Conical twin screw and barrel is the very kind of screw specialized in direct extrusion of various types PVC powder. With the unique advantage of screw core cooling, vacuum exhausting, good seld cleaning, easy laying off, easy maintenance and low energy consumption, conical twin screw and barrel can meet the technical requirement of material delivery, compression, mixing, exhausting and plasticization at a lower temperature. As a result, it gradually took replace single screw equipment in PVC field and was already broadly applied in PVC processing fields.
However, the increase of CaCO3 proportion when processing PVC products and appearance of new type of PVC material, led to the result of deficiency in anticorrosion, wear resistance, plasticization quality and output of conical twin screw and barrel. According to the clients different requirement, Yumin engineer designed the best configured screw by introducing the most advanced design concept of twin screw thread, twin screw depth and twin conicity to achieve the best plasticization status and the biggest output. Yumin engineer also introduce the internationally advanced heat treatment equipments and technology to solve the problem of wear and corrosion of conical screw and barrel. Conical twin screw and barrel is already successfully applied in the precess of PVC sheet, pipe, sheet, pellet and mould, etc. What's more, it has successfully solved the technical problem of various low foaming, high foaming, wear and corrosion and so on.
