Abstract

The invention relates to a low-temperature sintered zirconium silicate grinding ball and a preparation method thereof, relating to a grinding medium. The raw materials of the ball are as follows: zirconium silicate as the substrate material; and a combination of alumina, silicon oxide, zirconia, yttrium oxide, calcium carbonate, magnesium carbonate, potassium carbonate and sodium carbonate as a sintering aid. The raw materials are prepared according to an appropriate mass ratio, and go through ball milling using a ball mill, and high speed grinding by a vertical sand mill then drying to obtain raw material powder for the preparation of the zirconium silicate grinding ball at low temperature. The material powder is shaped to be biscuit balls for sintering to obtain compact, wear-resistant and high-strength zirconium silicon substrate grinding balls.

Description

technical field [0001] The invention relates to a grinding medium-low-temperature sintered zirconium silicate grinding ball, and provides a preparation method of the grinding ball. Background technique [0002] Grinding balls are widely used in mining, metallurgy, chemical industry, food, building materials and other industries to pulverize and mix raw materials through various methods such as collision, friction, rolling and extrusion of grinding balls. The quality of grinding balls seriously affects production efficiency and product quality. [0003] In recent years, the rapid development of ultra-fine powder technology and the development and utilization of low-grade minerals have greatly promoted the development and production of grinding ball media. Commonly used grinding media are steel, quartz, glass, alumina, zirconia, etc. Zirconia has good specific gravity and is a high-end grinding material, but its price is relatively high, while the grinding efficiency of othe...
