Critical rotation speed for ballmilling. ... The relation between the critical rotation speed of the jar and the ballcontaining fraction is depicted in Fig. 3. Read More. critical speed of of ball mill Critical speed in RPM is calculated by this relationship: Nc ... Ball 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. 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.
