FIELD: grinding.
SUBSTANCE: grinding device (1) includes: container (30) with outlet (30-1) for grinding material; first grinding tool (11) and second grinding tool (14), wherein first grinding tool (11) can be rotated relatively to second grinding tool (14) around axis (R) of rotation, so that grinding material can be ground in grinding gap (20) between first grinding tool (11) and second grinding tool (14), wherein second grinding tool (14) has inlet channel (14-1), which is limited with section (16A) of a wall, passing around axis (R) of rotation, and through which grinding material can be supplied to grinding gap (20), wherein second grinding tool (14) can be moved towards axis (R) of rotation relatively to first grinding tool (11); sealing cuff (40) located between container (30) and second grinding tool (14), having passage channel (40A), through which grinding material can fall out of container (30) to inlet channel (14-1) of second grinding material (14). The sealing cuff is located stationary relatively to container (30) in such a way that first ring-shaped section (41) of the sealing cuff, which limits passage channel (40A), is in contact with container (30) and has overlap (U) towards axis (R) of rotation with section (16A) of the wall of second grinding tool (14). The sealing cuff has second ring-shaped section (42), which is connected to first ring-shaped section (41) with at least one connecting section (43) made in the form of an elastically deformed spring element, and which rests against support surface (AF).
EFFECT: obtainment of a grinding device.
