  • Comminution Wikipedia

    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 withIn this paper, the authors will review various methods for assessing comminution circuit efficiency in the context of the Newmont database, including the Bond, Morrell, and size specific energy (SSE) methodologies The authors will show that SSE method generates a relative efficient measure that allows equipment performance to be assessed in isolation and is in that sense comparable to theBENCHMARKING COMMINUTION CIRCUIT PERFORMANCE
