FIELD: construction and mining industries.

SUBSTANCE: invention relates to cone crushers and can be used in the technological processes of the construction and mining industries. The inertial cone crusher contains a housing 1, an outer 2 and an inner 3 crushing cones with a crushing chamber between them. The body 1 rests on the foundation 9 through elastic shock absorbers 10. The outer cone 2 is made in the form of a cone that passes in the upper part into a vertically oriented cylinder and is fixed in the adjusting ring by means of a fixation system consisting of at least three latches. The inner cone 3 is placed on a spherical support 4. The inner cone 3 is driven by the transmission from the engine. Each retainer includes a cracker 16 and a system of its fastening from an insert 27, a spherical washer 19 and a bolt 25. On the outer side of the outer cone 2, a collar 28 is made in the form of an outer circular protrusion. The inner diameter of the adjusting ring 17 has spherical recesses 32 with holes 8 located along the upper edge of the circumference of the ring and corresponding to the number of retainers.
