Abstract
Apparatus for measuring out material from a cold feed bin for use with a drum mix plant. The apparatus comprises a plurality of cold feed bins supported on a plurality of legs above a frame. Each leg of the bins rests upon a load cell which thereby measure the weight of the bin and material contained therein. Control circuitry connected to the load cells regulates belt feeders disposed below each bin which adjust the rate at which material is dispensed from each bin in response to the weight measured by the load cells to maintain a desired rate of weight reduction. A belt conveyor disposed below the belt feeders transports the dispensed material to the input of a mixing plant.
