CO-KNEADERS ——Compounding Expert

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.

Co-Kneader is different from traditional single or twin screw extruders because of its unique mechanisms. The spiral of the kneading screw is detached three times at the circumference. In those gaps are the stationary kneading pins, which are fixed inside the kneading case. While the screw is circumrotate, so too does the axis, moving reciprocally.

Other Application

--client comments

Bigger output leads to lower manufacturing cost. In addition, one whole line with max two workers helps save much labor cost. Excellent performance of the whole line. We install the whole line by ourselves with online support from Xinda team. Some key words to describe this line: bigger output, better dispersion, lower shear, and less manufacturing cost.

Project Introduction

By using Xinda SJW-45 and SKW-125 Co Kneader for 3 years, this customer occupied HFFR cable compounds market in American region in a short time. Responding to big demanding, in 2021, they purchased one bigger model SKW-140 Co kneader, which can achieve HFFR output around 2400kg/h. This line is designed as fully automatic, from Material handling system, Gravimetric feeding system, Co kneader, Eccentric water ring cutting system till Packing and sealing.
