Stripe type wear resistant grinding roller for vertical mill

Abstract

The invention discloses a stripe type wear resistant grinding roller for a vertical mill. The stripe type wear resistant grinding roller comprises a conical roller body, and multiple wear resistant stripes uniformly arranged on the outer surface of the conical roller body in the generatrix direction; temporary filling grooves are formed between every two adjacent wear resistant stripes; and material cushion layers are filled in all the temporary filling grooves, and are materials machined by the vertical mill. The stripe type wear resistant grinding roller for the vertical mill is surfaced with the wear resistant stripes with various shapes on the smooth surface, so that the friction force is increased, the materials are uniformly distributed between the grinding roller and a grinding disc under the effect of centrifugal force, the friction between the materials and the grinding disc is reduced, the grinding efficiency is improved, and the service life of the grinding roller is prolonged.

Description

technical field [0001] The invention relates to the technical field of wear-resistant grinding rollers, in particular to a striped wear-resistant grinding roller for vertical mills. Background technique [0002] At present, the crushing of materials in mines, cement building materials, thermal power, and thermal power industries is mainly carried out through the pressure of grinding rollers, which mainly involves the manufacture of wear-resistant materials for grinding rollers. The service life of grinding rollers and the wear speed of grinding rollers directly affect the crushing The operating efficiency, grinding efficiency and operating cost of the grinding machine, the current existing grinding rollers have short wear-resistant time, are easy to break and the wear-resistant layer falls off, so the service life of the crushing equipment is short and the work efficiency is low. [0003] The existing patent application number is 200920095684.2, which is called a wear-resist...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned patent application solves the durability, high efficiency and wear resistance of the wear-resistant roller, but it cannot solve the problem of the friction between the material and the grinding disc in the production process of the existing vertical mill, which easily leads to the wear of the grinding disc and grinding roller, especially It is a material with poor grindability and good fluidity for grinding, such as slag, nickel slag, etc.
