Abstract
1,263,764. Disc mills. N. PORA. 11 Sept., 1969, No. 44803/69. Heading B2A. The fixed and movable discs 26, 24, Fig. 1 of a disc mill 10 each comprise an annular ring 30, Fig. 2, fitted with alternate replaceable grinding blades 39 and spacers 40. An annular member 41 locked by screws 43 secures the blades in position. Each blade may be straight or of arcuate shape and has saw-type teeth 51 whose pitch is finer towards the circumference of the disc. The blades of the fixed and movable discs oppose one another so as to cross. The spacers may be replaced by a filler, e.g. white metal or plastics. In operation, the gap between the discs is varied by actuation of a rod 18. Material is distributed about the disc surface by impellers 28 which also cause an airflow through the mill. The blade 24 may be driven in an anti-clockwise direction, Fig. 2, to produce a smoother grinding action. Further, to asist coarse grinding, crescentshaped grooves may be cut into the face formed by the blades 39 and spacers 40, and to assist fine grinding a band of fine-toothed circular blades may be provided around the periphery.
