This invention discloses a rock, stone or other solid material crushing device. It consists of a crushing chamber, a rotator shaft running through the chamber, an outer cutting blade secured to the chamber, a set of outer cutting bars which are secured to a disk which is secured to and rotates with the rotator shaft and acts as a mechanism for breaking apart the solid material to be crushed. Within the rotational arc of the outer cutting bars is a pair of inner cutting blades. Inside of the inner cutting blades and attached to the rotator shaft disk is a second set of cutting bars, i.e. the inner cutting bars. The inner cutting blades are secured to the outside of the crushing chamber and intrude into the crushing chamber such that the outer cutting bars rotate outside of the pair of inner cutting blades and the inner cutting bars rotate inside the inner cutting blades. This crushing device provides three locations for the breaking apart of the solid material, a vast improvement over prior art devices which only provided one crushing or breaking mechanism within each crushing chamber.
