For this coarser feed the 50 2010 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower.
A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21. The largest SAG mill is 4239 12.8m in diameter, powered by a 28 MW 38,000 HP motor. A SAG mill with a 4439 13.4m diameter and a power of 35 MW 47,000 HP has been designed.
typical ball size of ball mill . Ball mill. The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc as well as for ore dressing of both ferrous and nonferrous metals The ball mill can grind various ores and other materials either wet or dry
Fig. 8 shows the optimum composition of the makeup ball sizes for various feed sizes as a function of the size reduction ratio, R. Because mixtures of two balls 50.8 mm and 25.4 mm ball are always found to be optimum, the results are plotted with the ordinate being the fraction of 50.8 mm balls.

The point where the mill becomes a centrifuge is called the 34Critical Speed34, and ball mills usually operate at 65 to 75 of the critical speed. Ball Mills are generally used to grind material 14 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed
The large gun values were 4, 6, 9, 12, 18, 24, 32 and 42 pounds lb , where 1 lb 0.45 kg. The values were based of the various cannonball sizes in use, but some simple calculations shed light as to why these particular weights of cannonball came to be chosen. Round shot diameter vs mass. Working in Imperial units of inches in and pounds

BallRod Mills, based on 4 liners and capacity varying as 2.6 power of mill diameter, on the 5 size give 20 per cent increased capacity on the 4 size, 25 per cent and on the 3 size, 28 per cent. This fact should be carefully kept in mind when determining the capacity of a Steel Head BallRod Mill, as this unit can carry a greater
Mill ball sizes and combinations should be determined according to size of feed materials and targeted particle sizes 53. For example, larger particles crack faster by grinding with larger mill
Ball mill Wikipedia. A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sinteringIt works on the principle of impact and attrition size reduction is done by impact as the balls drop from near the top of the shell A ball mill consists of a hollow cylindrical shell rotating about its axis T
