Calculate and Select Ball Mill Ball Size for Optimum Grinding

02/08/2013  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

Grinding Rolling Elements in Bearings Norton Abrasives

23/11/2017  In each application, the grit size, the hardness grade and the structure of the grinding wheels are dependent on the ball size. For example, for small balls (4-9 mm) grit sizes between 200 and 280 (FEPA-F) are recommended, while grit sizes between 120 and 150 (FEBA-F) are better for big balls (60-80 mm). The below figure (1) demonstrates the Norton recommended specifications for different

Calculate Top Ball Size of Grinding Media - Equation

05/09/2015  These tests, called grindability tests, were needed to help determine the energy required to grind these materials from a coarse-sized feed to the desired product size. During the first half of the century, none of these test methods could be used to directly determine the energy needed for grinding at plant size capacity. If grinding tests for direct determination of the energy required were needed, pilot-plant tests in small-diameter continuous operating ball

Millstone - Wikipedia

These implements are often called grinding stones. They used either saddle stones or rotary querns turned by hand. Such devices were also used to grind pigments and metal ores prior to smelting. In India, grinding stones (Chakki) were used to grind grains and spices. These consist of a stationary stone cylinder upon which a smaller stone cylinder rotates. Smaller ones, for household use, were ...
