  • Patent number: 8695903
    Abstract: A system for processing slag material from a steelmaking process includes reducing the average particle size of slag from a steelmaking process into finer particle size material by directing the slag against a surface at a velocity sufficient to cause the slag to break into smaller pieces, and separating the finer particle size material into at least an iron rich product and a silicate rich product based on the differences between these products in at least one or more properties including magnetic susceptibility, particle size, weight or specific gravity. Directing the slag against a surface to reduce the average slag particle size can better separate the dissimilar materials in the slag from each other, and result in less dust generation and less energy consumption compared to grinding the slag material.

    Abstract: A particle reduction system and method is disclosed having an air stream accelerator, a feeder assembly, a variable speed wheel lock operably associated with the feeder assembly for releasing raw material into a conveying air stream created by the positive displacement pump, and a particle conditioning assembly. The raw material is carried by the conveying air stream through the particle conditioning assembly, where particle of the material are collided with each other for the purpose of reducing the size of the particles. In some embodiments, a non-thermal drying system can be used to extract moisture from the raw material. The moisture/solids separation occurs, in large part, due to a head-on collision of two conveying air streams. The collision creates a large squeezing force, much higher than a centrifuge or filter. This impact squeezing acts to squeeze the moisture out of the raw material.

The pulverizer mill (12) performs a first round of identification and separation by dividing the reclaimed carbonaceous material into small agglomerates and large agglomerates. The pulverizer mill (12) further fractionates the large agglomerates to form more small agglomerates. The small agglomerates are then moved to a classifier (14) that performs a second round of identification and separation. The classifier (14) separates the small agglomerates into coarse agglomerates and fine agglomerates.

    Abstract: A scrap material recycling apparatus includes a feeder, a shredder and a separator, the feeder and the shredder mutually coupled, and the shredder and separator mutually coupled. The feeder includes a means for compressing a quantity of scrap material and means for advancing the scrap material to the shredder. The shredder includes a rotor having a plurality of cutting means, the rotor mechanically rotated to reduce the scrap material. The separator separates the reduced scrap material by fractional composition. The recycling apparatus may be part of a system further incorporating additional components, such as conveyors and/or dust extraction devices. The recycling apparatus may be further adapted so as to be a transportable system, thereby allowing such system to be relocated at or near scrap material stockpile locations.

  • Patent number: 7984865
    Abstract: A method and apparatus for processing animal byproduct materials is disclosed. In some embodiments, the apparatus includes a grinder for grinding the byproduct materials; a mixer for mixing the ground byproduct materials with an oil absorbing material and a backmix material; and a dryer for drying the mixed materials. In some embodiments, the apparatus also includes a cyclone for separating an air stream from the dried materials. The dried materials are transported to one or more presses for pressing the dried materials, thereby reducing oil content. The one or more presses includes a first opening for delivering pressed oil to a centrifuge and a second opening for sending the pressed materials to a screener. A portion of the screened material is sent back to the mixer (and/or the grinder) and the balance of the screened material are sent to storage as a finished product.

  • Patent number: 7975940
    Abstract: A system for reducing the particle size of a pozzolan includes a thermal fracture system and a defracturing apparatus. The system is highly efficient at drying and heating a natural pozzolan having a natural distribution of particle sizes. The system can create a reduced-size pozzolanic material with a desired particle size and particle morphology. The system for reducing the particle size of a pozzolan includes a thermal fracture system for heating and thermally fracturing the pozzolan and a defracturing apparatus that agitates the thermally fractured pozzolan to break the thermally fractured pozzolan apart.

  • Patent number: 7931220
    Abstract: A clean dry white glass powder useful as a substitute for Portland cement in concrete, in paints, and for other known uses for glass powder produced conventionally can be produced from unsorted post-consumer waste glass, including a substantial fraction of non-glass items, by employing glass pulverizing equipment to reduce waste glass to small fragments, allowing removal of trash, employing a multistep washing process to clean the glass fragments, in the preferred embodiment using aggregate cleaning equipment, drying the fragments, preferably using fluidized bed techniques, and grinding the glass to a desired particle size, preferably using a ball mill, in combination with an air classification step to produce a bright white glass powder of uniform particle size.

  • Patent number: 7891590
    Abstract: Method for reusing bituminous products (11), in particular bitumen containing roofing materials and membranes, wherein the bitumen containing products are placed in a second hopper (9), where a particulate material having a grain size between 5 mm and 35 mm is placed in a first hopper (5), and that in the bottom of the second hopper, conveyor means (10) urges the bituminous material into a mixing chamber (8), and that inside said mixing chamber a milling and/or crushing wheel (14) is arranged, which wheel engages and crushes/mills the material transported from the second hopper in an engagement zone, and at the same position as the wheel engages the bituminous material, the particulate material by means of a first conveyor (7) is fed into the engagement zone, and that the wheel's action will fragment the materials and at the same time mix the fragmented bituminous materials and the particulate materials, and transport the material past a sieve (15), where material having a particle size smaller than the sieve

  • Patent number: 7854406
    Abstract: An air separator is provided with a rotor positioned above three concentric vessels. The rotor and a plurality of entry ports segregate comminuted material into the three vessels. An exit port from each vessel directs the separated comminuted material for further comminution processes, such as to a ball mill or a roll press, or for use as a final product.

  • Patent number: 7828236
    Abstract: A grinding mill grinds grains or similar foodstuffs, while the concept of the invention could also be applied to other feed materials. The grain is fed at a controlled rate to an impeller chamber, ground by the impeller until a small enough size to fit through a sieve, and separated into a sample cyclone stream and a bulk or waste cyclone stream. Each cyclone includes a central air return duct which channels air back to the grain feeder chamber and then into the impeller chamber. By having the air from grinding recirculated back to the grinder after separation, the grain grinding process is cleaner and results in less moisture loss.

  • Patent number: 7802740
    Abstract: A shredding machine having a plastics loading section and a paper loading section. The two loading sections feed material to be shred into a single cutting section. The plastics loading section may include a ram that urges loaded materials into the cutting section for shredding. The cutting section may include a plurality of cutters mounted on a pair of adjacent cutting shafts. The cutters on one shaft are intermeshed with the cutters on the other shaft. The cutting shafts rotate in opposite directions to cut apart materials fed into the cutting head. The teeth of one cutter are offset from the those of adjacent cutters to evenly distribute the forces generating during cutting. The machine may include a material collection/filtration system having a vacuum that creates a negative pressure in the cabinet and a filtration bag for collecting the shredded material. The filtration system may also include a HEPA filter for collecting airborne particles that are not captured in the filtration bag.
