The Mechanical Handling and Storing of Material

THE WAREHOUSING OE GRAIN 683 but all such gross impurities as string, sticks, or any large foreign matters, as well as a certain amount of dust, are eliminated in this preliminary process. Small Silo Warehouse Designed by Rudolf Dinglinger.—The illustrations, Figs. 976 and 977, illustrate a silo warehouse with a capacity of 700 tons of grain. The silos are built with masonry hoppers, whilst the upper part of the structure is of wood. The installation consists of an engine and boiler house on the ground floor, which also accommodates a receiving installation. The grain can be received at either side of the building, either from farmers’ carts or from self-discharging railway trucks, and can be carried from either side by conveyors to elevator j, which delivers it at the top of Fig. 977.

The elevator discharges in the first instance into an automatic weighing machine M, whence the grain can be conveyed to any of the nine silos. As the elevator has been erected nearly in the centre of the warehouse, it is possible to feed the silos without the aid of any conveying machinery. The contents of the whole of the silos can also be spouted back again to elevator J by means of cast-iron pipes in connection with the receiving band conveyors, which are also for the purpose of turning the grain over. Some of the silos are not quite so deep as the others, and are for the accommoda- tion of grain which has to be cleaned; from them it can be spouted to the cleaning machinery, from which it is removed to elevator j to be transported in a clean state into
