ABSTRACT:
A pulverizing bowl mill embodying improved air deflector means and particularly suited for use in effecting the grinding of material. The subject bowl mill includes a substantially closed separator body in which a grinding table is supported for rotation. A plurality of grinding rolls are supported within the separator body and cooperate with the rotating grinding table to effect the grinding of the material, which is disposed upon the grinding table. Air deflector means corresponding in number to the number of grinding rolls are mounted within the separator body so as to be located in juxtaposed relation to the inner surface of the separator body and so that an air deflector means is interposed between each pair of adjacent grinding rolls. An air supply means suitably formed in the separator body is associated with each of the air deflector means. Each of the air supply means is operable to supply air from an external source thereof therethrough to the interior of the separator body. A material supply means operable for supplying the material to be ground in the bowl mill is suitably formed in the separator body. Each of the air deflector means is operable to concomitantly perform both the function of effecting a leveling of material disposed on the rotating grinding table so as to present a uniform layer of material to the grinding roll located immediately downstream thereof and the function of encompassing all the air flow provided by the air supply means associated therewith for purposes of effecting the subsequent deflection thereby of this air flow over the rotating grinding table.
