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 minimum-size cement plant in 1971 appears to have produced about 1,000,000 bbl/year, with 16 percent being over 5,000,000. A 3 million bbl plant could take the output from a 1000 MWe power plant. Electrical requirements would be 76,000 MWh/yr, or about 230 MW, based on a 330-day operating year.

Portland cement rock is sold directly by the gypsum producer to a cement plant, usually under some type of long-term contract.
