### Simulation of Dry Ball Milling using Specific Power

The energy-size reduction relationship was the dominant form of mathematical model used in the description of tumbling mill grinding processes. Typically, in these models some single measure of product fineness (e.g. the 80% passing size, the size modules, the specific surface area) is chosen as the dependent variable and the energy input per unit mass of material being ground acts as the

Mathematical Simulation Of Dry Ball Milling Using Specific Power Information, The factor k = 1.35 was adequate to correct for the higher efficiency of vertical mills when compared to ball mills. In terms of net power, the vertical mill would be around 35% more efficient than the conventional ball mill.
