Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
「Rod Mill Grinding Media To Feed Ratio」 Rod mills are very similar to ball mills, except they use long rods for grinding media. the rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. to prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
The grinding media may be the ore itself (autogenous grinding), bars, balls, or cylpebs, or even the ore itself together with a small amount of balls (semi-autogenous grinding). A survey found out that approximately 53% of the grinding circuits around the world use ball mills, and 38% use autogenous or semi-autogenous grinding, and therefore ...
8.1 Grinding 8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type.

ratio through a cascade loop. For example if the ratio is specified as 2, and Cyclone 2 particle size is 30 %+ 300 µm, the control loop will attempt to add water to Cyclone 1 sump to achieve a particle size of 15%+ 300 µm. If the hardness of the ore increases, the particle size in the mill discharge from ball mill 1 will increase. With the
