[Also in Division B1] In a method of filling a hopper, Fig. 3, with particulate material and simultaneously mixing the material by a pneumatic conveyer system 40, 46, the material stream is directed into the lower region of the bin through vertical inlets 32, 33 to provide a vertical column of agitated material which mixes with a portion of the old material in the hopper. Material is supplied successively to the inlets 32, 33 arranged in separate conical base, portions 7, 8 so that a batch of material is distributed equally between the base portions. Distributer valves 41, 45 controlling the supply to the separate inlets 31, 33 may be automatically operated in succession by a cam mechanism and timer device (not shown) which may be set to operate at intervals between a few minutes or several hours according to requirements. For emptying the hoppers the material is fluidized by elongated aerators 12 extending upwardly of the sides of each base portion. Fluidized conveying ducts 24 controlled by valves 25 are arranged to carry material at equal rates from each base portion and are connected to a common outlet 30. In the event of material in one of the base portions having characteristics deviating from the normal, such as discolouration, the outlet flow may be reduced from that portion by partially closing one of the valves 25 so that the proportion of this material in the final delivery may be reduced to the required limits. A modification in which more than one silo is connected to a common outlet is described. Specifications 338,123, 674,395 and 804,014 are referred to.
