Abstract

930,285. Grinding apparatus. GRUBBENS & CO. A.B. Feb. 22, 1962 [Feb. 22, 1961], No. 6952/62. Class 59. Grinding apparatus comprises relatively rotatable grinding members 1, 2 having opposed grinding surfaces each provided with one or more rings of depressions 4, or 5, concentric with the axis of relative rotation of the members 1, 2, the rings of depressions being displaced relative to one another such that an annular wall 6, or 7, at the side of one ring of depressions in one grinding surface is located opposite the ring of depressions in the opposite grinding surface, the wall 6, or 7, projecting into the opposite ring of depressions and the dividing walls 8, or 9, between the depressions in the opposite ring being provided with recesses 10, or 11, to accommodate the end of the wall 6, or 7. The end of the wall 6, or 7, may be interrupted to provide an annular series of teeth and the bottoms of the depressions of the ring thereof in the opposite grinding surface may be provided with cavities registering with the end of the annular wall. The end of the annular wall may be narrower than the base thereof. The opposed grinding surfaces may be flat, conical or cylindrical. One grinding member may be stationary and the other rotatable or both members may be rotatable either in opposite directions or in the same direction but at different speeds. The spacing between the grinding members may be adjustable.
