the required size of a closed circuit ball mill for grinding manganese ore from a feed of mm to mesh at a capacity of tons h

The size of mill required for a specific grinding problem will depend on the character and size of the feed and the product desired and whether open- or closed-circuit grinding is desired. An accurate estimate of capacity can be made only by an engineer familiar with the proper evaluation of the factors involved
