## Wet Ball Mill for Metal Ores and Nonferrous Metals Wet

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· Optimum Ball Mill Speed Mill speed is generally referred to as a percentage of critical, which is defined as the speed at which an infinitely small particle just follows a smooth shell lining in its motion An increase in the mill speed will give a directly proportional increase in mill power but there seems to be a square proportional increase in the wear Rod millsBall Mills Mineral Processing & Metallurgy
