Chapter 3 - Particle Technology (Size Reduction) Kick's law: the work required for crushing a given mass of material is constant for the same reduction ratio, ... 3.2.2 Bond crushing law and work index.
The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.
The work index is the comminution parameter which expresses the resistance of the material to crushing and grinding. Numerically the work index is the kWh per short ton required to reduce the material from theoretically infinite feed size to 80 per cent passing 100 microns, equivalent to about 67 per cent passing 200 mesh.
