A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls,flint pebbles ...
Higher density grinding media generally results in faster grinding in a ball mill. An optimum grinding charge for a ball mill may be experimentally determined, however generally the range is from 20% to 50% of the mill volume, or to the center line. Approximately 30-40% of the ball charge will be void space.
Approximate ball loads can be estimated by assuming 300 lb. per cu. ft. of ball volume and a total load equivalent to 40 to 45 per cent of the mill volume. Rod loads average about 40 per cent of mill volume, and a figure of 400 …

The d thing is, they are the same ball, in the same box and the same weight, but one is a good 20% larger than the other. I can't tell if it's just that it has more air (which it definitely does) but they also feel different. I am hanging onto them only because they are what I need, but I know it will be irritating that they are different ...
If you feed 2 lb/hd, then the amount of CP supplemented is 2 lb/hd x 0.38 CP = 0.76 lb/hd CP. In another context, the NRC tables indicate that one month after calving a 1,200 lb cow with moderate milk production requires a diet that is about 10 percent CP. This same cow should have a DM intake of about 27 lb/day.

further reduced in size. Water is added to the ball mill, in which a slurry that usually contains from about 20 to 55 percent solids is produced (Singh, 2010; International Mining, 2011) (see fig. 2). The mill operates in a closed circuit with screens that size the ore and cyclones that sort the ore by size and density.
