly, to ensure the material heated and dried effectively which guarantee a fast and stable feeding from the compactor into the extruder.

3.Extruder

(1)A specialized single screw extruder applied to gently melt the pre-compacted material. 
(2)The plastic scraps will be well melted, plasticized in the extruder. 
(3)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.Hydraulic screen changer & Extrusion mould

(1)Structure: Plate and double stations
(2)Temperature control zone:2zones  
(3)Pressure: 0-15MPa
(4)Material of mould: 38CrMoAIA
(5)Heating processing: Nitrogen treatment
(6)Hardness HV850-950,depth: 0.4-0.7mm

5.Horizontal cutting machine

Material of blade: K2

 

6.Dewatering Device

(1)This drying system can get final pellet humudity less than 1%.
(2)Horizontal design of dewaterer with small floor area.

7.Silo

(1)The function of the blower is to transport particles to the silo through stainless steel pipes.
(2)Pipes and silos are wrapped
with black sound insulation cotton, which reduces the volume from 82dB to 68dB.
(3)New design makes it easier to operate.
