Basic Comminution Concepts and Recent Trends in the Industry

Comminution is the process in which the particle size of the ore is progressively reduced until the clean particles of mineral can be separated by such methods as are available. Comminution in its earliest stages can also be carried out in order to make the freshly excavated material easier to handle by scrapers, conveyors,

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,

Energy recovery potential in comminution processes c

Comminution processes are cited as having an efficiency of less than 1%. Even if the efficiency of these processes could be increased to 5% as is suggested to be possible, the conclusion would remain that com minution processes are very inefficient with some 95% of the input energy lost to the environment as heat.

Energy and population balances in comminution process modelling

Sep 6, 2006 The results of theoretical and experimental studies of a comminution process are presented. There are two random functions: the selection function and the breakage function in the stochastic model based on a population balance. This model enables prediction of particle size distributions of comminution
