In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed ...
The capacity of the vertical raw mill is often the limiting factor for clinker output – when a plant upgrades the kiln system, the raw mill frequently becomes a bottleneck. Rather than investing in an entirely new vertical mill to keep pace, there is a very limited set of possibilities in upgrading existing mill capacity in smaller steps.
Keywords: Vertical roller mills, Corrosion, Abrasion resistant wear parts Introduction Vertical roller mills (VRMs) are comminution units primarily used in the cement industry for finish grinding of rocks (Fig. 1). For raw material VRMs, the media in contact with the wear parts is usually a mixture of limestone, clay and quartz sand.
