High yield triple screw plastic extruder 

Co-Rotating triple screw extruder is the reinforced type of twin screw extruder, which suitable for material which is high requirement for mixing dispersion effect. It is mainly application to black masterbatch, high filling etc. It has the advantages of high capacity and low energy consumption.

1. Electric control system of Three screw extruder
2.The Gearbox
3.Mixing and Feeding system
4.The compounding system
5. pelletizing system

Main Features
Three screw construction with parallel diamater in same direction.
High shear efficiency and good plasticizing effect.
Good practice and dispersal effect.
High output and low energy consumption.
Good exhaust performance.

Detailed Images
1. Name: three Screw
The screw elements material is W6Mo5Cr4V2
The core axis is made of high quality alloy steel 40CrNiMo

2. Name: Gearbox
Parallel tri-axial structure is combination of reduction and matrix. The gear is made of high quality alloy (20CrNi2Mo).Drive bearing:
Lubrication: Gear bearings in the gear box will be of oil immersed. There is hydraulic lubrication in the gear engagement and gear bearings.
Cooling: Lubricated cooling adopts shell and tube cooler and circulated water cooling method.
 

3. Name: Barrel

Standard: L/D: 40:1, and other available
Length: 10 sections for 40:1, 10*240mm=2400mm
Material: made of 45# forged steel with the abrasion-resistant alloy 101(Ni-Fe-Cr-W) inside, which is smooth and abrasion resistant. The hardness is HRC60-64

Pelletizing methods
1. Water cooling strand pelletzing
2. Air cooling pelletizing
3. Water ring pelletizing
4. Under water pelletizing

Application
1. High dispersibility, high filling capacity, such as modification of polyolefin, modification of engineering plastics,etc.
2. Mixing, venting and devolatilization, and homogeneous residence time for high reactive extrusion, such as XLPE cable,silance crosslinking cable, TPE,etc.
3. High concentration of masterbatch and other functional masterbatches with high dispersing effect, such as high concentration black,white materbatch, highly filled flame retardant, semiconductive material,etc.
4. In-line compounding molding of film, board and injection parts, such as breathable film, long glass fiber reinforced plastic structrural parts.
