APPARATUS FOR THE MIXING OF PARTICULATE MATERIALS

摘要

The invention provides a mixing apparatus (10) for mixing particulate materials in a desired ratio. The mixing apparatus (10) includes a mixing chamber (12), a main feeding arrangement (24) and a supplement feeding arrangement (36). The mixing chamber (12) mixes a main particulate material such as mealie meal with a particulate supplement material such as a powdery vitamin supplement. The supplement feeding arrangement (36) has a feed outlet through which the particulate supplement material is fed to the mixing chamber (12) at an adjustable selected rate. The supplement feeding arrangement (36) includes a rotary feed member, having a circumferentially extending series of axially extending feed chambers, such that operative rotation of the feed member successively delivers particulate supplement material from the respective feed chambers into the mixing chamber (12).
