At the bottom of the bin a rotatable screw feeder (8) is provided, said screw feeder (8), with a front portion, projecting through an opening in the front end portion (5) and extending into a compressing device protruding from the outside of the front end portion (5), said compressing device being composed of a cylindrical tube (12) and a tapering tube portion (13) protruding from said tube (12). Concrete or other material that by the screw feeder is transported out of the interior of the bin is compressed in the tapering portion (13) before the material reaches an outfeed opening (14) at the outer end of the tapering tube portion (13).
