Vibratory ball mills use high-frequency vibration to make grinding media in the cylinder produce inertial impact force. Raw materials are ground under the impact. The grinding media is usually φ16~φ36mm steel ball or steel rod. After carburizing and quenching, their hardness can reach above HRC55.

Raw mills usually operate at 72-74% critical speed and cement mills at 74-76%. 3.2 Calculation of the Critical Mill Speed: G: weight of a grinding ball in kg. w: Angular velocity of the mill tube in radial/second. w = 2*3.14*(n/60) Di: inside mill diameter in meter (effective mill diameter). n: Revolution per minute in rpm.

R- the radius of the ball. The volume of a grinding ball is determined by the formula: V=4/3*π*R 3, where: V- the volume of the ball. π – PI constant, a mathematical constant that is equal to the ratio of the circle's circumference to its diameter. 3.14 is a commonly used value for PI; R- …
