Which is better to use zirconium ball, steel ball, alumina grinding ball in ball mill

At present, ceramic balls and alumina balls are mainly used for grinding in the market because of its low price. At least use zirconium balls, steel balls, and alumina grinding balls. This should be considered based on the properties of the materials, electricity costs, and grinding efficiency.

Zirconium ball density 6.0g/cm³

The density of steel balls is 7.85g/cm³

The density of alumina grinding ball is 3.6g/cm³

Generally, we classify 60%-65% alumina content as medium aluminum balls, 75%-80% alumina content as medium-high aluminum balls, and over 90% alumina content as high-aluminum balls. Among them, the high-alumina balls are subdivided into 90 porcelain, 92 porcelain, 95 porcelain and 99 porcelain. Due to its extremely high production cost, few large-scale manufacturers produce 99 porcelain in large quantities. At present, it is mainly made by hand by some special ceramic factories.

Medium alumina balls and medium-high alumina balls are accepted by most ceramic factories due to their lower prices, and are mainly used for grinding ceramic blanks. High-alumina balls are widely used in different types of ceramics, enamels, glass, and chemicals due to their excellent characteristics such as high strength, high hardness, high wear resistance, high specific gravity, small size, high temperature resistance, corrosion resistance, and non-polluting. For the finishing and deep processing of thick and hard materials in factories, among them, high-aluminum balls with 92 content are the most commonly used.

Wear

In terms of wear alone, steel balls wear the most, followed by alumina grinding balls, and zirconia balls the least.

Toughness

Zirconia balls and steel balls have better toughness, while alumina grinding balls are worse.

Requirements for grinding materials

steel balls are not resistant to acids and alkalis, alumina balls and zirconia balls are resistant to acids and alkalis, and have a wide range of applications.

Impact on grinding materials

depending on the specific material requirements, some requirements cannot contain iron, then steel balls cannot be used, only alumina balls and zirconia balls can be used.

Price

The prices of steel balls and alumina grinding balls are similar. Zirconia balls are more expensive. However, because of their excellent characteristics, zirconia balls are widely used as grinding media in sand mills, high-speed mixing mills and other machines, and have a higher cost performance

Abstract: High alumina ball is a good neutral material, we can use it as a wear-resistant abrasive material for correct use. High alumina balls can be subdivided into 90, 92, 95, 99 series according to alumina content. The common grinding media on the market are pebbles, alumina balls, steel balls, glass balls, zirconia balls, silicon
