Abstract

313,845. Loesche, E. C. Jan. 7, 1929. Roller-and-ring mills.-In a mill comprising a rotatable milling dish f , Fig. 1, and stationary rolls l, preferably applied through the medium of springs m<1>, and an arrangement for carrying air from the lower part of the mill to the upper part, the milling dish f is provided on its periphery with a rim or trough practically open at the top and having a lower surface inclined downwardly in the direction of rotation so that it picks up and returns to the dish the material which falls over the rim. The peripheral trough is divided into segments p' - - - p<6>, Fig. 2, the bottoms r<1> - - - r<6> being inclined in the direction of rotation and terminating a short distance from the end of each segment so as to leave orifices k<1> - - k<6>. Air enters tangentially of the dish by a volute passage b and the trough is arranged near the casing at a<1> so as to prevent the passage of air. The troughs act as scoops and throw the material upwardly so that the fines are carried off by the air blast and the heavier particles fall back into the dish. The periphery of the trough may be perforated with holes for the access of air, and the peripheral edge of the trough at a<1> may be inturned to divert the large particles on to the dish. The trough may be outwardly flared and the lower and outer surfaces of the compartments may be constructed in the form of deflecting blades.
