The present invention relates to a system for unloading a tank of pulverulent or granular products, particularly a tank carried by a vehicle. The lower longitudinal walls (6d and 6e) of the said tank (6) slant towards the bottom of the said tank (6) and the said system consists of at least one hatch (11) in the bottom of the said tank (6) which emerges over a conveyor intended to transport the product contained in the said tank (6) towards a discharge outlet. According to the invention, the conveyor (10) consists of a longitudinal trough (7), in the bottom of which are mounted, side-by-side, two Archemedean screws (9a and 9b). <IMAGE>
