CONICAL GRINDER Russian patent published in 2014 - IPC B02C2/04 

FIELD: process engineering.

SUBSTANCE: invention relates to grinding, particularly, to conical grinders. Grinder 10 comprises grinding cone 22 fitted on vertical shaft 18, first lining 30 secured to said cone and housing 12 whereto second lining 32 is secured. Second lining 32 and first lining 30 make the working clearance 34. Support piston 36 is arranged inside the cavity 40 of shaft 18 to displace vertical therein for adjustment of working clearance width. Eccentric 20 runs in at least one radial bearing 42 about shaft 18. Grinder 10 comprises oil line 44 arranged in said cavity 40 to extend via piston plate 37 of piston 36 for feed of lubing oil to chamber 46. The latter is arranged, at least partially, in cavity 40 above plate 37 of support piston 36. Note here that chamber 46 for lubing oil is communicated with radial bearing 42 via channel 50 in shaft 18.

EFFECT: decreased mechanical abrasion and radial bearing wear.
