Abstract:
    The hopper comprises a cylindrical side wall supported by an annular rolling ring so as to be rotatable about its vertical axis, and a funnel shaped bottom with a central outflow orifice controlled by a valve. To allow rapid removal of the rolling ring, the bottom is separated from the side wall and rests freely on an inner edge of the latter. An apparatus is provided for raising the bottom within the wall and for lifting the side wall slightly from the rolling ring.
