    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.
