Abstract:
    To ensure the vertical and symmetrical fall of the charging material from a hopper onto a distribution spout the discharge valve of the hopper and the valve of a chamber feeding material to the hopper are regulated in such a way as to form a barrage in the base of the hopper. To control the formation of this barrage and ensure that it will be maintained throughout a charging phase the hopper and the chamber are weighed separately, signals being produced for the control of the dosing valves. In a preferred embodiment of an installation for the performance of this process the hopper (70) is rotated in order to reduce the segregation of the particles.
