Cement Kilns: Size Reduction and Grinding

A particle of negligible size and mass m just remains in contact with the mill lining at the "12 o'clock" position if the centrifugal effect (mv 2 /r) is equal to the gravitational force (mg), where v is the peripheral velocity in m/s and r is the radius inside the lining in metres. The circumference of the mill is 2πr metres so v = 2πrN/60

Effects of Particle Size Distribution on the Burn Ability

Equations 4 and 6 were respectively called Rittinger and Kick’s laws. Supposes that the energy required is directly related to the reduction ratio L 1 /L 2 which means that the energy required crushing a given amount of material from a 50 mm to a 25 mm size is the same as that required reducing the size from 12 mm to 6 mm. In equations above, KR and KK are known respectively as Rittinger’s
