SK63 Twin Screw Extruder

Overview of SK63 Twin Screw Extruder


SK63 twin screw extruder can be used in filling masterbatch, engineering plastics, color masterbatch, functional masterbatch, blending modification and other industries. In order to adapt to the operation of filling master batch, SK63 Twin Screw Extruder mainly considers the following points: a. HIP hot isostatic pressing technology material is used in the material selection of cylinder and screw, which has the advantages of high wear resistance. It is suggested to use high wear resistant material (SAM10). At the same time, in view of the problem of feeding a large amount of powder in the process of high filling, the side feeder can be used for forced feeding. A number of weightlessness metering feeding scales are equipped to ensure the accuracy of the formula.

For the filling operation of inorganic materials with low bulk density and large filling, such as CaCo3, Talc, and Titanium dioxide, Nanjing KY Chemical Machinery Co., Ltd. can choose the lateral enhanced feeding technology (FET technology), which removes the gas in the feeding material by negative pressure suction while feeding side, and uses special filtering technology equipment to prevent the inorganic powder from being extracted. SK63 twin screw extruder performs excellently. The bulk density of raw materials has been increased and the lateral feeding quantity has been greatly increased to increase the total output of the equipment.
