FIELD: mining.
SUBSTANCE: invention is related to devices for enrichment of ores. Abrasive mill comprises rotary grinding cup surrounded with wall of working cavity, where milling rolls revolve. Annular space is limited with edge of grinding cup and wall of working cavity. Mill comprises at least one outlet hole for ground material. Under edge of grinding mill there is a separating device, which is connected to annular chamber for supply of separating air flow. Separating device, to which ground material is supplied under gravity, has at least one outlet for fine fraction and one outlet for coarse fraction.
EFFECT: rejection from mechanical or pneumatic transportation of ground material to separation system, and also energy saving.
