A portable debris shredder for shredding lawn debris for easier stockpiling or disposal.

A electronic grinder includes a main body removably attached to a grinding and dispensing chamber. The top of the main body is sealed by an upper cab and the bottom of the chamber is sealed by an openable lower cap. The main chamber includes a motor connected to a magnetically attached removable blade. The blade extends into the chamber when the grinder is assembled. When the lower cap is closed, the blade grinds material placed in the chamber. When the lower cap is opened, the blade functions as a fan to dispense ground material out of the chamber. The grinder also includes a display, an electronic scale, and an accessory cigarette lighter.

A culinary leaf shredder apparatus for cutting leaves such as collard greens includes a receptacle and a housing with a housing cavity. The housing has a feed slot and a dispense slot extending through to the housing cavity. A pair of rotor axles is coupled to within the housing cavity and a pair of rotors is coupled to the rotor axles. A plurality of shredder tangs is coupled to the pair of rotors. The plurality of shredder tangs intertwine beneath the feed slot to shred leaves and pass them through the dispense slot. A drive mechanism is coupled to the pair of rotors. A motor is coupled within the housing cavity and is in operational communication with the drive mechanism. A control panel is coupled to the housing and is in operational communication with the motor and a power source.

A powered mulcher is configured for attachment to a vehicle. The mulcher includes a frame assembly and a drum assembly contained within the frame assembly. The drum assembly includes a substantially cylindrical drum and a cutting array mounted to the drum. The cutting array includes a plurality of flights connected to the drum and a plurality of cutters attached to each of the plurality of flights. The plurality of flights are configured to push processed plant debris away from the ends and middle of the drum.

A system for processing plant materials is described. The plant materials have at least plant stalks, and the plant stalks comprise at least bast fibers. The system has a crusher module for disrupting the plant materials without breaking or damaging the bast fibers thereof, thereby obtaining disrupted plant stalks and a first plant-remainder; a decorticator module coupled to the crusher module for separating the disrupted plant stalks into bast fibers as a first product and a second plant-remainder; and a screening module coupled to the decorticator module for separating at least the second plant-remainder to microfibers and hurds as a second and a third product, respectively.

A mobile chipper shredder includes a removable fin plate positioned within the rotor chamber. The removable fin plate includes a main body that has an arcuate shape and a plurality of fins that extend toward a rotor assembly from the main body. The fins are spaced on the main body so as to not interfere with paths of travel of a plurality free-swinging shredding hammers of the rotor assembly within the rotor chamber. The plurality of fins radially overlap at least one path of travel of the plurality of free-swinging shredding hammers.

A material reducing machine includes a rotary reducing drum that is rotatable about an axis of rotation and defines a reducing boundary that extends at least partially around the axis of rotation. The material reducing machine includes an infeed conveyor for transporting material to a front portion of the rotary reducing drum and defines a conveyor plane. The material reducing machine includes a mill box at least partially surrounding the rotary reducing drum and including a mill box lid mounted generally above the rotary reducing drum. The mill box lid has an inlet edge positioned above a rear portion of the rotary reducing drum and an outlet edge positioned above the front portion of the rotary reducing drum. The mill box includes an infeed opening that is configured to receive material from a feed table and has an upper opening defined by the outlet edge of the mill box lid.

A multi-region twin-shaft cutting system for chopping material. The cutting system includes two shafts which are arranged in parallel and are driven in an opposed manner, each shaft is surrounded by a roll body. The system additionally includes a multiplicity of supporting elements, each supporting element is fitted radially around the roll body. The system further includes a multiplicity of severing elements which are of disc- and/or plate-like design and are each fitted symmetrically or asymmetrically tangentially to the circumferential region of the supporting elements.

A shredding device is provided comprising two shredding shafts arranged parallel to each other with shredding elements arranged thereon, wherein the shredding shafts are preferably rotatable mechanically synchronized to each other. A shaft-side coupling element is connected to a respective first end of the shredding shafts. The shredding device includes a housing with a housing-side coupling element is provided that can be coupled to the shaft-side coupling element. The shredding device includes a displacement device enabling displacement of the shredding shafts for decoupling and coupling the shaft-side coupling element from or to the housing-side coupling element.

The comminution device (100) according to the invention comprises a feed opening (10) for feeding material to be comminuted, a comminution shaft (20) for comminuting the material fed to the device, and a cutting chamber (30), arranged between the feed opening (10) and the comminution shaft (20) and delimited by a cutting chamber wall (40a, 40b). The comminution device according to the invention is characterized in that the cutting chamber wall (40a) can be pivoted. The invention also relates to a corresponding method.
