A rotary collider air mill apparatus that uses accelerated air moving at high velocities as the primary reduction medium is described. The apparatus produces turbulent air currents and shear waves within a polygonal housing whereby solid particles introduced into the housing repeatedly collide with each other and are fractured into smaller particles. An exemplary rotary collider air mill apparatus may include a polygonal housing having a front plate and a back plate and 5 or more side plates, a drive shaft passing through the central portion of the polygonal housing, a sprocket mounted on the drive shaft and having arms extending radially from a central hub, and 3 or more blade sections attached to the arms. The rotary collider air mill apparatus is scalable upward or downward in sizes ranging between 12 inches and 144 inches in diameter with the housing and internal mechanisms sized proportional to one another. |
