Abstract
The apparatus is for batching different flowable materials, e.g. “small chemicals” in the correct proportions by weight. A plurality of bulk material supply stations 14 are connected to a compact, space filling array of weighing hoppers 18 via relatively short screw 20 and/or vibratory conveyors 22. As shown, two conveyors serve each weighing 10 hopper 18. The weighing hoppers 18 are mounted upon off-centre load cells 24 and discharge into a containment cone 36 and a discharge funnel 37 for leading the weighed material batches into bagging apparatus 38.
Claims12
Apparatus for combining different flowable materials into batches in predetermined proportions by weight comprising a plurality of bulk material supply stations, a plurality of weighing hoppers, and a plurality of conveyors extending between the bulk material supply stations and the weighing hoppers, wherein the weighing hoppers have an upper end for receiving material from the conveyors, and a discharge end, the weighing hoppers being grouped together in close proximity, outwardly arranged side walls of the group of weighing hoppers sloping inwardly and downwardly, so that material emerging from the discharge ends is directed along convergent discharge paths, the weighing hoppers each comprising a hinged discharge door over which in the open position the material flows thereby forming part of the convergent discharge path.
