A low speed low power shredder for biomass material a single drum or two spaced rotary drums supported in a housing having a cylindrical wall with a plurality of outward shear members spaced longitudinally and radially of the cylindrical wall so as to pass a cooperating element in a shearing action. The shear members form ends of a support plate extending diametrically through the wall so as to provide structural support. In the two drum system, a top grate member is mounted in the feed throat and a bottom grate member is provided underneath the plane of closest approach. Each of these grate members provide shearing actions with the shear members. Additionally, a composting machine is arranged to be fed by a shredder, and thus includes an input conveyor supported at a position coaxial with a rotary vessel of the composter and a tubular support member which defines one location at which the rotary vessel is supported in its rotation about its axis.

A blender system includes a container having a rotatable blade assembly therein, a lid covering an open end of the container, and a base with a motorized unit. When the container is coupled with the base, the motorized unit is adapted to drive rotation of the rotatable blade assembly. The lid includes a hinged actuator lever adapted to actuate the motorized unit. A detent extends from the hinged actuator lever and passes through a series of apertures and presses against a slidable actuator shaft disposed in the container and maintained in its position by a spring force, thereby depressing a switch for the motorized unit. A rotatable blade system includes cutting blade(s) and crushing blade(s). The crushing blade extends longitudinally outwardly from a hub. When the hub rotates in a first direction or second direction opposite the first direction, a face of the crushing blade is leading or trailing, respectively.

A processing machine includes an infeed system, a processing tool assembly, and a discharge system. The processing machine includes a rotor defining an outer surface, with the processing tool assembly at least partially mounted to the rotor. The processing tool assembly includes a tool holder mounted to the outer surface of the rotor with the tool holder having a pocket structure defining an inner cavity. The processing tool assembly also includes a tool body having a tool retention portion and a tooth holding portion with the tool retention portion disposed within the inner cavity of the pocket structure. The processing tool assembly also includes a processing tool mounted to the tooth holding portion, and a retaining plate secured to the tool holder and abutting a portion of the tool body such that the tool retention portion of the tool body is retained within the pocket structure.

The invention relates to a machine blade comprising a cutting body and a fastening portion for fastening the cutting machine blade to a rotary drive. The cutting body has: a central area defined by at least two lateral surfaces that extend approximately parallel to one another; and edge regions adjacent thereto, the thickness of the cutting body in each edge region decreasing from the central area towards an associated edge of the cutting body. Furthermore, the cutting body has at least one blade comprising a cutting edge at an edge of the cutting body that is in front with respect to a direction of rotation during operation. The machine blade is designed to be rotationally driven about an axis of rotation during operation. A radius of the machine blade extends from the axis of rotation to an outer edge of the machine blade.
