Abstract
A primary classifier (300) particularly suited for use in a bowl mill (10) of the type that is employed for purposes of effecting the pulverization of materials such as coal is provided by the present invention. The primary classifier (300) includes a vane wheel portion (360) affixed to the periphery of the rotatable grinding surface (14) of the bowl mill (10) so as to extend circumferentially around the entire interior of the substantially closed separator body (12) of the bowl mill (10). The primary classifier (300) further includes a low profile deflector portion (380) mounted within the interior of the substantially closed separator body (12) of the bowl mill (10) in closely spaced relation to the circumference of the rotatable grinding surface (14) at an elevation below the elevation of the grinding journal openings (205) and so as to extend continuously without interruption about the entire interior of the substantially closed separator body (12) of the bowl mill (10).
