FIELD: process engineering.
SUBSTANCE: set of inventions relates to crushing hardware and comprises gyratory crusher, support and gyratory crusher cam. Cam running about fixed main shaft (20) makes movable cone assembly gyrate to crush the rock inside discharge slot (34). Movable cone lower bush contacts with cam outer surface. Said cam has contact island to increase contact between said cam and said lower bush at no-load operation. Said contact island has contact surface recessed relative to cam outer surface to increase contact at idling not affecting a full contact between said lower bush and cam outer surface in crushing at full load.
EFFECT: better contact between the cam and movable cone lower bush at idling.
