How To Distinguish Between Dry Grinding And Water Grinding ...

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.
