GYRATORY CRUSHER HAVING AN ECCENTRIC SHAFT SUPPORTED BY PAIRS OF SPACED BEARING ASSEMBLIES Abstract A gyratory type crusher having a stationary frame and a generally conical crushing head rotatably mounted on an eccentric shaft so that the crushing head is gyrated upon rotation of the eccentric shaft. The stationary frame includes a concave which surrounds the crushing head and cooperates with it to form an annular crushing chamber. The eccentric shaft is rotatably supported at its lower end by a pair of vertically spaced radial roller bearings which are in turn axially slideably received in a cen- tral bore in the frame. The conical crushing head is rotatably supported on the upper end of the eccentric shaft by a pair of vertically spaced radial roller bearing assemblies which are axially slideably received within a bore in the conical head and which are received around the upper end of the shaft. The spaced bearing assemblies function to compensate for overturning moments applied to the crushing head to provide greater bearing wear and are axially slideably removable to facilitate replacement.
