Ore crushing and grinding are the key technological processes of metallic mineral processing. In beneficiation production, the ore crushing and grinding equipment takes the largest proportion in investment, production costs, power consumption and steel consumption. Thus, to improve the processing property of the ore crushing and grinding equipment, develop large-scale and efficient ore crushing and grinding equipment and reduce the energy and steel consumption has become the development trend at present. In recent years, more and more novel ore crushing and grinding equipment has been developed, to obtain the bigger crushing ratio and finer ore size and reduce the grinding size and energy consumption. Moreover, with structure innovation and improvement through new technologies and materials, the ore crushing and grinding equipment now has better reliability and durability, improved performance and higher efficiency. Currently, the ore crushing and grinding equipment is developing towards the large scale, high efficiency, energy conservation and mechanical and electrical integration.
