Comminution - Grinding - Milling
Comminution means that material is crushed, grinded, milled into finer material. Comminution is energy intensive and hence often the most expensive segment of a mineral processing system.
Key is to minimize material volumes prior to comminution. That is achieved through pre-concentrating and gangue removal processes. Once that is achieved, the comminution must in perfect alignment with the subsequent processing mechanisms. That means that the comminution segment must result in a steady output of material of the desired size suited for further processing. Depending on the processing system material requires certain sizes of material. Fluctuations in comminution output affect all subsequent processing stages.
