ABSTRACT:
A conical crusher having a power draw of approximately 1,000 Hp and capable of being installed in a conventional crusher foundation is provided with an annular frame shell with support means capable of withstanding the higher than normal crushing forces, a hydraulic circuit capable of counterbalancing the crusher bowl while it is in a raised position to allow material to be cleared from a jammed crusher, and a mechanical anti-spin head bushing. A method is provided for increasing the production of conical crushers by altering head throw and diameter, increasing the power draw and increasing the internal volume of the crusher.
