CONE CRUSHER WITH ADVANCED HYDRAULIC SYSTEM Russian patent published in 2023 - IPC B02C2/04 B02C25/00 

FIELD: heavy engineering

SUBSTANCE: invention relates to crushing and grinding equipment, in particular to cone crushers, and can be used in technological processes in the construction and mining and processing industries. The cone crusher comprises a housing 2, an outer cone 5 and an inner cone 4 placed inside it, forming a crushing chamber between them. The vertical shaft 6 of the inner cone 4 is located in the eccentric assembly 7 connected to the electric drive 19. In this case, the vertical shaft 6, through the support bearing, rests on a damping hydraulic system, configured to adjust the position of the inner cone 4 and comprising a hydraulic cylinder body 14 with a main piston installed in it and with a chamber for hydraulic fluid, connected to a hydraulic accumulator and a hydraulic pump through pipelines. The improved hydraulic system comprises the main piston 13 installed inside the body 14 of the hydraulic cylinder, made in the form of an open glass, so that in its internal cavity there is additionally placed a locking block and a block of elastic elements 11, on which the movable piston, made in the form of a washer with a central hole, rests, configured to move inside the main piston, a thrust bearing is placed above the movable piston, on which the support bearing and the vertical shaft of the inner cone rest.

EFFECT: damping hydraulic circuit is compensated.
