SKW 105 Series Co-kneader

Advantages of the XINDA  SKW105 Co-Kneader:

• Lower energy input, lower melt temperatures.
• Extremely homogeneous mixing, no shear spikes, equal treatment of polymer matrix.

Working Principles:

The Co-Kneader, a mild-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 provides dispersive and distributive mixing simultaneously.

Axially opened split barrel guarantees ease of cleaning. Those splined, segmented screw elements and pins can be changed easily according to different processing techniques. In addition, some pins are hollow inside, allowing thermocouples to be inserted to get the accurate temperature of the materials inside the barrels, so as to enable liquid additive injection. Different from other extruders, the kneading process is achieved radially and axially at the same time. All in all, the Co-Kneader has outstanding kneading, mixing efficiency, and a high degree of self-wiping. It is the most suitable for compounding purposes.
