Four Flights Co-kneader HFFR Compound Extruder System

Based on 3-flight compounding design, XINDA develops the 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 degrees, 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.

Working Principle

Strengths of 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
