Wear resistant alumina ball

Wear resistant alumina ball

Al₂O₃(%)≥70

Water absorption(%)≤0.02

Bulk densty(g/cm³)≥3.0

Features

  Excellent characteristics of high strength,high hardness,high abrasion resistance,high density,small size,high temperature resistance,corrosion resistance and no pollution.

  High purity,have no impact on the quality material by grinding;

  Bulk density can greatly improve grinding efficiency and reduce grinding time and effectively increase the effective volume of the ball mill to increase the quantity of abrasive material added.

  Low-wear can greatly extend the life of grinding mill;

  Characteristics of high temperature resistant, acid and alkali resistance and corrosion resistance.

Application
  •   Used in high speed stirred grinding mills;

      Ball mills as abrasive media for ceramic raw materials;

      Glaze materials in ceramic factories, cement factories, enamel factories;

      Used in 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,they will not pollute the grinded material as well;

      The mix and crush procedure of ceramics, glass, glaze and frits, chemical and plastic industries.
