Repair Methods for Screws and Barrels
1.1 Thermal Spraying Repair Thermal spraying offers surface strengthening for repairs, characterized by high-quality wear-resistant coatings, low cost, high efficiency, and wide applicability. Its basic process involves: melting spraying materials (metals, ceramics, plastics, etc.) into a liquid or molten state, refining them into particles ranging from tens to hundreds of microns, and spraying these particles […]
Main causes and solutions of screw extruder wear
Main cause of wear of the screw extruder The normal wear of the screw and cylinder of the screw extruder mainly occurs in the feeding area and the metering area. The main wear reason is caused by the dry friction between the slice particles and the metal surface, and the wear is reduced. Screw and […]
