Abstract: A mill for effecting in a particulate-containing substance a reduction in size of the particulate. The mill includes a support on which is rotatably mounted a vessel having a comminuting media contained therein. A shaft extends centrally of the vessel and is fixedly secured thereto to rotate with the vessel. Plural planar discs are secured to the shaft and extend in a plane transverse to the axis of rotation of the vessel. Planar blades are secured to both the disc and to the vessel so that the vessel, shaft, discs and blade means rotate as a unit. A spacing is provided between the radially outermost extremity of the blade means and the discs and the internal surface of the vessel. Deflector members are oriented in the spacing for deflecting media radially inwardly into engagement with the discs and blades so that the disc and blades can accelerate the comminuting media radially outwardly in response to a rotation of the vessel and connected discs and blades.

Abstract: A mill for effecting a reduction in size of a particulate in a particulate-containing substance wherein the mill includes a support structure, an elongated vessel rotatably mounted on the support structure about an axis of rotation as well as a drive motor therefor. The mill further includes an inlet port and an outlet port for allowing the particulate-containing substance to flow through the vessel structure. An elongate and generally cylindrical, hollow rotor body is provided and extends centrally of the vessel structure and along a majority of the length thereof. The rotor body is fixedly secured to the vessel structure and rotatable therewith. A plurality of cavities are disposed in and equally spaced about the cylindrical peripheral surface on the hollow rotor body so that each cavity opposes the inner surface of the vessel structure.
