ABSTRACT:
A continuous type media mill for effecting in a particulate-containing substance, a reduction in size of the particulate. The mill includes a support and an elongate vessel mounted on the support. The vessel has a generally cylindrical interior. An inlet port to the interior of the vessel is provided as is an outlet port for the particulate-containing substance. Comminuting media is provided in the interior of the vessel, the media having a tendency to move toward the outlet port with the particulate-containing substance flowing through the vessel. A rotor extends centrally in the cylindrical interior of the vessel and along a majority of the length thereof. The rotor has a diameter substantially less than the inner cylindrical surface of the vessel to define a space therebetween. The rotor includes a plurality of blades spaced axially along the length thereof for flinging the media radially outwardly in response to a rotation of a driven shaft for the rotor. Structure is provided in the vessel for effecting a movement of the comminuting media toward the inlet port to the vessel in response to a rotation of the driven shaft to counter the aforesaid tendency of the media migrating with the particulate-containing substance toward the outlet port.
