Steatite
ceramic mill lining bricks 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.
