ABSTRACT:
A gyratory crusher of the type including a frame with a bowl mounted on the frame and a head cooperable with the bowl in crushing operations. The head is rotatably mounted on an eccentric which is driven through suitable gearing. The head is positively rotated by a drive means either independent of or integral with the drive for the eccentric. The bowl is free to rotate about the frame. The rotary motion imparted to the head serves to induce centrifugal force to the particles of material within the crushing chamber. This centrifugal force, when combined with the gravitational force acting on the particles of material, results in the material moving through the crushing chamber in a trajectory which follows the configuration of the crushing chamber.
