Variables in Ball Mill Operation

Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art - it's just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables

Critical Speed Equation Ball Mills Waterberg2. Calculating critical speed of ball mills.The critical speed of the mill c is defined as the speed at which a single ball in equation 8 14 d is the diameter inside the mill liners and le is the rod and ball mills in mular al and bhappu r b editors mineral processing plant design chat now.

having a grate discharge. The ball mill, driven by a 1.5 hp motor, operated at a fixed speed of 53.8 rpm. This speed was 78.5 percent of the critical speed. The normal operating ball load was set at 230 pounds, and was comprised of 2.5, 2.0, 1.5, 1.0, and 0.75 in. diameter cast iron balls. The maximum size ball was determined by the equation

The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.
