Four Flights Co-Kneader HFFR Compound Extruder System

Four Flights Co-Kneader HFFR Compound extruder System

Based on 3-fight compounding design, XINDA develops latest new technology with 4 fights. The XINDASKW Kneader each spiralis broken by four gaps per revolution to locate the kneading fights. Four rowsofkneading pins, which are individually inserted in the barrel per 90 degree, are intermeshed with theseflights. 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 accompaniedby one full stroke forward and backwards. This ensures optimal distributive and dispersive mixing withminimal energy consumption.

Working Principle

Strength for 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 fllers
• High volumetric loadings of fllers 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
