The alumina balls made by Hito Technical Industries, HITO 92HD, are balls with a minimum of 92% of alumina content, and the balls with the highest density of the market. HITO 92HD balls are characteristics due to their high resistance against wear rates, basically to the strict selections of alumina sintering doping agents, which allow a perfect control at the firing temperature process and then to reach the proper crystalline structure.

Mentioned low wear rates together with the high mechanic properties of HITO 92HD balls let to the end-users to reduce milling times, increasing efficiency during the process, getting, as well, and great economical save in comparison with other grinding media.

HITO 92HD balls are widely used for grinding raw materials at different sectors: ceramics, mining, cements……
