Abstract

The gravity feed mixing of bulk materials is effected by removing partial quantities of the material at each of a plurality of vertically disposed levels, and passing the removed material through a series of funnels arranged vertically so that the material is admixed with the material passing from a higher level and fed to a lower level.
