Ball Mill Application and Design. Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of 188 to 15 The particles to be milled are trapped between the grinding media or balls and are reduced in size …

Ball & Rod Mill Density – How Water Impacts Grinding. Density, if you recall is the ratio of ore to water and is measured as a percent of solids in the water. It will control the grind in two ways. It affects retention time and helps distribute the ore through-the mill so each piece of rock will come in contact with the surface of the rods.

Grinding balls for mining are generally used to break down secondary materials such as rock, cement and stone during the extraction of ores and metals. AISI steel grinding balls for ball mill applications typically have a tolerance of ±0.05/±0.10 and a density of 7.70 to 7.95. Exceptions include Al series 1XXX and Al 6061 which have the same ...

As you increase the volume of the through put, the time that the ore has to react to the grinding media is lessened. As you add ore to the mill you are also adding WATER and changing density which affects the slurry rheology and workings of the grinding action inside that mill. This water is one- of the main controls that you have over your grind.
