Compounding Extruder/BUSS Design Co-Kneader

Low shear, low pressure, low temperature but high kneading efficiency for your compounding needs.

The Co-Kneader, a low-shear rotating and reciprocating single-screw extruder is designed for shear and temperature sensitive compounds. The flights on the screw are interrupted and interact with three rows of stationary kneading pins located in the barrel wall. The interaction between the moving flights and the stationary pins provide dispersive and distributive mixing simultaneously..

Advantages of the Xinda Co-Kneader:
1. Lower energy input, lower melt temperatures.
2. Extremely homogenous mixing, no shear spikes, equal treatment of polymer matrix.
3. High degree of self-wiping and have no dead spot.
4. Dispersive mixing without destroying delicate fillers.
5. High volumetric loadings of fillers and additives.
6. Efficient blending of liquid components.
7. Broad application for compounding without changing hardware.
8. Axially opened split barrel guarantees ease of cleaning and fast maintenance.
9. Replacement parts, such as screws, barrel lining and pins can be changed individually.
