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.

A method of pelleting animal feeds having improved production efficiency with good pellet quality comprising: (a) heat conditioning the feed at a moisture level of between about 17 to 21% by weight and a temperature above about 200°F. (b) pelleting said feed by passing through a die having a compression and discharge side, and at least one die hole extending through said die, having a countersink on the compression side, said die hole having a working section for pellet formation, said section having a diameter that defines pellet size and a length that defines the effective thickness for the die hole, said die hole having a ratio of effective thickness to countersink diameter which is at least about 1.8 to 1 and a countersink diameter which is at least about 137% of the working section diameter.
