Mill Capacity for Dry Grinding. To obtain dry grinding Work Index from Wet Grinding Index multiply W iWET by 1.3. In this case, therefore, the work index for dry grinding = 13.7 1.3 = 17.8 kWh/t. Substituting this value for W i into Equation (7.46) Q (dry grinding) = 25.3 t/h

How To Distinguish Between Dry Grinding And Water

How To Distinguish Between Dry Grinding And Water

The reason is that the stone has absorbed water and the ground is wet during the water grinding in the low-grade section, so it can be dry ground after 1000 mesh. Moreover, through the heat of dry grinding, it can accelerate the evaporation of water and dry the stone ahead of time, saving waiting time for the crystal glaze sealing operation
