Abstract: A system for shearing bulk material includes a shearing cartridge with an input port and an output port. A first plurality of rotatable blades are disposed about a first shaft, Each of the first plurality of rotatable blades includes a center aperture such that the first shaft extends through the center apertures of the first plurality of rotatable blades to selectively rotate each of the first plurality of rotatable blades simultaneously. A second plurality of rotatable blades is opposingly offset from the first plurality of rotatable blades. Each of the second plurality of rotatable blades includes a center aperture such that the second shaft extends through the center apertures of the second plurality of rotatable blades to selectively rotate each of the second plurality of rotatable blades in a direction opposite the first plurality of rotatable blades to shear and reduce the bulk material.
