Ball Mill Power Calculation Example#1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of80% passing ¼ inch(6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns).

SAG millproduct feeds two parallelball millsof 6.6 m×11.1 m (internal diameter×length), each with a 9.7 MW twin pinion drive. Theball millsare operated at a ball charge volume of …

The mill capacity of the best mix can be about 1.5 times higher than that of the worst mix. Interestingly, however, the optimum mix is a mix of two balls (50.8 mmand25.4mm) rather than a mix of three balls (50.8 mm, 35.9 mm and 25.4 mm) in all cases.

The latest design of theWiener ball millexhibits a highercapacitywhile using less energy and in combination with optimal cooling possibilities, product temperatures remain very low duringrefining.

The Work Index values listed in Table I and II apply directly to a wet grinding overflow type rod mill 7.5 feet in diameter in open circuit; and to a wet grinding overflow type ball mill 7.5 feet in diameter in closed circuit with a rake classifier at250% circulating load, and with80% or more of the feed passing 4 mesh.
