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.


Advantage of XINDA Co-kneader

Lower energy input, lower melt temperatures

Extremely homogeneous mixing, no shear spikes, equal treatment of polymer matrix

High degree of self-wiping and have no dead spot

Dispersive mixing without destroying delicate fillers

High volumetric loadings of fillers and additives

Efficient blending of liquid components

Broad application for compounding without changing hardware

Axially opened split barrel guarantees ease of cleaning and fast maintenance

Replacement parts, such as screws, barrel lining and pins can be changed individually
