Ball Rod Mill DensityHow Water Impacts Grinding

 · Density if you recall is the ratio of ore to water and is measured as a percent of solids in the water. It will control the grind in two ways. It affects retention time and helps distribute the ore through-the mill so each piece of rock will come in contact with the surface of the rods. To maintain a proper balance between these two is critical.

 · The Bond s equation for ball sizing (McIvor 1997) can help in selecting the ball size for a given ore and grinding mill. Ball mill simulations with ball wear modelling can also be used to identify the optimum ball size (Concha et al. 1992) for a given application. However the usual practice is to conduct full scale trials during which the actual ball charge is slowly modified by the addition of new balls as replacement of the worn media evacuated from the mill.
