Fig. 2 b shows a large gyratory crusher processing run of mine ore to 100150 mm followed by two stages of cone crushing to generate a P80 of 612 mm which could be fed into a large ball mill operating in closed circuit with hydrocyclones. By using multiple process lines, these circuits could process up to 100,000 tonnes of ore per day.

Description Pulverization is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion.
