Abstract
A regrind deflector for an apertured screen in a hammermill has a plate extending along substantially the entire length of the screen and having a straight surface smoothly blending to a curved surface, the straight surface beginning at an inner surface of the screen and substantially tangent thereto and extending outwardly to the curved surface which curves back inwardly to the inner surface of the screen and intersects therewith at an angle of less than 90 degrees. The number of deflectors required depends on hammermill size and operating conditions as well as characteristics of the feed material to be processed.
