Experimental Analysis of Semi-autogenous Grinding Mill
2019年10月4日 These mills with a giant cylindrical configuration with the diameter of 10–12 m are used for the grinding of ores. Semi-autogenous grinding of ore plays a vital role in a mineral processing plant. Since all ores have to be ground before any other process is carried on, any stop of the mill will shut down all downstream processes.
