Recommended Ball Mill Speed & Liner Configuration
Nc = 42.3/√D (meters) or Nc = 76.63/√D (feet) In practical terms, one must assume some mill diameter, usually about 150 mm (6 inches) less than the mill inside shell or nominal diameter, that allows for the difference between the mill inside diameter and the location of the centre of gravity of the ball, as well as an assumed liner ...
Grinding Media Wear Rate Calculation in Ball Mill
Then in ball-wear formula (25), T = 6.9/K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = 6.9Wt/Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/6.9Wt are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.

Embedment Length of Steel Liner in Different Types of Soil
The results indicate that the embedment depth increases from 10 to 20D with reduction in N values from 40 to 2 for clay soil, 11D–23D for the N values of 70–4 in sandy soil and in rock strata 3.6D–7D for the N values of 600–80. The above procedure does not consider the unsupported length of steel liner.
