Steatite ceramic mill lining blocks are tough and hard to resist high impact, high abrasion and corrosion wear, high temperature resistant than steel, rubber, polyurethane, natural stone and other conventional mill lining materials. Under normal working conditions Steatite ceramic mill lining lasts many times longer than steel, rubber, stone and other conventional porcelain lining materials. Hardness of Steatite ceramic is 7.5 on Moh's scale and 500 at 10 kgs load on Vickers scale against the tool steel which is having hardness of 5.5 on Moh's scale, and 400 at 10 kgs load Vickers scale. Steatite ceramic is resistant to acids and alkalis except hydrofluoric acid. |
