Four-flight Compounding System
Based on 3-flgiht compounding design, XINDA develops latest new technology with 4 flights. The XINDA SKW Kneader each spiral is broken by four gaps per revolution to locate the kneading flights. Four rows of kneading pins, which are individually inserted in the barrel per 90 degree, are intermeshed with these flights. With the same L/D ratio, it achieves more mixing, but less friction heat. The reciprocating wobble-box synchronizes the shaft rotation and oscillation so that each revolution of the screw is accompanied by one full stroke forward and backwards. This ensures optimal distributive and dispersive mixing with minimal energy consumption.
