A mill is a machine that is used to break down solid materials into smaller pieces by cutting, grinding, or crushing. The process of milling includes the use of force that acts on a material to tear it apart and reduce its size. Milling improves the performance of ingredients, and the products made from them.

Grinding, with its mm precision in dimensions, is typically used as a finishing operation that removes only a small amount of metal (between and mm). While grinding can quickly remove large volumes of metal in some roughing applications, this is not the case in most cases. Thus, grinding is a wideranging profession.

Vibratory mill does not rely on rotation for the main grinding action. The vibrating mill has a grinding chamber which is filled to around 65 % to 80 % of its capacity with grinding media such as balls or rods. The chamber is vibrated at a frequency of between 1000 and 1500 times per minute (can be variable speed) by cams or unbalanced weights.
