Intro to Size Reduction
Pneumatic Discharge Hammer Mills The grinding mechanism of this group is quite similar to the gravity discharge hammer mills. However, the pneumatic mills typically use a thinner hammer and the interior wall of the grinding chamber features a ribbed liner plate. This plate has a washboard effect on the material, and works in unison
TECHNICAL BULLETIN
In place of roller drafting, a simple wire or pin-covered cylinder several inches in diameter and about an inch wide is used (Exhibit 6). This beater, or combing roll, as it is normally referred to, works just like a card lickerin; it is, in fact, covered with metallic card wire, or possibly steel pins. The rotational speed of a combing roll ...
