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 ...

The grindability test (ASTM D409, ISO 5074) uses a ball-and-ring type of mill in which a sample of closely sized coal is ground for a specified number (usually, 60) of revolutions. Then the ground product is sieved and the grindability index is calculated from the amount of undersize produced using a calibration chart.

• Ball surface wear rate is approximately constant, but with variations due to hardness, and other factors. Consumption is closely related to total ball charge surface area. • A useful guideline for make-up ball size for a new circuit was provided by Bond (1958). B = (F80/K)0.5 x [(WI x SG)/(Cs x D0.5)]1/3 (3) In the historical British units:
