Abstract

An elongated stockpile of flowable solid material with two halves disposed at the opposite sides of a longitudinal vertical symmetry plane is accumulated by transporting the material feeding portion of an elongated conveyor in the interior and lengthwise of the upper slope of a mansard-shaped shed together with a manifold having two ducts which receive flowable material from the feeding portion and flank the conveyor. The ducts discharge material onto two discrete transverse conveyors which are shiftable so that their discharge ends move nearer to or further away from the symmetry plane. The transverse conveyors are movable with the manifold lengthwise of the upper slope and are mounted on a gauntry which travels along rails. The transverse conveyors discharge streams of flowable material which forms elongated piles, first on the floor and thereupon on the layer of flowable material which is formed by the piles covering the floor at both sides of the symmetry plane. The transverse conveyors are shifted upon completion of each forward and each return stroke of the gauntry so that successively deposited piles are staggered with reference to previously deposited piles.
