Abstract
A cone-type rock crusher includes a base, a fixed shaft projected upwardly from the base, a rotatable member positioned around the fixed shaft, a generally conical crusher head positioned over the rotatable member, and a stationary crushing surface over the head. The rotatable member revolves on a first set of bearings including a tapered roller thrust bearing between the top of the shaft and the rotatable member, a tapered roller radial bearing between the side of the shaft and the rotatable member, and a much larger tapered roller bearing between the side of the rotatable member and a carrier that is fixed in position with respect to the base. Both radial bearings have their tapered rollers arranged in a single row with the large diameter ends of those rollers presented downwardly to facilitate seating the rollers and to permit easy assembly and disassembly. The head is mounted on the rotatable member by a second set of bearings having its axis oblique to the axis of the first set so that as the rotatable member revolves, the head will wobble beneath the stationary crushing surface. The second set of bearings includes a large tapered roller bearing located between the side of the…
