BODY FOR GYRATORY CONE BREAKER AND ALSO GYRATORY CONE BREAKER Russian patent published in 2010 - IPC B02C2/04 

FIELD: mechanics.

SUBSTANCE: invention relates to inner body for gyratory cone breaker, and also to gyratory cone breaker itself. Inner body for use in gyratory cone breaker includes inner body designed for contact with material, which is fed in upper part of breaker and is subject to crushing, and crushing of this material in crushing gap with external body, at the same time inner body rotates in process of crushing around its own central axis (CL) in the first direction (R1). Inner body has at least one additional breaking surface, which in horizontal projection and when viewed in the first direction (R1) has reducing distance to specified central axis (CL). Additional breaking surface at the first end, which is located near output end of additional breaking surface relative to the first direction (R1), is arranged with formation of the first distance (D1) from central axis (CL), and at the second end, which is arranged near input end of additional breaking surface relative to the first direction (R1), is arranged with formation of the second distance (D2) from central axis (CL). The second distance (D2) is more than specified first distance (D1), so that objects (S) may be introduced between additional crushing surface and external body at specified first end to compress near specified second end between additional crushing surface and external body.

EFFECT: invention makes it possible to reduce blocking or clogging of breaking gap, accordingly, to eliminate necessity to perform manual cleaning of breaking gap and therefore increase efficiency of gyratory cone breaker.
