In order to study the relationship between grindability and particle shape, eight kinds of particle sizes and the seven kinds of shape indices of feed particles and unfractured particles were measured after impact crushing. The samples used were quartz and limestone. The size of particles ranged from 4 to 6 meshes.
As a result, the shape indices defined by (N/T), (L/T) and (F/T) are useful to characterize the grindability of particles.
