Ball Mill Design/Power Calculation. 2019-4-27 · 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 of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns).
(coefficient of reduction), the work index of the material, the mill shaft power and the specific gravity of the material. These parameters are thoroughly studied in [4, 5] and an empirical relation is suggested expressing the mill capacity as a ratio of the mill shaft power and the energy consumed in the grinding .
Recommended for product research, quality control of raw materials and assisting with technical service applications. Laboratory Mini Mills use grinding media to develop the high shear and impact forces required to reduce agglomerates or finite particles. Capable of producing sub-micron particles using limited amounts of raw materials.
Grinding Media Grinding media are the means used to crush or grind material in a mill. It comes in different forms such as alumina oxide balls, ceramic cylinders, or soda lime glass. At Norstone Inc., we offer all types of medias used for grinding, deagglomeration, polishing, deburring, fillers, proppants, spacers, refractory beds and shot peening.

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 tear.
Even faster speed will result in the media centrifuging inside the mill and virtually no milling or movement of media or product will occur. In most cases, the ideal mill speed will have the media tumbling from the top of the pile (the shoulder) to the bottom (the toe) with many impacts along the way.
