Effect of Water Density on Grinding Mill 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

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 thees in contact with the rods, the better and finer the grindes. 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

This paper presents the experimental results on the effects of slurry Theology on ultra fine grinding by a stirred ball mill. The amount of dispersant, slurry density and the particle size were selected as the parameters. The viscosity of dolomite water slurry was measured by rotationaleters. It was found that by adding enough dispersant, the effect
Batch Mill Grinding of Ore Batch grinding affords the best opportunity for first studies of pulp consistency. Table 6 shows some of the results. The consistencies ranged from 80 to 20 percent solids.
