Abstract
A beater mill comprising a cylindrical housing which accomodates a rotor carrying at least two arcuately spaced groups of beaters, the beaters from group to group being axially offset, the cylindrical jacket of the housing being formed as a peripheral sectional screen, an axial inlet for material to be milled being provided adjacent the rotor axis, the rotor arms being formed as fan blades and the said inlet including a distributor means for the air and material taken in through the inlet.
Claims3
A beater mill comprising
- a cylindrical housing,
- a rotor mounted for rotation in said housing, said rotor including
- a hub and
- at least two fan blades arcuately spaced about the rotor axis, said fan blades each having
- a plurality of beaters thereon, the beaters of one of said fan blades being axially offset with respect to the beaters of another of said fan blades,
- said cylindrical housing including a peripheral screen area, the outer portions of said fan blades having an axial width corresponding to the width of said peripheral screen area, the inner portions of said fan blades having a reduced axial width and forming an axial recess in said rotor,
- inlet means for delivering both air and solids to said housing including an inlet duct terminating within said recess of said rotor coaxially therewith, a distributor mounted within said recess coaxially with said inlet duct and said rotor and for axial adjustment relative to said rotor, said peripheral screen area including a plurality of arcuate sections, each section being rigid and having axially-extending flanges, and mounting means on said housing including axial slots for carrying the flanges of said sections in sliding relationship.
