FIELD: agriculture.
SUBSTANCE: mill comprises a loading (1) and an unloading (2) devices. On the drive shaft (3) a working chamber is mounted in the form of coaxially arranged spirals (4). The spirals have opposite coiling. The channel for pouring the material (5) from one spiral to another in a certain section has a zone with holes (7) for selecting the crushed material. In the inner space of the spirals there are grinding balls (6). In the zone of the unloading device the side surfaces of the spirals are attached to the conical chambers (8). One of the chambers has holes (10) on the side surface and communicates through the branch pipe (11) with the loading device. For directing the material to the unloading device the inclined trays (13, 14) are mounted under the working chamber.
EFFECT: invention has a simplified structure and ensures a high degree of grinding.
