Apparatus for the uniform distribution of material issuing from blast pipe lines has a terminal distributor arranged directly on the discharge end of a horizontal or slightly rising conveyor pipe line, with the distributor including a drivable and swingable discharge trough. The discharge trough is mounted for oscillation, in a predetermined adjustable range, about the axis of the conveyor pipe to direct the material at an angle to the axis either laterally or downwardly. The conveyor pipe includes an intermediate section and a terminal section having a diameter larger than that of the intermediate section. A guide rail extends above the material receiving area and mounts the terminal section for reciprocation parallel to its axis with the major part of its length being telescopable over the intermediate section. The terminal section may be designed as an elongated hood with a detachable bottom wall which is detached from the hood as the terminal section is retracted and which is attached to the hood as the terminal section is extended.
