Bauxite Crushed Equipment

Use of Bauxite as an Abrasive. Calcined alumina is a synthetic corundum, which is a very hard material (9 on the Mohs Hardness Scale).Calcined alumina is crushed, separated by size, and used as an abrasive. Aluminum oxide sandpaper, polishing powders, and polishing suspensions are made from calcined alumina.
