Abstract
A mill includes a housing with a first end portion, a second end portion, and a lateral area disposed therebetween. The housing includes a raw material inlet, an air inlet, a recirculated material inlet, and a material outlet. An impeller is supported by the housing and includes a shaft disposed along the longitudinal axis of the housing, with a plurality of curved blades. A method for milling includes receiving a material of a first size range, introducing the material to an apparatus via a first inlet and introducing air into the apparatus via a second inlet. The method also includes agitating the material via an impeller, where the agitation reduces at least some of the material to a second size range by the time the material reaches an outlet of the apparatus. The processed material is delivered to subsequent processing operations.
