SYSTEM AND METHOD FOR HYDRAULICALLY REMOVING SOCKET FROM MAIN SHAFT OF GYRATIONAL CRUSHER Russian patent published in 2018 - IPC B02C2/04 

FIELD: desintegrators and crushing devices.

SUBSTANCE: group of inventions relates to means of crushing materials and can be used in cone crushers. Gyrational crusher comprises a fixed bowl, a crushing cone assembly, movable within the stationary bowl and forming a crushing gap between the stationary bowl and the crushing cone assembly, a main shaft having an upper end and an outer surface, an eccentric rotatable about the main shaft for communicating gyratory motion to the crushing cone assembly inside the bowl, a socket mounted on the upper end of the main shaft and a hydraulic separation system including at least one hydraulic groove located between the main shaft and the socket, and configured to detach the socket from the upper end of the main shaft. Hydraulic separation system for use with the above-mentioned crusher comprises at least one hydraulic groove made between the main shaft and the socket, and at least one hydraulic feed channel in fluid communication with the hydraulic groove for supplying the hydraulic fluid under pressure to the hydraulic groove.

EFFECT: group of inventions increases the ease of operation.
