Problems solved by technology

[0002] Grinding body is an indispensable and commonly used consumable material in powder preparation, ceramics and refractory industrial production. Synthesizing materials with strong adaptability, high hardness and toughness is a very valuable research direction in the field of grinding materials. During use, sand, hard fibrous substances and other media with hard, rough surface, cutting properties, high temperature, impact, corrosion, etc. will cause serious wear and tear losses, leading to premature scrapping or failure, affecting the quality of the equipment. Normal operation and production progress, the requirements for corrosion resistance, hardness, toughness and wear resistance of grinding bodies are getting higher and higher

Abstract

The invention discloses a grinding body for a corrosion-resistant high-hardness high-toughness ball mill. The grinding body is characterized by comprising the following raw materials in parts by weight: 20-30 parts of carbon tungsten alloy, 20-25 parts of silicon carbide grains, 20-30 parts of modified aluminum oxide, 5-10 parts of rare earth ferro-silicon alloy, 5-8 parts of epoxy modified phenolic resin, 10-15 parts of silica, 10-15 parts of perovskite, 5-8 parts of ferro-molybdenum powder, 4-5 parts of zircon, 10-15 parts of barium sulfate, 2-4 parts of iron-based powder, 2-4 parts of silica powder and 2-4 parts of quartz sand. The grinding body for the corrosion-resistant high-hardness high-toughness ball mill is high in wear resistance, extremely high in hardness and high in toughness.

Description

technical field [0001] The invention relates to the technical field of grinding bodies, in particular to a corrosion-resistant, high-hardness and high-toughness grinding body for ball mills. Background technique [0002] Grinding body is an indispensable and commonly used consumable material in powder preparation, ceramics and refractory industrial production. Synthesizing materials with strong adaptability, high hardness and toughness is a very valuable research direction in the field of grinding materials. During use, sand, hard fibrous substances and other media with hard, rough surface, cutting properties, high temperature, impact, corrosion, etc. will cause serious wear and tear losses, leading to premature scrapping or failure, affecting the quality of the equipment. In normal operation and production progress, the requirements for corrosion resistance, hardness, toughness and wear resistance of grinding bodies are getting higher and higher.
