what is the critical speed of ball mill. 2.2 Rotation Speed Calculation of Ball Mill Critical Speed_ When the ball mill cylinder is rotated there is no relative slip between the grinding medium and the cylinder wall and it just starts to run in a state of rotation with the cylinder of the mill.

Get Price##### Speed of rotation of the mill At low speeds of rotation

Speed of rotation of the millAt 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.

The rotation is usually between 4 to 20 revolutions per minute depending upon the diameter of the mill. The larger the diameter the slower the rotation. If the peripheral speed of the mill is too great it begins to act like a centrifuge and the balls do not fall back but stay on the perimeter of the mill.
