Brief Introduction of Ball Mill

Ball mill is a horizontal grinding mill and key equipment for grinding materials, widely used in ore flotation processing plant and powder-making production line. According to different materials and discharging methods, there are dry ball mills and wet ball mills for choice. Dry ball mill is mainly for producing mineral powder used in cement, silicate product, new building material, refractory, fertilizer, black and non-ferrous metals and glass ceramic industry; Wet ball mill is a kind of continuous ball mill used in ore beneficiation plant. ...Learn More
