A Conical twin screw barrel is used for extruding plastic materials. The screw clearance is an important parameter that must be considered when purchasing a barrel. If it is too small or too large, the product shear rate will be low and the plasticizing effect will be poor. Moreover, the material will have a long residence time in the barrel, which will cause easy burning of the product.
A conical twin screw barrel is widely used in the processing of PVC products. The conical twin screw barrels has high output and long service life. They also feature improved mixing and homogeneity. Their screw geometry has been optimized to meet the unique requirements of various PVC material formulations.
The screw is used for filling, blending, modifying, reinforcement, and other applications. It is also widely used for dehydration treatment of chlorinated polypropylene and super absorbent resin. It can also be used to produce carbon powder, magnetic powder, and other insulation materials. Small models are mostly used for scientific research.
