A crushing apparatus includes a first rotary shaft member, a second rotary shaft member, a plurality of first rotary cutters, a plurality of second rotary cutters, a plurality of first spacers, and a plurality of second spacers, the first rotary cutters and the first spacers being alternately disposed in a first axis direction, the second rotary cutters and the second spacers being alternately disposed in the first axis direction, the first rotary cutters and the second rotary cutters each forming a tearing blade that protrudes in a direction perpendicular to the first axis direction, a portion of each of the first rotary cutters and a portion of each of the second rotary cutters overlapping when viewed from the first axis direction, and a gap being provided between the first rotary cutter and the second rotary cutter in the first axis direction.

A method of operating an apparatus for the comminution of a botanical feedstock wherein a blade that is positioned above a screen and the blade is rotated at a rate of rotation, wherein the trailing portion of the blade generates turbulence that induces upward movement of cut and partially cut feedstock from the upper surface of the screen to a plane of rotation of the cutting edge of the blade.

An apparatus for the comminution of a botanical feedstock includes a vessel, a screen positioned in the vessel above a first feedstock outlet and spaced from the top of the vessel, and a blade rotatably mounted above and generally parallel to the screen. The blade has a leading side, a trailing side, and a radial blade length. At least a portion of the leading side has a cutting edge and at least a portion of the trailing side has a downwardly extending trailing portion. The downwardly extending trailing portion has a lower edge having a plurality of discontinuities along a radial length of the trailing portion. The cutting edge is spaced from the upper surface of the screen by a first distance and a lowermost portion of the lower edge is spaced from the upper surface of the screen by a second distance.
