The work index in bonds law for crushing of solids has the following dimensions a no units dimensionless b kwhton c kwton d kwhm 12 ton
Abstract the bond work index is a measure of ore resistance to crushing and grinding and is determined using the bond grindability test its value constitutes ore characteristic and is used for industrial comminution plants designing determining the bond work index
Meaning is expressed include the rittinger number crushing resistance hardgrove index and bond work index the bond work index is regarded as one of the crushing resistance it can therefore be presumed that the bond work index is correlated to the mechanical properties of materials 4
