​

two stage single screw extruder (mother and baby extruder)
Application:

ML/SJ double stages single screw recycling and granulation unit
It is used in the PE, PP, PS, PA film and silk, fabric recycling and granulation
The material is comparatively dirty with much impurity and high water content (more than 5%)
The output is 100-1500kg/hour
The machine is made up of two kinds screw
 
Advantages:
Compactor can do the material cutting, pre-dried, pre-heated and compacted in the shredder drum
Material can be processed directly without the pre-cutting work
It is especially suitable for the film with high impurity and high moisture content
Two stage single screw extruder is better for the degassing with linked part, degassing hole
Once you need, we also can equip two layer cutters board in the compactor
Power consumption: 0.27kW/kg to 0.3kW/kg
Labor: two people one line
 
Work process:
 
Feeding is automatic according to customer requirements, in the patented
Cutter compactor the material is cut, mixed, heated, dried, densified and buffered: the tangentially connected extruder is filled continuously
Extruder screw the material is extruded
In the degassing zone: the air and water and more is volatilized, the material is extruded to the die
Pelletizer

​

Purui  sheet recycling extruder, granulator, plastic waste processing machinery, plastic recycling system 
Applicable plastic materials: PP, HDPE, LDPE,  LLDPE, TPV, ABS and PS
Material shapes: film, bag and flake
Material types: woven bag, printed LDPE film, film (rolls, loose, bundled) waste agriculture film, foamed plastics (EPS) and raffia

Features of film/flake granulating plastic recycling machine:
Filter before vacuum system achieves better degassing and filtering effect
Material is cut, pre-dried, pre-heated, pre-homogenized and compacted in the shredding drum
Various materials can be processed directly without need of the upstream pre-shredding, resulting in a dramatic reduction in operational costs
Less power consumption cost per kilogram (film: 0.39kW/kg, flake: 0.35kW/kg), high throughput, reduced floor space occupation and operator attendance

How it works:
Screw charger uploading material by timer
Feeder and extruder is controlled by inverter
Various L/D for Various material
Natures degassing, vacuums degassing adopting for moisture
Water ring die face cutting for perfect pellets shape
