Rotational speed for ball mill. Critical rotation speed of dry ballmill was studied by experiments and by numerical simulation using Discrete Element Method DEM The results carried out by both methods showed good agreement It has been commonly accepted that the critical rotation speed is a function of a ball .
A grinding rate of a gibbsite powder sample was examined by using a planetary ball mill and it was well correlated with the specific impact energy, which was calculated by Discrete Element Method (DEM). This implies a fact showing the confidence of the simulation result. Based on this result, an optimum rotation-to-revolution speed ratio and […]

For ball milling, there is an optimum speed where the centrifugal force at the top of the mill is just balanced by the force of gravity. This caused the balls to be lifted to the maximum height before they fall onto the balls below, thus imparting the most kinetic energy. In practice, the ball mill is run at just below this speed (70–80%).

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.
Speed of rotation of the mill – At low speeds of rotation the balls simply roll over one another and little crushing action is obtained. At very high speeds, the balls are carried right around in contact with the sides of the mill and little grinding takes place. The minimum speed at which the balls are carried round in this manner is called critical speed of the mill.
