Detailed Product Description

Working principles:
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 reciprocate 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:
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) Equipments are reliable and durable
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
