The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed. Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns.

Mill Speed - Critical Speed. Mill Speed . No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product.

The impact energy of grinding balls in horizontal tumbling ball mills with different drum diameters was analyzed using the discrete element method. The scale-up methodology for tumbling ball mills based on the impact energy was proposed.

Ball Speed is the speed of the golf ball immediately after impact. Ball speed is created by club speed and impact. Bad impact such as shots hit on the toe or heel will reduce the potential ball speed. “Glancing blows” created by hooks, slices, and hitting too much down on the ball can also reduce the potential ball speed.

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.

These equations are useful in calculating the speed (equivalent to velocity for present purposes) of a particle moving with constant acceleration at the moment it strikes an unyielding object, such as the ground or a solid wall. In other words, you can use them to calculate impact speed, or in terms of the above variables, v f.
