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

Critical speed is defined as the point at which the centrifugal force applied to the grinding mill charge is equal to the force of gravity. at critical speed, the grinding mill charge clings to the mill inner surface and does not tumble. most ball mills operate at approximately 75% critical speed, as this is determined to be the optimum speed
