Supply Beijing 20KW extruder electromagnetic heater manufacturers extruder uses: Extruder plastic processing machinery is an important device, it is not only suitable for extrusion molding and mixing polymer materials processing, its use has been widened to food, feed, electrodes, building materials, packaging, paper pulp, ceramics, and other fields, mainly used in machinery. Extruder speed, high-yield, lower investment allows investors to obtain greater output and high returns. However, the speed of the extruder screw speed also brings a series to overcome the difficulties: such as the residence time of the material in the screw reduction will lead to uneven mixing plastics materials, the material is subjected to excessive shear can cause abrupt temperature materials and thermal decomposition, extrusion stability control will cause difficulties in the extrudate geometry fluctuations, accuracy related auxiliary equipment and control systems must be improved, increased wear of the screw and barrel require high wear resistance and high wear material, reducer How to improve the bearing in the case of high-speed operation of its life and other issues need to be resolved.
