Stresses generated in the ball charge increase which may result in spalling of balls and blocking the grate discharge. 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.
Results show that with the six parameters abovementioned estimated the charge mixture is fully characterized with about 5 10 deviation. Finally the estimated parameters can be used with confidence in the simulator model allowing one to find the optimal ball charge distribution for a set of operational constraints.
To predict ball mill grinding behavior using the dis-crete element method we must first be able to repro-duce the balls motion in the ball mill using simula-tions. Kano et al.8 have made it clear that it is possible to reproduce the ball motion when the solid material is also present in a tumbling ball mill without fins by pro-

Some experimentation is inevitable in determining the exact amounts of material charge to use. While the media charge should always be 50 material charge will vary from 25 to 40 or more in some cases such as when grinding 100 homemade airfloat charcoal. The best way to tell if your mill is properly charge is to listen to it after
