Superfine grain size is reduced into the mill, to achieve more crushing less grinding most direct means

More crushing less grinding is home to beneficiation industry recognized an effective way of energy saving and superfine grain size is reduced into the mill, to achieve more crushing less grinding most direct means. Since the loop superfine mill product size can be broken down to 4mm. In this thesis, the theory and crushing equipment prototype test  electric meter  in-depth study, to improve the mill processing capacity, reduce over crushed, full use of resources and improve the economic efficiency of enterprises has important significance. Since the circulation of Kunming  air circuit breaker ultrafine mill is an efficient low developed patented new device. It uses the binder layer crushing, secondary crushing full use of the energy. Ore in the small roller outer wall and the inner wall of a large drum  electri cenergy meter  composed of automatic cycle, has been repeatedly broken. Device uses a clever forced discharging device, discharging material against water, mud affected. In the self-circulation superfine mill design and manufacturing based on a medium-pressure material layer crushing theoretical research, experimental research and broken particle size characteristics and regularity of power investigated crushing pressure, exhaust mine clearance, a small roller speed processing capability for self-circulation ultrafine grinding mill performance.
