GRINDING DEVICE Russian patent published in 2018 - IPC B02C13/14 

FIELD: desintegrators and crushing devices.

SUBSTANCE: invention relates to the materials mechanical grinding devices. Device (10) comprises at least rotor (16, 18), which is designed with possibility of rotation about vertical rotation axis (R), disposed in grinding chamber and having impact means (22, 24), passing, at least during operation, inside the grinding chamber in the substantially radial direction. Grinding chamber is surrounded by circular cylindrical and / or conically expanding grinding chamber wall (12). Grinding chamber has supply side (15) on its upper end face and output side on its lower end face. At its lower end the rotor (16, 18) is held in fixed stationary position relative to the device bearing base (20), and the grinding chamber wall is supported by the bearing base. Grinding chamber wall is kept in the rotor axis (R) direction by means of lifting device with the possibility of height adjustment relative to the bearing base (20). Lifting device (36) has an operating position, in which the grinding chamber wall lower edge is located in close proximity to the bearing base (20) or the part connected thereto, and the maintenance position, in which the grinding chamber wall (12) lower edge (32) is raised vertically above at least one of the impact means (22, 24).

EFFECT: enabling the possibility of the grinding device impact equipment simple maintenance and simple replacement.
