In a two-chamber mill, the media in the second chamber are typically in the range 15–40 mm, although media down to 5 mm are sometimes encountered.Calculate and Select Ball Mill Ball Size for Optimum Grinding 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 .Cement grinding Vertical roller mills versus ball mills By these measures it has been possible to obtain particle size distributions for cement ground in OK mills similar to those for cement ground in ball mills (BM), as shown in Figure 6. Figure 6: B It should be noted, however, that operation to achieve a wide particle size distribution (low n-value) has a cost.

Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications). View chapter Purchase book Manufacture of Portland CementGrinding Mills - 911Metallurgist In the manufacture of standard cement by grinding cement clinker, the clinker is reduced from 1″ or finer down to a specific surface of 1750 sq cm per gram. This area can be produced by an open or closed circuit grind.Effect of ball and feed particle size distribution on the . Fig. 8 shows that the small 10 mm ball size is superior in generating more material in the fines size class, from both feed sizes used. If an objective function was to maximize the production of fines e.g. in the cement industry, the A.R shows that use of smaller ball sizes would give superior results.
