Basic Comminution Concepts and Recent Trends in the Industry

Comminution in the mineral processing plant takes place in a sequence of crushing and grinding processes Crushing reduces the particle size of run of mine ore to such a level that grinding mill can further grind it until the mineral and gangue is substantially produced as separate particles Crushing is accomplished by nbsp
