Investigation of the comminution process in pendular ...
Each grinding body, usually referred to as grinding roller, is part of a pendulum which is attached to the cross head. By rotating the cross head a centrifugal force is applied to the pendulums, forcing them against the grinding ring. It is in the gap between the grinding ring and the grinding roller where the comminution process takes place.

Centripetal Force - Pendulum Form
A pendulum bob has two primary forces acting on it. One is the constant downward force of gravity, mg. The second is tension in the string which changes in both size and direction as the pendulum swings. When it swings through the bottom of its arc, the pendulum has maximum speed and requires the maximum force to hold it in its circular path.

Centripetal Force - Pendulum Form
A swinging pendulum follows a path that is circular in shape. In order to maintain this path, an unbalanced force towards the center of the path, a centripetal force, must be acting. The size of this net force is mv 2 /R, where m is the mass of the pendulum bob (assuming a massless string), v is the speed or velocity and R is the radius.
