  • Ball Mill Circulating Load Mineral Processing & Metallurgy

    29/04/2018· The circulating loads generated in a typical ball mill cyclone circuit contain a small fraction of bypassed fines. The concept that high circulating loads will result in overgrinding can be refuted by regarding increases in circulating load in the same vein as multistage grinding. That is, for every incremental increase in circulating load of 100%, an additional stage of grinding and classification occurs. With high circulating loads

    Very large tonnages can be ground with these ball mills because they are very effective material handling devices. 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).

    Add to this another 10%-15% above the ball charge for total of 23% to 25% product loading. So as a rule of thumb we use 25% solid loading. Empirical Check: Once the mill has been loaded and run for a few minutes, open the cover and look down into the mill. You should see some discernible layer of product on top of the media. If you can actually see the media then is too little solids charge. Most solids will

The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of

  • Ball mill Wikipedia

    A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It 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. The axis of the
