<p>The arrangement is intended for depositing (via 3,4) bulk material into, and removing it from, a dumping space in a covered (1b) or uncovered area with a cylindrical wall (1a). The material can be moved to an inner conical heap by a scraper assembly (11,13,14,17), which is rotatable about a central axis (12) and has a liftable scraper conveyor (11), and from there drops on to a further conveyor (10) via a central hopper (9) for removal. Apart from any support member which may extend through the space occupied by the heap, the entire assembly (11,13,14,17) is arranged above the heap. The assembly may be suspended from the roof (1b) structure.</p> |
