Abstract

A gyratory crusher for crushing material having a frame mechanism including a lower frame portion; a crusher head having a bottom surface; a mounting mechanism for pivotally and gyrationally mounting the crusher head on the lower frame portion wherein the mounting mechanism includes a plurality of hydrostatic bearings configured to form a sliding engagement with the bottom surface of the crusher head to operatively support the crusher head; a drive train configured to operatively connect said mounting mechanism to an external power source; and a self-contained lubricating system for operatively lubricating the mounting mechanism and the drive train, wherein the self-contained lubricating system includes a flow divider configured to separately distribute lubricant to each hydrostatic bearing of the plurality of hydrostatic bearings wherein the flow divider is further configured to operatively provide lubricant to each sliding engagement of the plurality of hydrostatic bearings such that the crusher head is slightly elevated from the plurality of hydrostatic bearings, a monitoring system for monitoring the volume rate of lubricant flowing through the flow divider wherein the monitori…
