    At the feed mill, the feed particle size averaged 755 microns. With the hammer crushers installed on farms, the particles were of different sizes. As a result of grinding on the farm, particles were obtained with an average size of 1029 microns, at the feed mill - 730 microns. The economic effect of changing the particle size can be enormous.

    The size of both the feed surge bin and the feeder is based on the bulk density of the feed material. For materials with very low bulk densities, the feed chute to the mill should be carefully designed to prevent plugging. The bulk density can also be used to estimate the weight of the material bed in the grinding chamber during jet milling.
