Ball Size vs. Grindability. It has been recognized that the grindability of an ore in a ball mill is a function of both feed and mill parameters: Work index, W i; Largest particle size and size distribution; Density of solids and slurry; Mill diameter; Rotational speed; Rowland and Kjos (1980) defined the largest ball size needed based on these
