Various classifiers, such as screens, spiral

How To Choose a Stepover for 3D Profiling

To put real numbers on this, that would be equavalent to a .012, .025, and .042″ stepover for a .125″ ball mill. Stepover =1/10 of diameter. Stepover =1/5 of diameter. Stepover =1/3 of diameter. As you can see, the change in quality is so dramatic that you might be tempted to always use the smallest stepover possible.
