ABSTRACT:
A bulk-storage bin having a cylindrical wall is provided thereon with a helical chute having an inlet portion at its upper end whereby the bulk material is introduced into the bin and descends along the helical chute to be spread uniformly in the interior of the bin. The helical chute is provided as an inwardly open channel whose floor is a ramp which is inclined radially. According to the invention, in the transition region between the inlet and the remainder of the helical chute, the tangential inclination forms a continuous transition to the tangential inclination of the helical chute while the radial inclination in the transition region is always sufficient to permit the bulk material to slide along the ramp by gravitational force. This inclination thus is such that the total slope of the ramp is greater than the critical sliding angle (frictional re-ardation) of the piled material.
