Process and apparatus for screening a stream of bulk material

Bulk-material silo with expansion chamber

A device for loading bulk material from a stationary source to a filler pipe located at a chosen spot within a predetermined line of travel. The device comprises a loading hopper which is shiftable along the line of travel and exhibits, at its lower end, a filling mechanism and a conveying pipe, feeding the bulk material to the loading hopper, which conveying pipe is pivotably mounted at its end receiving the material and the outlet end of which opens out into the loading hopper. The loading hopper is closed off at the top by a cover, which exhibits an opening receiving the outlet end of the conveying pipe. The cover is rotatable in relation to the loading hopper, the opening being eccentrically disposed. Expediently, the rim of the loading hopper and the cover are circular.

Device for loading bulk material

The bulk material silo has a venting bottom containing a fiber layer (4). To compensate the difference in flow-off resistance, which differs with the distance of material from the discharge (6), it is provided that the fiber layer differs in flow resistance (10) along the path of the material toward the outlet (6), specifically having a lower flow resistance in regions further away from the outlet.
