SJW CO-KNEADERS -- Compounding Expert

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. Click here to know more about the working principle of Co-Kneader.
