Wet ball mill is a kind of equipment which uses grinding medium and a certain amount of liquid (water or anhydrous ethanol) to grind materials. Unlike dry ball mill, wet ball mill adopts the wet grinding method. The characteristic of wet grinding is that the material needs to be soaked in the liquid for grinding. This method can effectively reduce the chance of the material properties changing ...
