Abstract

The invention belongs to the field of inorganic non-metallic materials, and particularly relates to a ceramic grinding ball and a preparation method thereof. The ceramic grinding ball is prepared fromthe components in parts by weight: 100 parts of garnet tailings modified materials, 17-20 parts of aluminium oxide, 0.6-0.8 part of yttrium oxide, 4.5-5.5 parts of zirconium oxide and 4-5 parts of kaolin. According to the ceramic grinding ball, self abrasion is low, at the same time, the preparation method is simple and feasible, and the production cost is low.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials, and in particular relates to a ceramic grinding ball and a preparation method thereof. Background technique [0002] Ultrafine grinding and purification is the basic process of deep processing of metal ore and non-metallic ore, and it is also a key process in ultrafine grinding of minerals, which requires the largest equipment investment, consumes a lot of energy and grinding media, and occupies a high production cost. Therefore, it must be obtained Mineral industry research departments and production companies are concerned, among which the choice of grinding media type directly affects the efficiency of grinding, determines the production cost of wet superfine and the physical and chemical performance indicators to ensure product quality. At present, the grinding media widely used in wet ultrafine grinding and purification equipment at home and abroad are ceramic grinding balls m...
