Abstract (en)

[origin: EP0829303A1] The mill has a rotary grinding ring (10) whose cylindrical inside surface forms a grinding track (14), against which a drum (13) is pressed. An inlet and outlet are provided for the material, together with a gas inlet and exhaust. The grille (29) of a sieve-cage is mounted inside the ring and between the track and the drum. The ring can be mounted between end walls (15,16) forming a housing in conjunction with it. Material flows in via one or more openings (18) in one or both walls, and out via others and/or lateral bends (19) above the drum. The bearings for the latter can be outside the walls, and scrapers can be fixed to the latter, bearing against the track (14).
