Co-rotating twin-screw kneader


Co-rotating twin-screw kneader
ZK 25(42 D)

The twin-screw kneaders have the task of conveying, compacting, plastifying and homogenizing plastics materials (in granule and powder form), fed via a hopper/dosing unit, and to feed these to a die (mould) for further forming.

The twin-screw kneader serves to manufacture test specimens and to evaluate the material processing properties.

Special Features:
• Hinged C-flanges for easy dismantling
• Motorized axial barrel movement (optional)
• Configurable for co-rotating operation
• Configurable for counter-rotating operation
• Configurable for high throughput
