11QULK bodywork for animal feeding 13 stuffs is claimed by F. E. Callow (Engineers), Ltd., Kirkby Industrial Estate, Liverpool, the builders, to be the only kind of its type which will pneumatically discharge flake maize. It is made up of individpal container sections. Each has a capacity of 2 tons, and up to four may be placed on the platform of a fourwheeled lorry.
The containers discharge through a slide into a specially developed conveyor fitted under the platform. The conveyor moves the material to the rear of the vehicle to a rotary blower valve, which is driven by an Edbro hydraulic motor, which also supplies power for the conveyor: The rate of delivery of the material into the air stream can be regulated by means of a needle valve fixed at the rear of the vehicle. This controls the speed of the conveyor and cnahles the operative to avoid blockages.
Throughputs, in tons per hour, which are stated to have been obtained by the outfit when delivering up to 40 ft. are: grain, 10; pellets, 12; cubes, 6; meals, 15; flour, 27. Under exceptional conditions, a delivery rate of 18 tons per hour with pellets has been obtained. The makers further claim that a vehicle of this type is capable of delivering and discharging 80 tons of cattle food per week with one operative—a rate about double that of a normal vehicle. Users of the Callow design include Messrs. Walmsley and Smith, Barrow-inFurness, flour and provender merchants. and Messrs. S. and E. Johnson, Darley Dale, fiake-maize manufacturers.
