Jun 06, 2014 To make your ball mill work you must make the radius tangent to the side of the endmill, just like a ball mill is made. There are certain shapes that will not work with the solid sweep cut. A ball mill is an endmill with the corner radius being the same as the radius of the endmill.
Grinding in ball mills is an important technological process applied to reduce the balance equations relating to the mass components or the energy involved in the mixed model. In some cases the mills charge is considered to be perfectly mixed in.
We discuss the types of ball mill, the basic principles of the ball mill, how it works, the details of design including equations for optimum dimensions in all cases, some manufacturers for the ball mill, and estimation of the cost the ball mill. 6. 1. Introduction Ball mill is an efficient tool for grinding many materials into fine powder.
