How to determine the formula to calculate depth 
It depends on how you are defining 'depth'. For example, if you have a rectangular box which is 2m wide and 3m long, you will need to know the volume to calculate the depth; Volume = length x width x depth Therefore; Depth = Volume / (length x w

Optimization of mill performance by using
Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. In today's global markets, expanding mining groups are trying

Measuring Countersink Diameter Using Gage Balls
I am still working through some examples of using gage balls for machine shop work. The following reference on Google Books has great information on using gage balls in measuring the characteristics of a countersink and I will be working through the presentations there. These are good, practical applications of highschool geometry.

How to Choose a Stepover  GRZ Software
In the images below we'll use a stepover equal to 1/10, 1/5, and 1/3 of the tool diameter to show this correlation. To put real numbers on this, that would be equavalent to a .012, .025, and .042" stepover for a .125" ball mill.

The larger the stepover, the larger the height of the scallops between passes will be. To hold this height below a certain limit, find the right stepover distance using the formula below. Here h is the height of these peaks—in inches, assuming the diameter is in inches—and D is the full diameter of the ball: ×
