A shredder comprising a rotor and stationary structure. The rotor includes a shaft provided with a series of grooves and split blades mounted within said grooves, this by attachment means penetrating the shaft. The fixed structure forms an anvil or reaction structure having a series of independently removable, supported, upright transverse support blocks having hardened metal segments provided with upper cutting or shearing edges. The anvil structure includes an elongate cutter bar forming, with the cutting edges of said segments, a U-shape groove through which the individual blades pass. All of the hardened-metal, and preferably tempered steel cutting segments are completely supported by the fixed support structure and are usually independently and individually replaceable as may be needed through the operation of the machine. Ramp-providing rib structures are provided and are likewise split construction for easy removal from the interior hopper area of the shredder.

An apparatus for reducing extra large vehicle tires to particles or to prepare them for recapping comprises a tire holder assembly, made up of a set of dual jacks, in combination with a rotary cutter blade assembly made up of a side-by-side series of discs carrying cutter blades of chisel type. The set of dual jacks are preferably carried by an arbor having opposite shaft ends adapted to matingly interconnect with corresponding ends of a motivating shaft for quick and easy interchange of one size tire holder assembly for another size. When the tire is to be recapped, arcuate attachments are secured to members of the tire holder assembly that contact a tire bead so as to preserve the circumferential integrity of such bead during cutting, and the cutter blade assembly is replaced by wire buffing brushes following removal of the tread portion of the tire by cutting. An optional feature of the invention is the freezing of the tire prior to cutting, so that steel reinforcing materials as well as the elastomeric material of the tire can be easily reduced to particles.

Reduction structure including a revolving rotor and stationary structure. The revolving rotor is notched to provide a series of cutter sockets that individually receive cutters, preferably hardened steel cutters. The cutters are arranged in their sockets such that a majority of the length thereof is disposed within each socket; thereby, bolt attachment means may be reduced in number and can conceivably be one in number per cutter. The ends of the shaft are preferably turned down for bearing support and coupling to adjacent prime mover structure. The hopper, within which the rotor as above-described is mounted, preferably includes an anti-rotation member in the form of an elongate bar having one or more declining flanges, these flanges serving to preclude counter-rotation of any element such as logs as may be introduced into such hopper. For reduction such as shearing in connection with automobile and truck tires, the clearances around the individual cutters as the same pass through notches within the stationary cutter bar employed should be reduced to not more than 1/8th of the cutter width; by this restriction the cords in tires are sharply cut and do not string out from cut segments so as to foul materials-handling machinery, screens, and so forth, as may subsequently be used.

A shredder structure, components, and sub-combinations thereof, useful for shearing, shredding, and/or chopping a variety of materials such as municipal and industrial solid waste products, vehicle tires, and other materials desired to be comminuted. The hopper of the structure is preferably hinged to provide easy access to the made-up shaft. The shaft carries a series of rotating bladeholders keyed to the shaft and provided with radial protrusions and contiguous slots accommodating fitted-blade placement. The rotating bladeholders are spaced apart by spacers which serve not only to mutually space the rotating bladeholders, but also to support the sides of the rotating blades so as to form with the bladeholder slot pockets or seats for such blades. Particular support structure is used for the stationary blade employed, with which the individual rotating blades on each bladeholder co-act.

An apparatus for pyrolyzing shredded tires including an oven having a discharge opening and a tote having a discharge snout corresponding to the opening, the tote being placed in the oven with the snout inserted into the opening, radiant heating tubes are provided in the oven in close proximity to the top and bottom of the tote to heat the shredded tires, the tote having an inclined top for directing gaseous vapors produced on heating the tires toward the snout, the gaseous vapors are drawn through a discharge duct assembly and condenser by a fan located at the exhaust from the condenser.

A waste mangler system, optionally provided with classification means, for processing garbage, municipal waste, and the like whereby to mangle or break up compacted garbage and other materials, break open bags and bales, and otherwise treat the refuse for a flailing-type reduction. The machine is vertically oriented and includes a rotor having rapidly revolving cross-arms, mounted to a central shaft, which are provided with rigid impact blades and flail elements. The impact blades include rearwardly tapered leading edges so that debris may slide outwardly thereon under the action of centrifugal force to approach the area of reduction proximate the flail elements used. The material descending through the drum of the machinery is deposited down to suitable conveyer means that may be coupled to air classification or other means for material separation and further processing.

202 97

A process and apparatus for recovering the material components of rubber tires, the process including the steps of shredding the rubber tires to a size capable of being transported, heating the shredded rubber pieces in an inert atmosphere to a temperature sufficient to vaporize the heat recoverable components of the tires, condensing the vaporizable components to liquify the oil and ammonia present, collecting the uncondensed gas, and recovering the carbon residue and metal remaining after cooling. The apparatus including a hot air oven having a plurality of hot air conduits defining a primary heating zone and a top wall configuration defining a gas collection zone and a tote bin formed by a closed container having an opening at one end and a top wall configuration conforming to the top wall of the oven.

A shredding apparatus including a housing or hopper and a shredding assembly positioned within the housing or hopper. The shredding assembly including a cutter bar assembly and a rotary blade assembly. Each of the assemblies including a number of identical cutter blades which are interchangeable with each other and are individually reversible. The cutter bar assembly also including a cutter bar positioned in abutting engagement with one end of each of the cutter blades mounted on the cutter bar assembly. The cutter bar including cutting edges on each side so it can be reversed with respect to the cutter blades. The cutter blades on the rotary cutter bar assembly are arranged to shear waste material at a downwardly and outwardly inclined angle so that the cutter blade acts to draw or pull waste material into the shredder assembly. The hopper or housing being provided with an easy access door on the front wall which can be pivoted outwardly from the hopper.
