Aluminum oxide ceramic ball with high wear resistance and preparation method thereof

Abstract

The invention discloses an aluminum oxide ceramic ball with high wear resistance. The aluminum oxide ceramic ball is prepared from, by weight, 100 parts of high bauxite, 5-12 parts of titanium carbonitride, 0.2-0.8 part of chromium powder, 5-15 parts of electro-fused zirconia powder, 1-5 parts of wollastonite, 2-10 parts of activated clay, 3-12 parts of kaolin, 0.5-1.5 parts of calcium carbonate, 0.2-1.5 parts of lithium carbonate, 0.1-0.5 part of lanthanum oxide, 0.1-0.5 part of yttrium oxide, 0.1-0.5 part of europium oxide, 0.2-1 part of tetraterbium heptaoxide, 0.3-0.8 part of holmium oxide and 0.1-0.5 part of copper oxide. According to the aluminum oxide ceramic ball with the high wear resistance and a preparation method thereof. The preparation method is simple in process and mild in condition, and the obtained aluminum oxide ceramic ball is excellent in anti-impact property and good in wear resistance and can meet the use requirements of a cement grinding system.

Description

technical field [0001] The invention relates to the technical field of wear-resistant balls, in particular to a high wear-resistant alumina ceramic ball and a preparation method thereof. Background technique [0002] In recent years, relevant state departments have been advocating "energy saving and consumption reduction", striving to reduce the operating costs of enterprises and reduce the waste of resources by various production enterprises. As an important part of my country's economic development, cement enterprises have gradually entered the ranks of "energy saving and consumption reduction". In the cement production process, the energy consumption in the "two grinding" process accounts for the vast majority of the entire cement production process. Therefore, under the relevant national policies of "energy saving and consumption reduction", how to improve grinding efficiency and reduce grinding electricity Reducing consumption and improving the output of ball mills have...

Problems solved by technology

Alumina ceramic balls are considered to be the best choice to replace steel balls due to their suitable hardness, moderate density, wear resistance, corrosion resistance, and low price. Aluminum ceramic balls are still not well understood. The impact resistance and wear resistance of existing alumina ceramic balls are not very ideal. In the process of use, there are defects of high breakage rate and poor stability.
