Abstract: True zero-clearance cutting on a commercial scale is provided via a cutting area including a sacrifice material that is relatively softer than the cutter. One example is a cutting system which is capable of cutting a material such as, for example, tape or paper, into a fiber or powder. Destruction of the material is further enhanced by advantageous strategic patterning of cutting edges on a rotary cutter, and further by secondary shredding features. For example, on the same axis as the rotary cutter, may be disposed, one on each end, rotating secondary shredders that receive material that has been cut by the rotary cutter as well as material that has escaped cutting by the rotary cutter. A variety of materials, of different thicknesses and types, may be reduced to a dust or powder-size.

Abstract: As-mined oil sand is crushed to −5 inch by a sequentially arranged pair of double roll crushers. The crushed oil sand is fed into a hopper feeding a jet pump. Water or recycled slurry is fed under pressure as motive fluid to the jet pump. The motive fluid jet(s) produced internally by the jet pump are operative to fluidize the oil sand and the components of the slurry mix turbulently in the jet pump's tubular mixer. It is found that the slurry issuing from the jet pump is aerated and largely free of lumps.

Abstract: A rotating claw drum for shredding discarded material (such as used carpet) is created from flat circular plates that are stacked tightly together on a driveshaft or drum, to create an impermeable drum face that prevents particulates from entering and fouling the internal mechanisms. Each flat plate is provided with at least one claw-holding slot in its outer rim; 6 to 12 slots preferably should be provided in each plate. Locking means (such as a locking bar that will pass through aligned locking notches in the slots and claws) will lock the claws in place while the drum is in use. After the drum has been stopped, a locking bar can be removed, to release a damaged claw from its slot so it can be replaced, without having to disturb any other claws.

Abstract: A shredding apparatus includes a rotor having rows of tines projecting generally radially outwardly therefrom, and also a housing surrounding the rotor having rows of tines projecting generally radially inwardly therefrom. The rotor tines and stator tines have staggered positions, with one or more of the rotor tines passing between adjacent stator tines. Material inserted into an inlet at the top of the housing is caught by the rotor tines and pulled past the first row of stator tines. That first row has fewer tines than does each row of tines on the rotor, whereas the final row has the same number of tines as each row on the rotor. The opposing faces of the tines on the rotor and stator are flat, with a small clearance between passing tines, of typically about 1/8 of an inch. The passing flat faces on the tines are at a slight angle to each other, the outer ends of rotor tines passing stator tines ahead of the inner ends in a scissors-like fashion.

Abstract: An apparatus for preparing plant material, such as sugar cane, comminutes the material for further processing, for example, by cane mills or a diffuser. An upfront cutter (2) and a shredder (8) are immediately adjoining each other at the end of an adjustable speed conveyor (1). A material guide housing forms with its guide channel sections an inverted V-shape. One guide channel section reaches upwardly and extends over the discharge gap (6a) of the upfront cutter. Another guide channel section reaches downwardly to the shredder. An intermediate guide channel section interconnects the upwardly and downwardly reaching sections to form a closed guide channel construction. An upper channel wall portion remote from the upfront cutter and from the shredder forms an impact and deflection baffle (11c) for the precomminuted material ejected by the upfront cutter for feeding the material to the shredder. The apparatus is compact and assures a uniform material feed to the shredder.

Abstract: Sanitary articles formed of cellulose flock and non-flock carriers or covers are shredded by rotating entrainers, which are arranged in an enclosed housing. The cellulose flock thus separated is removed from the housing under suction through a sieve which only allow the cellulose flock through. The removal is effected before the covers have been shredded to such an extent that they pass through the sieve. The shredded cover material is then removed separately.

Abstract: The invention relates to a cutting mill for the comminution of runners, injection moulding parts, blown moulding parts and so forth in operation of a synthetic material processing machine. Waste or reject parts becoming available should, if possible, be led back again to the process cycle of the machine after comminution to granulated size for use as a regenerate. For this purpose one makes use of a cutting mill having a cylindrical driven rotor mounted in a housing, over the periphery of which rotor a plurality of adjacently positioned cutting element groups are arranged, which cooperate with at least one stationary blade provided in the housing, wherein a sieve for filtering of the comminuted material extends over a part of the boundary of the rotor.

Abstract: An improved milling process, wherein the material to be crushed is processed within a circular milling path under the action of at least one roller rolling along said path. The material is fed evenly distributed around the circumference of the milling path and enters it with a predetermined initial speed transversely to the extension of the path such that each piece to be crushed is subjected at least once to the action of one of the rollers. Under the action of an air current which is guided across the milling path pulverized material below a given grain size is immediately removed from the milling path, thereby avoiding the build-up of a thick and energy consuming layer on the milling path such that the milling forces are limited to the breaking forces for crushing the pieces fed into the milling path.

Abstract: Continuous scrap edge trimmings are fed from a sheet metal slitter into a scrap chopper incorporating a rotor shaft supporting axially spaced and circumferentially spaced elongated straight cutting bars each having a plurality of selectable straight cutting edges. Each rotary cutting bar revolves past a stationary straight cutting bar also having a plurality of selectable straight cutting edges, and each cutting edge is positioned at a compound angle relative to planes including the axis of the rotor to produce scissor-like shearing of each strip. Each stationary cutting bar is positioned adjacent a spring biased anvil and is supported with the anvil for remote adjustment relative to the path of the corresponding cutting bars on the rotor. Each edge trimming is fed into the cutting bars by a corresponding pair of feed rollers one of which is spring biased and the other of which is independently driven by a corresponding motor.

Abstract: A device for the destruction of microfilm and similar data carriers with microimage impressions which is designed to shred the data carriers by means of a rotating shredding cutter in the form of a plain milling cutter whose teeth move past a transversely extending stationary cutting edge. A strip feeding unit advances the data carrier strip past this cutting edge along a guide plate, said unit including a driven endless conveying member which forms a conveying gap with the guide plate. A second stationary cutting edge forms a second cutting point behind the first cutting point. The strip feeding unit is self-contained and movable against a spring bias in relation to the main frame and its guide plate, so that a safety switch, responding to such movement, stops the device when too many data carriers are fed into the device simultaneously.

Abstract: The apparatus features a conveying means with rakes and other blade members for coarse crushing the chips. The conveying means is in the form of a chain conveyor contained in a trough. The members for coarse crushing of the chips consist of inverted L-shaped grapples, the leading edges of which have a curvature, and of blades, the cutting edges of which face the leading edges of the grapples and are provided with a curvature having a radius which is about equal to the radius of the curvature of the leading edge of each grapple. The blades are fitted to the inside surface of the trough, in at least two rows, above a zone traversed by the chain conveyor, so that the grapples pass between the rows of blades. The inverted L-shaped grapples are suitably attached to links of the chain.
