Compounding Extruder / BUSS Design Co-Kneader

The SJW reciprocating kneading and extruding system is different from traditional
single or twin screw extruders because of its unique working principles The spiral
of the screw is detached three times at the circumference and forms the so-called
kneading screw In those gaps are the stationary kneading pins, which are
fixed inside the kneading casing while the screw is circumrotating once, the axis
is also moving reciprocatively once due to such specific moments, the material
is not only sheared between the pins and kneading flights, but also inverted.
This working process is totally different from traditional single or twin screw
extruders It improves the effectiveness of kneading by moving transversely and
lengthways, hence it can provide high-quality dispersive and distributive mixing.
In addition, by using suitable breechblock, the pressure is relatively steady
With circular water cooling system both inside the barrels and screw, the processing
temperature is controlled accurately and much lower than the other machines
because the materials are processed while they are intenerated, not completely
melted Accordingly, there will be less material degraded and the quality of the
final products will be the best.

Advantages of Xinda reciprocating kneading and extruding system:
1) Board applications for compounding without changing hardware
2) Axially opened split barrel guarantees ease of cleaning and fast product changes
3) Efficient blending of liquid components
4) Consistent product quality and good reproducibility
5) High degree of self-wiping
6) Reliable and durable equipment
7) Lower processing temperature in comparison with other system
8) A reciprocating screw shaft provides outstanding dispersive and distributive mixing
9) Accurate temperature control, uniform gentle shear for the products, shorter L/D
10) Wear parts, such as screws, barrel lining and pins can be changed individually
11) Low maintenance cost.
