# Forces Involved In Size Reduction In A Ball Mill The Q A Wiki

Nov 11, 2013 Ball milling is a common method in the size reduction of material. The milling process produces nanopowders through the impact forces generated by action of centrifugal forces. Milling parameters such as milling time, mass concentration, and bead amount are important parameters that need to be considered in producing superfine powders.

A force is a push or a pull that acts upon an object as a results of its interaction with another object. Forces result from interactions As discussed in Lesson 2, some forces result from contact interactions normal, frictional, tensional, and applied forces are examples of contact forces and other forces are the result of action-at-a-distance interactions gravitational, electrical, and ...
