ABSTRACT:
An arrangement for storing and removing bulk material in a round pile, in which a truss is rotatable about a vertical axis on a substructure. The truss carries a material depositing belt and a bulk material receiver which is pivotable in a vertical direction. A counterweight on the truss balances weight. The substructure is hopper-shaped. The truss is mounted on the substructure by a bearing, and rollers carry the truss which runs on the substructure. The bulk material receiver is in the form of a drag that conveys to a hopper of the substructure. This hopper has a bottom with a conveying medium under which a conveyor belt runs. The bearing has a large diameter annular track that is elevated on posts on the substructure. A rotatable plough located at the bottom of the hopper is the single conveying element on the hopper bottom.
