CONE INERTIAL CRUSHER WITH A DEVICE FOR FIXING UNBALANCE Russian patent published in 2018 - IPC B02C2/00 

FIELD: machine building.

SUBSTANCE: invention relates to heavy engineering and can be used in technological processes for the construction and mining industries. Device contains a casing supported on the foundation through elastic shock absorbers, an outside cone and located inside it on a spherical support an inside crushing cone, forming a crushing chamber among themselves. On a drive shaft of the inside crushing cone, with the help of a slide bushing, an unbalance is mounted with the possibility of adjusting its center of gravity relative to an axis of rotation. Slide bushing of the unbalanced mass is connected to a transmission plate clutch, which is connected to a gear wheel and an antidebalance, which in turn are mounted on the slide bushing in such a manner that said gear, antidebalance and slide bushing form a single movable "dynamic assembly" which is through a cover plate mounted on a fixed axis of rotation supported on a flange. Flange is rigidly fixed in a bottom part of a crusher housing. Crusher housing has at least one service hatch. Crusher comprises at least one device for fixing unbalance, which is fixed to the crusher housing, includes a carrier post with upper and lower sliders and two arms connected to each other by a remote insert.

EFFECT: simplifies and increases the reliability of the device for fixing unbalance.
