Factors to be considered are:

Feb 08, 2017 Mill productivity also depends on other factors: number of the drum rotations, the grinding fineness, humidity and size of the crushed material, timely removal the finished product. Ball mills characterized by high energy consumption. When the mill idles, the energy consumption is approximately equal to the energy consumption with full mill

Jun 06, 2016 AG/SAG mills as a primary grinding stage in a circuit with or without additional stages of comminution ... ball mill tests but pilot plant tests on 50-100 tons of ore are frequently necessary for autogenous or semiautogenous mills. Preparation and selection of the test sample is of utmost importance. ... Semi Autogenous Design Factors. The

Selection of Grinding Wheels for Thread Grinding and Tool Sharpening: The factors influencing the type of abrasive for thread grinding wheels are the material of workpiece, its hardness, pitch and profile of the threads. Al 2 O 3 wheel is preferred for most of the applications. For grinding titanium, SiC wheel is used and for grinding carbide
