High alumina grinding ball

The wear-resistant alumina ball is made of selected high-quality raw materials, advanced molding technology, and calcined in a high-temperature tunnel kiln. 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 processing glazes, blanks and various mineral powders. Products are widely used in ceramics, cement, coatings, refractory materials, inorganic mineral powders and other industries.

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

Rolling ball: wear-resistant alumina ball formed by rolling.

Brim: The forming marks formed on the surface of the wear-resistant alumina ball during cold isostatic pressing.

Radial size: the maximum diameter of the ball measured parallel to the direction of the ball cap.

Weft dimension: the maximum diameter of the ball measured perpendicular to the direction of the ball cap.

Sphericity: the ratio of the difference between the radial dimension and the latitude dimension of the pressed ball to the standard dimension.

Abrasion: The weight loss of the wear-resistant alumina ball after being ground in a polyurethane tank with water for a certain period of time.
