SKW XINDA Type Cascade Four Flights Co-Kneader Compound Extruder for High Filled Master batch
The XINDA SKW Four flights compouding system,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.

Advantages of the XINDA Co-kneader

The Co-Kneader, a mild-shear rotating and reciprocating single-screw extruder, is designed for shear and temperature sensitive compounds. The flights on the screw are interrupted and interqct with three rows of stationarv kneadina pins located in the barrel wall. The interaction between the moving flights and the stationary pins provide dispersive and distributive mixing simultaneously. Axially opened split barrel guarantees ease of cleaning. Those splined, segmented screw elements and pins can be changed easily according to different processing techniques. In addition, some pins are hollow inside, thermocouples can be inserted to get the accu- rate temperature of the materials inside the barrels, so as to liquid additives injection. Different from other extruders, the kneading process is achieved radially and axially at the same time. All in all, Co-Kneader has outstanding kneading, mixing efficiency and high degree of self-wiping. It is the most suitable for compounding purposes.

Plastic Extruder High filled Master batch Compounding Line Making Granules With Gravimetric System
Four-flight Compounding System(SKW type) Based on 3-fight compounding design, XINDA develops latest new technology with 4 fights. The XINDA SKW 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.

 

Advantage of the compounding system:
--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
Feature for SKW Co-kneader:High speed,Bigger capacity,Better mixing,Lower energy consumption
