Compounding Extruder
The SJW reciprocating kneading and extruding system is different from traditionalsingle or twin screw extruders because of its unique working principles The spiralof the screw is detached three times at the circumference and forms the so-calledkneading screw In those gaps are the stationary kneading pins, which arefixed inside the kneading casing While the screw is circumrotating once, the axisis also moving reciprocatively once due to such specific moments, the materialis not only sheared between the pins and kneading flights, but also inverted.This working process is totally different from traditional single or twin screwextruders It improves the effectiveness of kneading by moving transversely andlengthways, hence it can provide high-quality dispersive and distributive mixing.In addition, by using suitable breechblock, the pressure is relatively steadyWith circular water cooling system both inside the barrels and screw, the processingtemperature is controlled accurately and much lower than the other machinesbecause the materials are processed while they are intenerated, not completelymelted Accordingly, there will be less material degraded and the quality of thefinal products will be the best.Advantages of Xinda reciprocating kneading and extruding system:1) Board applications for compounding without changing hardware2) Axially opened split barrel guarantees ease of cleaning and fast product changes3) Efficient blending of liquid components4) Consistent product quality and good reproducibility5) High degree of self-wiping6) Reliable and durable equipment7) Lower processing temperature in comparison with other system8) 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 cost12) BUSS design co-kneader (lab use)13) Widely used as lab application and small quantity production purpose14) PLC controlInner packing:Wood boxes
