In the present study, the effect of the rate of the input of comparable amounts of energy into the material being processed on the particle size and on the value of specific surface area of the particles was analysed. It was shown that, irrespective of the rate of the energy input into the material, the resultant particles have similar characteristics, including their size and shape, and the value of the specific surface area. A more intense action exerted by the grinding bodies on the particles in the material being processed is accompanied by a sharp increase of temperature throughout the entire system. The heated particles plasticize, thus undergoing to a rolling-type granulation process.
