The acceleration factor of the ball or rod mass is a function of the peripheral speed of the mill. Thus. n = c9np/√D, the above equation becomes P = f1 (D²)·f5 (πD c9 np/√D) = cs np D2.5. As a first approximation, the capacity, T, of a mill may be considered as a function of the force acting inside the mill.
