CONICAL CRUSHER WITH IMPROVED ATTACHMENT OF CRUSHING ARMOR Russian patent published in 2016 - IPC B02C2/04 

FIELD: construction.

SUBSTANCE: invention is intended for technological processes of construction and mining industries. Conical crusher with improved attachment of the crushing armor includes housing (1), external crushing armor (2) and internal crushing cone (3) with crushing chamber between them. Housing is based on foundation (9) through elastic shock-absorbers (10). External armor is made in the form of a cone, rolling in the upper part in vertically oriented cylinder. External armor is fixed in the adjusting ring by an attachment system. Internal cone is arranged inside external armor on spherical support (4). Internal cone is driven by transmission from the engine. Circular hydro fixator of the external armor attachment system is based on an adapter ring. At least, one circular mounting slot (29) is made on the outer surface of the external armor cylindrical part. At least, two identical blocks (24) are inserted in the mounting slot from two opposite sides. Blocks are made in the form of the ring segment with complicated profile with angular size of the segment equal to 180° max.

EFFECT: invention provides rigid fixation of the crushing armor in the adjusting ring due to full contact of armor surfaces and adjusting ring with each other.
