A wood chipper comprises a frame, an infeed system, a rotatable cutting system, and at least one feed wheel disposed between the infeed system and the cutting system to feed wood material to the cutting system. The wood chipper also includes a winch comprising a winch line having a first end, and a collar disposed adjacent the first end of the winch line. The wood chipper further includes a detector adapted to detect a first and a second position of the winch line, wherein the detector is adapted to allow operation of the at least one feed wheel and prohibit operation of the winch when the first position of the winch line is detected, and to allow operation of the winch and allow operation of the at least one feed wheel in a predefined manner when the second position is detected. The wood chipper further comprises a bypass for operation of the at least one feed wheel.

The invention relates to a comminuting machine (8) with a rotor system, in particular a knife ring flaker, in which the feedstock is conveyed pneumatically in the axial direction into the central region of the rotor (10) and is conveyed in the radial direction to the comminuting tools arranged around the rotor (10) in the manner of a ring. In order to uniformly wear the knives extending in the axial direction in such devices, it is proposed to provide in the central region (14) an insert (15) which is rotatably driven by a motor (22) and which has separate chambers (16, 17) with which the feedstock entering said chambers is dispensed at axially and radially to different regions. This insert (15) can, in particular, be designed as a rotor, which has a plurality of chambers which are especially shaped in the cross-section in the manner of a circular sector.

A truck-mounted cargo box houses a commercial-grade system for blowing loosefill insulation material in bags through a hose, without first removing insulation from the bags. The cargo box and system include bag feeding means, and a chute having an inlet end positioned in an end wall of the cargo box mounted on the truck. Also included is a material processing unit in the form of a wood-chipper style or other industrial and/or commercial grade shredder, for together shredding the bags and the insulation material, without first removing the insulation material from the bags, and conditioning them both, as a composite material, to be fed into a fluid stream through the hose. There is also disclosed a kit for retrofitting a cargo box, and a related method.

There is provided a scrap crushing and carrying apparatus, including: a coarse crusher for crushing scraps; a fine crusher for further crushing the scraps crushed by the coarse crusher; and a carrier for storing the scraps or carrying the scraps to the coarse crusher or the fine crusher. The carrier includes a filter unit provided inside the carrier to collect dust in the carrier.

A crushing mill for crushing fibrous material for a unit for forming absorbent cores in a machine which makes absorbent sanitary articles, including a casing having an infeed opening and an outfeed opening for the fibrous material, a rotor rotatable about its axis of rotation and housed in the casing at an intermediate position between the infeed opening and the outfeed opening. Also provided is an auxiliary opening operatively interposed between the infeed opening and the outfeed opening, with reference to a direction of rotation of the rotor, and adapted to allow feeding a particulate absorbent material into an intermediate zone between the infeed opening and the outfeed opening.

A comminuting machine includes a frame, a comminuting rotor coupled to the frame, and a rotary drive coupled to the rotor. The rotary drive including a controller, a multi-phase motor connected to the controller, a set of contactors disposed between the controller and the multi-phase motor for selectively providing driving motive force to the multi-phase motor, and at least one rheostat disposed between the controller and the multi-phase motor, in parallel with the first set of contactors, for selectively providing a stopping resistance to the multi-phase motor to effect frictionless braking of the comminuting rotor, wherein the controller is configured to operate the set of contactors and the at least one rheostat to single phase lines of the multi-phase motor for providing the stopping resistance.

A pet waste vacuuming collection and disposal apparatus for collecting and disposing of animal feces includes a handle attached to a mulching mechanism that is capable of shredding animal feces into a plurality of crumb particles. The mulching mechanism includes a housing with an exhaust hole providing access to an interior space of the housing. A motor, vacuum blower, and mulching blade are mounted within the housing. A disposable bag may be removably attached to the exhaust hole. A tube extends from the housing opposite the handle. When the motor is activated, the vacuum blower suctions animal feces up through the tube, into the mulching blade, and out of the exhaust hole, where the shredded feces particles are collected in the disposable bag.

A waste processing machine for reducing material and having a docking safety system. A cutting assembly on a frame reduces material. A feed system on the frame directs material toward the cutting assembly. A winch assembly includes a line with a line end for securing material, and a driver on the frame to urge the line end toward the driver. A keeper fixed to the frame secures the line end to the frame. A docking subassembly, spaced from the keeper, is movable between: a docked position with the line tensioned against the subassembly between the driver and the line end secured to the keeper; and an undocked position with the line loosened against the subassembly. A control unit allows operation of the feed system when the subassembly is in the docked position, and at least partially limits operation of the feed system when the subassembly is in the undocked position.

Provided is a pulverizing apparatus (100) including a pulverization chamber (110) provided with a plurality of stationary blades (111) on an inner peripheral surface, a rotary shaft (120) rotatably supported by the pulverization chamber (110), a plurality of rotary plates (130) fixed to the rotary shaft (120) and separated with intervals in the horizontal direction, and having a plurality of a rotary blades (131) on an outer peripheral surface, tip ends of the rotary blades (131) having space of 0.3 to 0.5 mm between tip ends of the stationary blades (111), a paper powder feed port (140) to which paper powder is fed, a rotation driving unit (150) which rotates the rotary shaft (120) so that a peripheral speed of the tip ends of the rotary blades (131) is 19 to 30 m/sec, and a screen (160) arranged inside the pulverization chamber (110) having mesh openings of 130 to 400 m.

An apparatus for slicing food products includes a housing including an inlet, for receiving food products to be sliced and an outlet for discharging the sliced food product. A primary shaft is supported in the housing for rotation about a primary axis. The primary shaft carries a plurality of slicing blades that are rotatable with the primary shaft about the primary axis. A secondary shaft is supported in the housing for rotation about a secondary axis. The secondary shaft carries a plurality of slicing blades that are rotatable with the secondary shaft about the secondary axis. The primary and secondary shafts are positioned in the housing in a spaced and parallel manner so that the slicing blades are arranged in slicing pairs. Each slicing pair includes one slicing blade on the primary shaft and one slicing blade on the secondary shaft. The slicing blades in each slicing pair have peripheral portions that overlap each other. The apparatus further includes at least one biasing member for biasing the overlapping peripheral portions of the slicing blades of each slicing pair against each other.
