What are the reasons for the abrasion of screw extruder in cable equipment?

The abnormal wear of screw and barrel will occur when the screw ring knot and foreign matter jam. Ring knot means that the screw is locked by the condensed material. If the screw extruder lacks a good protection device, the strong driving force may twist the screw and jam, which will produce extraordinary huge resistance, causing serious damage to the screw surface and serious scratch of barrel, and the scratch of barrel is difficult to repair . In principle, the barrel is designed to have a longer service life than the screw. Generally, the normal wear of the barrel is not repaired. The screw thread is often repaired to restore the radial clearance between the barrel and the outer diameter of the screw.
