The apparatus is a gyratory crusher in which all the wear parts can be removed and replaced from the top of the crusher, thus eliminating the need to remove large, heavy parts from below the crusher. This is accomplished by constructing the crusher so that the eccentric and the piston assembly can be lifted up and out sequentially. The piston assembly then includes all the wear parts within

A gyratory crusher uses a new head nut attachment apparatus. The gyratory crusher has a shell, a shaft disposed within the shell, a mantle covering a portion of the shaft, a head nut located above the mantle, and a sleeve between the head nut and the shaft. The sleeve is maintained in position on the shaft by means of a tapered contact surface between the sleeve and the shaft, and the head nut

The gyratory crusher can, just like a jaw crusher, accept boulder sizes close to 1.5 m (for the largest equipment). This crusher can handle products with a Mohs hardness that is not necessarily less than 5. As is the case for jaw crushers, there is not any mutual sliding on grinding surfaces, but simply rolling of the nut on concaves.
