PURPOSE:To allow ore to be fed from an upper part to a lower part under a transversely uniform condition, by forming a shoot as a diverging sector which is arcuate in cross-section, i.e., is swollen at its central portion. CONSTITUTION:A shoot 3 serves to feed ore from an ore outlet 1 to a wide receiving section 2, and subsequently to the next stage. The shoot 3 is so formed to a sector as to diverge from the upper portion to the lower portion, and the upper surface of the shoot 3 is so formed as to define a part of a conical surface as depicted by a phantom line C and to be arcuate in vertical cross-section. With this arrangement, the ore O fed from the ore outlet 1 may be slidden down and radially diverged from the upper portion of the shoot 3 toward the lower portion thereof, and thus may be fed out uniformly along the transversely direction from the lower portion of the shoot 3 to the receiving section 2. |
