ABSTRACT:
A helical distributing chute conveyor for a receptacle for transferring loose varied fragile chemical and pharmaceutical products, particularly of the granular or pulverulent type. This chute conveyor, placed in a receptacle, comprises helical chute paths developed about a vertical axis; each chute path, whom cross section is straight, is inclined transversely towards the vertical axis, the angle of inclination of the chute path being calculated such that, whatever their size, the particles of material transported deviate towards the vertical axis when the centrifugal force which originally keeps them on the chute path cancels out or drops below a critical value.
