Abstract: 936,821. Feeding to grinding mills. HARDINGE CO. Inc. Jan. 13, 1961 [Jan. 19, 1960], No. 1484/61. Class 59. [Also in Group XXX] A method of providing a mixture of solid material for grinding mills having a substantially constant average proportion of various size ranges comprises the steps of dropping a mixture of various sizes of the material to form a piled mass at such a rate that a slope is formed which extends downward and outward from the top of the mass, thereby to effect a substantial segregation of the entire mass generally into several different size ranges which in relation to each other are relatively fine and relatively coarse and said different size ranges are disposed into different general zones within said mass, withdrawing said different size ranges of material from spaced locations respectively beneath the bottom of each of said general zones at a selected rate, and recombining the withdrawn material to produce a mixture having substantially the same average proportion of various size ranges of material as in the material delivered to said mass over an extended period of time. As shown, material is fed to a bin 64 to form a pile having zones of coarse and fine material and is withdrawn through openings 54, 56 in the bottom 46 of the bin, material withdrawn through the openings passing by way of auxiliary conveyers 60, 62 to a central conveyer 58. The motors driving the conveyers are operable successively and at selected rates by means of an electric circuit, Fig. 14 (not shown), which includes a sequence switch. The. openings are arranged in circular rows. In a modification, Fig. 5 (not shown), the bin is omitted and the piled mass is formed on a base-plate.
