MIXING DEVICE FOR BULK IMPREGNATION OF PARTICULATE MATTER BY A BINDER

摘要

A device for mixing particulate matter and liquids comprises a rotatable central shaft passing through a stationary particle feed hopper and supporting a perforated rotatable plate and incorporating a liquid feed conduit terminating at an atomizer, a spray chamber, a rotating assembly linked to the rotating plate and made up by an agitator located below said spray chamber and by a conically-shaped particle catching and spreading tray which discharges the coated particles into a mixing chamber fitted with blades and rotating in the opposite direction to the said rotating assembly, whereby excellent bulk impregnation of said particulate matter is obtained.
