Extrusion roller sleeve of roller press

Abstract

The invention provides an extrusion roller sleeve of a roller press. The extrusion roller sleeve comprises an extrusion roller sleeve and is characterized in that a plurality of grooves are formed inthe outer surface of the extrusion roller sleeve in a uniform distribution mode, and wear-resistant materials which are higher 1-10mm than the surface of a roller body are welded in the grooves, suchas ZD310 or ZD903 wear-resistant flux-cored wires developed by Zhengzhou Research Institute of Mechanical Engineering Co., Ltd, and SKC A43-O wear-resistant flux-cored wires or other surfacing materials with high wear resistance developed by Voestalpine Bohler Welding Co., Ltd. The extrusion roller with the structure combines the advantages of the surfacing extrusion roller and an insert pin typeextrusion roller, so that the risk that a pattern layer is broken away from a roller body is reduced, and the problem that column nails are separated from the roller body is solved. Meanwhile, a basemetal between weld joints forms a trend of delaying downward abrasion of a material cushion after being worn to a certain degree, and the service life of the roller body is effectively prolonged.

Description

technical field [0001] The invention relates to an extrusion crushing roller for crushing hard materials by extrusion, which belongs to the technical field of engineering equipment, and in particular relates to an extrusion roller sleeve of a roller press. Background technique [0002] Roller press is a new type of high-efficiency and energy-saving powder equipment. It crushes materials through high-stress extrusion. Due to its high efficiency and energy saving, it presents unique advantages and prospects in cement, metallurgy, ore and other crushing industries. When the extrusion roller is crushing ore, cement clinker and other materials, the roller surface is subjected to severe high-stress abrasive wear, plowing wear and fatigue damage, so the wear resistance and service life of the extrusion roller surface have become the characteristics of the roller pressure. The key technical indicators of such equipment. [0003] At present, the main technical measures to improve th...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a welded extrusion crushing roller with a more firm combination of wear-resistant surfacing material and roller body in view of the shortcomings in the above-mentioned prior art. The crushing roller of the present invention can effectively solve the problem of Roller presses and other equipment are crushed and squeezed by insufficient wear resistance of the roll surface, and premature peeling off of wear-resistant surfacing materials leads to the failure of the squeeze roll, improving the life of the squeeze roll, which can effectively ensure the long-term safe and reliable operation of the roll body, and has The advantages of higher crushing efficiency, more uniform material crushing, wear-resistant surface and not easy to drop blocks can significantly improve the production efficiency of the roller press
