Comminution Wikipedia
Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes In geology, it occurs naturally during faulting in the upper part of the Earth's crust In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other2013年6月14日· Some ore, like that found in placer deposits, does not require crushing, as it is already in small pieces Most ore, however, is contained within hard rock that requires heavy duty crushing Mobile jaw crushing machine processing ore The goal of comminution is to crush the ore into small particles that contain only one mineral DryMineral Processing Part 1 | Geology for Investors
