SIZE EFFECT ON SPECIFIC ENERGY DISTRIBUTION IN PARTICLE

04-04-2017The energy consumption for comminuting single particle is found to be proportional to the 5(D−3)/3rd order of the particle size, D being the fractal dimension of particle comminution daughter. The Weibull statistics is applied to describe the relationship between the breakage probability and specific energy of particle comminution.

Comminution

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with
