Wi = The Bond Ball Mill Work index is a measure of the resistance of the material to crushing and grinding . A Bond Ball Mill Work Index test may be required for the design of a new mineral processing plant . It is determined by Bond Ball Mill Grindability test in a lab using a Bond Mill.
This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.

Rod mill, Ball mill and SAG mill as examples are combining in comminutioning process based on particle size and hardness after crushing. Rod mills are suitable for preparation of feed to gravity concentrators, certain flotation processes, magnetic cobbing and ball mills. Actual diameters in use for rods range from 25 to 150mm.
Trommels remain widely and often work with the screening of mill discharge streams. Tumbling mill discharge streams usually pass through a trommel screen attached to the mill outlet to prevent grinding media scats from reaching subsequent processing equipment, and the case of AG/SAG mills, to extract pebbles to ...
