size a mill. You must know the required annual capacity, whether batch or continuous operation will be required, which upstream and downstream processes will be needed for the mill, and the properties (such as size and shape) of the finished product. Fully characterizing the feed material is essential to identifying the right mill for the job.

Grit vs RA Chart. Ra (μin.) CLA (μin.) 1. A factor of 1.1 X CLA is used throughout this table to calculate RMS (μin.) 2. Typically, for values of Ra from 50μm to 3.2μm, the conversion factor for Rt (μm) is 4. As surface roughness decreases from 3.2μm, the conversion factor increases, reaching 12 at 0.025μm.

Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., dâ†"V = 0.40 K√F dB = ball size (cm) F = feed size (cm)
