A treatment system for plastic material includes a feeding device, a treatment unit, and a plasticizing device arranged downstream thereof. The treatment unit has a comminuting device and a conveying device which are received in a housing. An outlet opening is arranged in an end region of a conveying section of the conveying device. The plasticizing device has an extruder screw which is received in an extruder housing. The extruder housing is equipped with a filling opening which is arranged so as to directly adjoin the outlet opening arranged in the housing. In the region of the outlet opening, the conveying device has a circulating direction which runs in the opposite direction of the conveying direction of the extruder screw.

Shredding device for shredding material comprising a housing: a rotor and one or more counter blades which are arranged in the housing such that they interact for shredding the material; a pusher element that is movable such that it pushes the material to be shredded in the direction towards the rotor and the counter blades; a hopper for feeding the material which is arranged movable on the housing between a first and a second position, where, in its first position, the material may be fed to the rotor and the counter blades, and in its second position, the rotor and the counter blades are freely accessible from the exterior of the shredding device.

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.

Size-reduction machines, feed units, and methods capable of producing reduced-size products from a variety of solid and semisolid materials. Such machines have an impeller that rotates on an approximately horizontal axis and an opening at an axial end of the impeller. A feed unit includes a feed hopper for feeding products to an interior of the impeller through the opening of the machine, and a slicing knife is mounted to the impeller and radially protrudes across the opening of the machine to slice products into segments as they enter the interior of the impeller.

A food grinder comprises a base housing a motor, a throat portion coupled to the base, a receiving tube coupled to the throat, a feeding tray coupled to an upper end of the receiving tube, a selectively rotatable auger selectively insertable into and removable from the throat portion, and a storage tray sized and shaped to be selectively insertable into and removable from the feeding tray. The storage tray comprises a main body having a plurality of depressions formed in a top surface thereof. Each depression is sized and shaped to hold one or more accessories for use with the food grinder.

A meat grinder includes: a housing; a drive unit mounted in the housing, the drive unit including a motor; a screw conveyor comprising a barrel fixed relative to the housing, and an auger located within the barrel and operatively connected with the motor; a hollow feed chute having upper and lower ends, the lower end mounted on and configured to feed into the barrel; and a feed tray mounted on the upper end of the feed chute, the feed tray including an opening in communication with the upper end of the feed chute. The feed chute includes an inlet section of a first inner diameter that includes the upper end, a feed section of a second inner diameter that includes the lower end, the second diameter being less than the first diameter, and a funneled section between the inlet section and the feed section.

A paper shredder having shredder cover and a motor coupled to shredder blades includes a shredder throat in proximity to shredder blades. The shredder throat has a moveable blade, and a fixed blade. A shredder jam grip has a projection in communication with a power switch plunger. When the shredder is in the NORMAL position, a throat gap is in its normal position and the projection positions the plunger to power to the motor. When the shredder is in the JAM CLEAR position, the throat gap is in its wide position and the projection positions the plunger to remove power from the motor.

A waste processing system includes a cutting system and a feed system, wherein the improvement relates to a safety and control system which comprises a side mount actuator having at least two operable positions, wherein the actuator is in communication with the waste processing system and is adapted to selectively control the operation thereof.
