Abstract
A reversible granulator includes double-edged cutting blades mounted on a rotor with each of the edges on an opposite side of the cutting blade. A pair of fixed bed knife members each have a pair of peak cutting edges with an intervening clearance space. One peak cutting edge in each bed knife cooperates with one blade cutting edge when the rotor is rotated in one direction to cut material, while the other peak cutting edge cooperates with the other blade cutting edge upon rotor rotation in the opposite direction.
