(4) Corrosion in wet grinding environment. In beneficiation plant, regulators in flotation operations are usually added during grinding operations, so that the pulp in the ball mill has a certain acidity and alkalinity, which usually accelerates the corrosion of wearing parts. (5) The material of the lining plate and the grinding ball do not match.
The water can wash away the fine particles in time to avoid over-grinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.
