Gravity Flow Spreaders are used to distribute dry grain in storage bins. The force of the falling grain against the curved vanes in the chute causes a slow, even rotation to provide a gentle distribution of grain. Gravity Flow Spreaders require no electricity. The chute is designed to divide the flowing grain and distribute it into four concentric rings in the bin. Fines and light material remain with the flowing mass of grain and are distributed away from the center of the bin. Two different models and options are available to provide spreading capacities from 200 to 10,000 bushels per hour (BPH) in storage bins ranging from 18' to 72' in diameter.
