FIELD: process engineering.
SUBSTANCE: invention relates to disintegration and crushing of rocks and ores. Vertical centrifugal crusher comprises cylindrical housing 1 with top loading 6 and bottom unloading 7 holes, coaxial working bodies - an external stationary working body 2 and a rotating internal fixed working body 3. Working elements of one working body are located between similar elements of another working body and form radial stepped disintegration working chambers. The grinder allows adjusting the angle of discharge stream of crushed material relative to the central axis of the housing 1 to retain under-grinded particles in the working chamber, the width of which is adjusted by means of a set of washers 5.
EFFECT: provides ability to adjust the grind size of grind products depending on the strength and size of the grinded material.
