A material reduction machine includes a prime mover driving a cutting mechanism. An infeed portion engages a piece of material to feed it forward to the cutting mechanism. A sensor senses a machine load parameter via the cutting mechanism and/or prime mover and reports a signal to a controller operatively coupled to the infeed portion to control sequential cutting cycles on the piece of material. The controller utilizes a stored first stop threshold value for stopping a first cutting cycle and continues monitoring the signal as machine load increases momentarily after reaching the first stop threshold. The controller determines and adopts a second stop threshold value based on observation of the machine load parameter indicative of maximum load during the continued monitoring following attainment of the first stop threshold, and further being based on a stored correction factor. The second stop threshold value is used for a second cutting cycle.

A chipping device that has a chipper framework and a rotor having a plurality of spaced apart replaceable knives, teeth or strikers mounted on a periphery of the rotor and which cooperate with at least one anvil for comminuting desired limbs, branches or trunks of trees into chips having a desired size. A combustion engine supplies rotational drive to at least the rotor. A hydraulic power source for supplying power to hydraulic components of the chipping device and controlling operation thereof. Both the engine and the hydraulic power source being solely and entirely supported by the chipper framework so as to move along with the suspendable chipping device.

A process for producing an optimized granular material producing a granular material in a granulating mixer having a container and a stirrer tool, and comminuting at least a part of the granular material in a granular material conditioner which has two elements which move relative to each other, and granular material is passed through a gap between the two elements.

Processing of baled material includes a bale opening stage, a separation stage, and a decortication stage. The bale opener features a conveyor moving incoming bales toward a toothed extractor with an array of teeth driven on a revolutionary path moving upwardly past the adjacent end of the conveyor to rake through the bale and extract material therefrom. The conveyor tilts upward reduce a working angle between the conveyor and the toothed extractor to urge the shrinking bale toward the moving teeth. A separation stage features multiple sets of vertically stacked, counter-rotating rollers with different characteristics from one set to the next. A decorticator has an external container, an internal drum rotatably supported therein, and an array of teeth on the drum. Driven rotation of the internal drum spins the fibrous stalks around the internal drum and impacts the fibrous stalks against surrounding interior wall surfaces of the external container.

An apparatus and a method for composting organic material. The apparatus comprises a container (10) having a first end (11), a second end (12) in the form of a hemispherical wall, and a jacket (13) extending between said ends. The container operates in an inclined (al) position. A transporting and mixing device (30) in the container transports organic material in a transport direction (L1) from the first to the second end and simultaneously mixes the organic material. The transporting and mixing device directs the organic material towards the hemispheric wall, whereby the organic material is first directed upwards along the hemispheric wall and then turned back against the transport direction. A fluffing device (40) in the container comprises a shaft (41) being perpendicular to the transport direction (L1) and cutter blades (50) extending outwards from the shaft (41).

In one embodiment, a hydroseeder has an integrated bale grinder. The hydroseeder includes a tank, an agitator, a plurality of grinding flights, and a basket. The tank includes an opening and is configured to hold a material slurry. The agitator is positioned below the opening and is configured to agitate the material slurry. The plurality of grinding flights extends from the agitator and is configured to grind a material bale as it is introduced into the tank. The basket extends from the opening of the tank and is configured to direct the material bale toward the plurality of grinding flights.

A mincer includes a housing, a hinged door, a handle, a cam, an axle, and a plurality of circular blades mounted on the axle. Rotation of the handle or knob with respect to the housing causes rotation of the cam with respect to the housing, which in turn causes the axle and the blades mounted thereon to travel radially outward or inward with respect to the housing to extend or retract the blades out of or into the housing. The mincer can be operated to extend the blades for operation and to retract the blades for storage. The door can be closed for operation and opened for cleaning of the mincer.

A blade head for granulating strands of material comprises a blade carrier and at least one granulating blade fastened thereto. The respective granulating blade is fastened to a positioning component which bears against the blade carrier for the rough positioning of the granulating blade. For fine positioning purposes, at least one adjusting element bears against the respective granulating blade. The blade head permits simple, user-friendly and precise assembly and setting of the respective granulating blade.
