Four-flight Compounding System(SKW type)
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.
Strength:
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
XINDA SKW co-kneader:Higher speed; bigger capacity; better mixing, lower energy consumption.
