Abstract

See full text

A gyratory crusher for crushing material having a frame with a lower frame portion; a crusher head; a mounting mechanism for pivotally and gyrationally mounting the crusher head: and a thermal relief system for operably transferring thermal energy from the mounting mechanism to the lower frame portion, wherein the thermal relief system includes at least one collar in thermal communication with the lower frame portion and a self-contained circulating system configured to operatively circulate coolant through the at least one collar. The thermal relief system may be configured to operatively provide a cooling system for cooling lubricant being used to lubricate the mounting mechanism. The coolant may be a lubricant such that the self-contained circulating system may be configured to operatively circulate the lubricant simultaneously through the thermal relief system and the mounting mechanism. Alternatively, the self-contained circulating system may be configured to operatively circulate lubricant through the mounting mechanism, and, after the lubricant reaches and surpasses a pre-selected temperature, to also simultaneously circulate the lubricant through the thermal relief system. A bypass valve arrangement is provided to operatively bypass flow of the coolant or lubricant through the at least one collar as the temperature of the coolant or lubricant is below a pre-selected temperature.
