Other sizes can be produced by customer's special request..

Smelting Furnace:We have brown corundum dumping furnace and fixed furnace,can reach different customer special requirement. the dumping furnace have very small crystal than fixed furnace,so the products have the high toughness and good anti-impact ability,It is well used in vitrified application and can improve the grinding efficiency.

Bulk Density:We have barmac,ball mill,roll mill production line,can crushed different bulk density as customer's special requirement
