Screen classifying cutter downsizes raw materials into uniform particles at University of Maine's Process Development Center. In one alternative energy project, perennial grasses and hay are pelletized to make compressed biofuel pellets.
Cutter reduces material into uniform particles with minimal fines or imperfections, and with little or no heat generation.
The rotor contains dozens of cutter tips attached to a helical array of staggered holders, to continuously shear oversize materials against twin, stationary bed knives with minimal fines or imperfections, and little to no heat generation.
