Abstract:
An improved apparatus for cutting scrap tires is disclosed wherein compressed scrap tires are cut. A scrap tire is compressed, then fed into a plurality of rotary disc cutters axially spaced along a shaft and rotated against a stationary anvil. In the preferred embodiment, cutting tools are vertically mounted on the rotary disc cutters, whose outer circumference is recessed in a concave arc starting at the top of the cutting tool and ending at that portion of the cutting tool closest to the center. The cutting tools are off-set along successive rotary disc cutters rather than placed in a line parallel to the shaft. Anvil tools having at least one cutting edge are mounted on the stationary anvil for ease in maintaining cutting edges opposite the rotating cutting tools. Cleaner bars facilitate the removal of cut scrap tires from the rotary disc cutters and their subsequent collection.
Abstract:
Waste such as combustible trash and prime garbage is mixed with rubber tires and shredded together to produce a compacted and combustible output product which can be used as a fuel or incinerated for further compacting.The process involves interengaging rotary feeder-cutter wheels mounted on counterrotating shafts to pull materials through a feed path while shredding with the aid of shredder blades interspersed between the wheels. Feeding, mixing and conveying techniques through one or more shredder stages provide for attainment of high speed feed rates and handling of some degree solid debris such as steel belts in tires.
Abstract:
A secondary shredder can include a rotor assembly that employs a modular rotor design. Each rotor of the rotor assembly can include a number of blades that are symmetrical around a horizontal and a vertical axis. Each rotor can include a number of radial extensions forming gaps into which the blades insert. The blades can be secured within the gaps by wedges that apply an inward force against the blades when the wedges are secured into the gaps. The radial extensions and blades can include keyways into which keys insert to prevent the blades from escaping the gaps. The secondary shredder may also include a stationary knife assembly that includes multiple stationary knives that are positioned on the same side of the rotor assembly.
Abstract:
A chopping-grinding mill for used objects and other waste materials includes a base, on which a disc-shaped vertical-axis rotor (2) is rotatably mounted, the rotor (2) having a plurality of cutting blades (5, 6) fixed to its upper surface. A disc-shaped coaxial stator (3) is associated with the rotor (2) and carries a plurality of cutting blades (II, 12) fixed to its lower surface. The stator (3) is fixed at an adjustable distance above the rotor (2), which together define a grinding chamber. Primary cutting blades (5, II) extend from the centre to the periphery of the rotor (2) and stator (3) and secondary cutting blades (6, 12) extend only in correspondence of a peripheral crown of the rotor (2) and of the stator (3), while a feeding window (10) of the material to be ground is provided in the stator (3), in the area inside to the peripheral crown.
Abstract:
The present invention is Micro-erosion Recovery System for separating recyclable tire materials (rubber, steel and fiber) and complying with quality standards governing the use of recovered tire materials. It is also a highly efficient apparatus and system for producing large amounts of high quality crumb rubber and steel. The system is controlled by selecting a micro erosion water jet nozzle with a specific cross-sectional area of the inlet and continually taking measurements of the inlet pressure until ideal mesh size of crumb rubber is met. Using the inlet pressure and cross-sectional area of the inlet, the remaining variables are able to be calculated by using an equation known in the art.
Abstract:
A process for producing a rubber powder from a vulcanized rubber material by the steps of: a) feeding a grinding device with the vulcanized rubber material; b) contacting the vulcanized rubber material with at least one liquid coolant; c) introducing at least one grinding aid additive into the grinding device; d) operating the grinding device so as to grind the vulcanized rubber material to form a rubber powder, and e) discharging the rubber powder from the extruder.
Abstract:
A system for preparing recyclable vehicular material may consist of a transportable enclosure including a storage space, at least one opening, and at least a portion of an intake loader, a tire shredder, a fragment conveyor, and a storage floor. The intake loader may receive at least one tire and transport the tire from a loading point to a shredder intake. The tire shredder may receive the tire at the shredder intake and convert the tire into several tire fragments. The fragment conveyor may receive the tire fragments and transport the tire fragments to the storage space. The storage floor may be oriented substantially planar within the storage space and include several moveable sections configured to convey the tire fragments from a first end of the storage space to a second end of the storage space, where the second end of the storage space is located proximate to the opening.

Abstract:
Used tires are chopped up in a punch press which progressively punches out areas of each tire lying flat in the press. The tire fragments are conveyed from the press to a collection container. An elevator mechanism may receive four tires stacked vertically, each used tire therein successively fed into the press by a feed mechanism receiving each tire from the elevator mechanism. An on-site enclosure houses all of the components and a container of collected fragments which is accessed for removal through a door in the enclosure.
