Apparatus And Method For Coating Particulate Material

摘要

A method and apparatus are defined for coating a particulate material. The apparatus includes a mixer having a mixing chamber. A quantity of particulate material is fed into an inlet of the mixing chamber. An agitator is provided for mixing and conveying the particulate material. A feed system is also provided for delivery of a coating into the mixing chamber. The coating is delivered as an atomized spray directed at the mixing particulate material within the mixing chamber. A controller is provided for adjusting the flow of the coating into the mixing chamber based on the volumetric feed rate of the particulate material.

1. An apparatus for coating a particulate material comprising:
a mixer having a mixing chamber; means for incrementally feeding the particulate material into the mixing chamber; sensors determining the incremental volumetric flow of particulate material feed into the mixing chamber; an agitator provided in the mixing chamber, the agitator mixing and conveying particulate material from an inlet to a discharge outlet; a coating feed system for delivery of a coating into the mixing chamber during mixing by the agitator, the system directing an atomized spray at the mixing particulate material within the mixing chamber; and a controller for continuously adjusting the flow of the coating into the mixing chamber based on the volumetric feed rate of the particulate material determined by the sensors.
