Abstract :
The computer-based control and the implementation of an energy-efficient pressure cycle comminution technique for ore reduction are presented. The effects of various parameters, such as permeability, porosity, saturation time, and applied pressure, on process performance and modeling of a machine designed to reduce the particle size of porous material in tension through the use of rapid depressurization of water-saturated ore are discussed. In addition, the synergistic effect of surface energy modifiers and pressurization to achieve better performance is discussed
