Co-Kneader

most suitable for compounding,like PVC compounds,filling ,blending,color master batches, wire and cable compounds,powder coating

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 circumferenceand 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 thematerials 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 mixing9) Accurate temperature control, uniform gentle shear for the products, shorter L/D10) Wear parts, such as screws, barrel lining and pins can be changed individually11) Low maintenance cost.Models:1) SJW-45: 45mm, 60-100kg/h output2) SJW-70: 70mm, 150-250kg/h output3) SJW-100: 100mm, 200-650kg/h output4) SJW-140: 140mm, 400-1000kg/h output5) SJW-200: 200mm, 1200-3,500kg/h outputPacking:Wooden box
