Effect of Water & 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
