Abstract
An improved pellet mill die is disclosed which has improved production efficiency without a corresponding loss in pellet quality or durability. The die comprises a compression side, a discharge side, and a plurality of die holes extending through the die. The die holes have a countersink on the compression side, and preferably at least a portion of die holes have a relief section to thereby define a working section of the die hole where the pellet is formed, and an effective thickness for the die holes which is preferably less than the distance between the compression and discharge side of the die. The die has a ratio of effective thickness to countersink diameter of at least about 1.8 to 1 wherein the countersink diameter is at least about 137% and preferably between about 137-159% of the working section diameter.
