    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.

    Sep 19 2007 · Higher breakage rates were noted with cylpebs than with balls. Furthermore it was found that the primary breakage distribution function is dependent on the feed size (i.e. non‐normalizable) but independent of the grinding media shape. The effect of grinding time on the product size distribution has also been investigated.

    process is to obtain mathematical relations between the size of the feed and the size of the product. Particles in the feed repetitively reduce their size due to the imparting energy of the grinding media which disrupts their binding forces. The size reduction is a result of the following three basic fragmentation mechanisms 25 46 .
