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.
