Optimization of mill performance by using
Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. In today's global markets, expanding mining groups are trying
Effect of Pulp Density on Grinding
The consistencies ranged from 80 to 20 percent solids. The initial five tests will be considered first and the last one will be mentioned later. In the last test of the series of five (33 percent solids) so much water was used that the mill was filled. The thickest pulp required the most power; but it is unsafe to make so broad a generalization.
