The crusher will be most effective when the mobile cone rotates around its axis. In that case, force Fro acts on the piece, creating an internal torque. Such behavior is feasible within a cone crusher with parallel axes of the crusher and the mobile cone, if the mobile cone is rigidly attached to its shaft.
