wet ball mill for metal ores and non-ferrous metals wet

In the process of grinding, due to the different grinding materials, a proper amount of water or anhydrous ethanol will be added to the wet grinding ball mill. Steel ball and liquid participate in the grinding process together. The common ratio of steel ball, material and water in the wet grinding mill is 4:2:1. Depending on the nature of the grinding material, the actual ratio will be adjusted, and the specific ratio needs to
