Grinding- Bauxite Ball Mill/Raymond Roller Mill Because the bauxite is of 2.5-3.5 Mohs hardness, ball mill or Raymond roller mill are alternative for the raw ore treatment. If the bauxite ore size is too large, a jaw crusher can be used to break the raw material before grinding to meet the feed requirements of the ball mill or Raymond mill.
Grinding Cylpebs For Ball Mill. Grinding cylpebs is a type of grinding media with a short cylindrical or truncated conical shape.
