<p>The arrangement (1) has a circular bearing surface (3) over which a dome-type roof (4) is clamped. A hollow column (5) is extended from a bearing face to the roof for supporting the roof. A bulk material supplying unit supplies the bulk material via the hollow column. The bulk material is pneumatically conveyed from a lower end (7) of hollow column to an upper end (8) of the hollow column by a feeding line (6), where the upper end turns toward a roof and the lower end turns toward the bearing surface. The bulk material is conveyed at an upper end of the arrangement.</p> |
