Abstract:
A knife blade mounting assembly for use with a rotary drum to cut granular material, said knife blade mounting assembly comprising:a mounting frame defining a substantially semi-circular profile, said profile having a center region bounded by a first end region and a second end region; a plurality of knife blades combined with the mounting frame, each of said knife blades defining a plane, and each of said planes intersecting a line tangent to the mounting frame semi-circular profile at the location of the knife blade to form an angle of intersection, said angles of intersection being generally greater at locations on at least one of the mounting frame end regions than at locations on the mounting frame center region; the angles of intersection comprise a plurality of angles situated relative to one another and said angles progress generally from a shallow degrees of inclination at knife blades in the center region to steeper degrees of inclination at knife blades in the end regions.
