Description

Technical Parameters

Product Ifo:

The high Alumina Grinding Ball has been widely used in high speed stirred grinding mills in mining applications. And ball mills as abrasive media for ceramic raw materials and glaze materials in ceramic factories, cement factories, enamel factories and glass work owing to the excellence of high density, high hardness, and high wear rate. during the abrasive/grinding processing, ceramic balls will not break up; it will not pollute the grinding material as well.

Size range of the isostatic pressed balls :Φ30-100mm
Size rang of the rolling formed balls:Φ1-30mm
