Abstract
Prior pulverizing apparatus which use rotating blades to pulverize the material require air as a pulverizing medium. The present invention uses a rotor structure which can operate in a vacuum if necessary.
Claims10
A method of non-impact pulverizing of material comprising:
- i) providing an apparatus for pulverizing material comprising:
- a) a housing having a hollow interior and an input conduit and an output conduit communicating with said hollow interior;
- b) a cylindrical rotor mounted for rotation in said hollow interior of said housing, and comprising a hollow hub, two circular parallel discs mounted coaxially on said hub, a plurality of flat blades perpendicular to said parallel discs extending radially from said hub to a point adjacent the outer circumference of said circular discs between said discs, said hub having an aperture opening to the hollow interior of said hub and a plurality of openings in said hub between said blades communicating between the interior of said hub and an area between said blades;
- c) power driven means for rotating said rotor;
- wherein said input conduit is adapted to direct said material to be pulverized to said hollow interior of said hub;
- ii) rotating said rotor at high angular velocity;
- and
- iii) introducing said material into said hollow interior of said hub;
- whereby said material is substantially pulverized prior to any impact with said housing.
