crushing rock form

Cone Crushers | McLanahan

The bearing force as it is transmitted to the main shaft provides the required moment to crush the rock. The distance between the bearing force and the fulcrum point is called the force arm. The longer the force arm, the greater the momentum, which produces a greater crushing force. Crushing loads are distributed over a large spherical bearing.
