The ball mill is a tumbling mill that uses steel balls as the grinding media the length of the cylindrical shell is usually 115 times the shell diameter figure 811 the feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 2040 water by weight

Effect Of Water Amp Density On Grinding Mill

Effect Of Water Amp Density On Grinding Mill

The time that the ore spends in the grinding mill is called retention time this is a very important variable the longer the retention time the more the ore comes in contact with the rods the better and finer the grind becomes to understand this important control it must be remembered that any volume that is added to a circuit must leave the circuit at exactly the same rate all the
