The wear-resistant alumina ball is made from high-quality tunnel kiln by using high-quality raw materials and advanced molding technology. The product has the characteristics of high density, high hardness, low abrasion, good seismic stability and corrosion resistance. It is the most ideal grinding medium for glaze, billet and various mineral powder processing. Products are widely used in ceramics, cement, coatings, refractory materials, inorganic mineral powder and other industries.

Pressed ball: wear-resistant alumina ball formed by cold isostatic pressing

Rolling ball: wear-resistant alumina ball formed by rolling

Brim: A molded mark formed on the surface of a sphere by a wear-resistant alumina ball during cold isostatic pressing.

Radial dimension: The maximum diameter of the ball measured by pressing the ball parallel to the direction of the ball cap.

Zonal dimension: The maximum diameter of the ball measured by pressing the ball perpendicular to the direction of the ball cap.

Sphericality: The ratio of the difference between the radial dimension and the weft dimension of the pressed sphere to the gauge size.

Abrasion: The weight loss of the ball after wear-resistant alumina balls in a polyurethane tank for a certain period of time [2].

Alumina grinding balls refer to industrial alumina powder, high-temperature calcined alpha alumina powder and other materials as raw materials, which are produced through processes such as batching, grinding, milling (pulping, mud-making), molding, drying and baking. A ball which is widely used as a grinding medium.

According to different alumina content, it can be divided into medium aluminum ball, medium high aluminum ball and high aluminum ball.

Generally, we classify 60%-65% alumina content as medium aluminum ball, 75%-80% alumina content as medium-high aluminum ball, and 90% or more alumina content as high-aluminum ball. Among them, the high aluminum ball is subdivided into 90 porcelain, 92 porcelain and 95 porcelain.

The medium aluminum ball and the medium high aluminum ball are accepted by most ceramic factories because of their low price, and are mainly used for grinding ceramic blanks. Due to its high strength, high hardness and high wear resistance, high-aluminum balls are widely used in different types of ceramics, enamels, glass and chemicals due to their superior characteristics, small volume, high temperature resistance, corrosion resistance and pollution-free properties. Such as the factory's thick and hard material finishing and deep processing, especially the 92-content high aluminum ball is most commonly used.

The abrasive-type ceramic ball is an abrasive body used for a fine pulverizing apparatus such as a ball mill, a pot mill, or a vibration mill. Grinding ceramic balls have the advantages of high hardness, large bulk density, corrosion resistance, etc. Their pulverization efficiency and wear resistance are much better than ordinary ball stones or natural pebbles, and are widely used in ceramics, glass, enamel, pigments, chemicals and other industries.
