sphere shape for mill grinding

Generating spherical surfaces Cutting Tool Engineering

Mar 01, 2013  The spherical surface generation technique can produce a full sphere. A single-point cutting tool sweeps through a circle that has no thickness on one side of the cutting edge. If you think about how a ring of any size smaller than the spherical surface can lay in full contact with the sphere, you can visualize how the cutting action takes place.

Jan 01, 2011  Models for understanding the basic concepts of fine grinding and how they apply to the design of stirred media mills have not yet matured. While spherical media in tower mills has previously been studied, real grinding media shape in stirred mills can range from spherical (steel/ceramic balls) to highly non-spherical (sand or slag) resulting in very different media and grinding dynamics.
