  • Patent number: 10076857
    Abstract: A system and method for processing a supply of post-consumer scrap linear low density or low density polyethylene film into near-virgin quality blown film product. The method includes tearing the supply of film in a shredder, wherein the surface area of the film is exposed, including delaminating the film. The torn supply of film is washed in a water bath including a surfactant. The film is agitated in the bath containing the surfactant wherein contaminants on the film are removed from the film. The washed film is ground into smaller pieces and additional washing of the ground film in a rotating friction washer and a sink float tank occurs wherein additional contaminants are removed from the film. The ground film is then dried and compacted without addition of water into granulated objects of near-virgin quality blown film product.

  • Patent number: 9963308
    Abstract: Embodiments of the present disclosure a system for capturing proppant dust particles when positioned at a fracking operation site including a proppant delivery assembly to receive one or more containers having proppant stored therein. The system dispenses the proppant from the one or more containers and delivers the proppant to other fracking operation equipment. Moreover, the system includes a dust collection assembly positioned proximate and associated with the proppant delivery assembly to capture dust particles released by movement and settling of the proppant when being dispensed and delivered by the proppant delivery assembly. The dust collection assembly is positioned to direct an air flow in a flow path overlying the dust particles to capture the dust particles and move the dust particles away from the proppant thereby reducing risk of dust exposure to fracking operation site personnel.

    Abstract: The invention relates to a method for grinding mill material and to a roller mill and is suited in particular to a finest grinding of relatively hard and dry materials, for example cement clinker and granulated blast furnace slag and also for relatively large roller mills. In order to avoid mill vibrations due to over-grinding of the mill material and to reduce the specific work requirement as well as increasing the throughput a fine material nozzle is arranged after each grinding roller, from which fine material nozzle an air jet with defined impulse is directed from above onto a fine material concentration zone. The fine material concentration zone is formed directly after the grinding zone of each grinding roller and is virtually free of supplied material to be ground and accumulated on a retention rim region. The fine material blown outwards and upwards is fed to a rising conveying air flow and subsequent classifying process.

  • Patent number: 8783588
    Abstract: A bran finishing process in grain milling employs a milling machine in which bran that contains some endosperm, including aleurone, is fed into an annular milling chamber defined on an inner side by an eccentric cylindrical rotor and on an outer side by a frame assembly that includes perforated screens and abrasive surfaces. Longitudinal lobes protrude radially from the rotor. The lobes compress the bran as they rotate, while the lesser diameter of the rotor between lobes allows the bran to decompress, causing bran particles to rub together for detaching endosperm from the bran by friction forces. Bran particles also rub against the abrasive surfaces for scraping endosperm off the bran. Air flows through the milling chamber and carries the endosperm through the perforated screens, while the bran particles are discharged without passing through the screens.

  • Patent number: 8757523
    Abstract: Processing waste materials to recover valuable metals, such as copper, from the materials. The disclosed systems and methods employ processes that further refine the waste materials to concentrate the metallic material after the waste materials are initially processed. Processes include employing air separation and screening. Processes also include employing a dynamic sensor and a vacuum pressure separator to separate metals from other materials. A central processing facility may process metal concentrate from multiple concentration facilities.

  • Publication number: 20140166787
    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.

  • Patent number: 8714361
    Abstract: Materials in battery and electrochemical cells are separated in a form suitable for recycling by employing froth flotation techniques. Bulk materials, such as casings, are removed from converted battery scrap and the resultant pulp is subjected to froth flotation. Froth flotation agents, including frothers, collectors and/or depressants, are used to manipulate the hydrophilic and hydrophobic nature of the materials in the scrap. Hydrophobic materials are entrained in the air bubbles of the froth and float out of the froth flotation vessel while those that are hydrophilic remain in the vessel, thereby separating battery grid materials without resort to pyrometallurgical, energy intensive or other environmentally undesirable processes.

  • Patent number: 8684287
    Abstract: A coffee grinder includes a machine base, in which a crushing unit, a separating unit, and a grinding unit are provided. The machine base has an inlet and an outlet, and the crushing unit is under the inlet to crush coffee beans into parchments and beans. The separating unit has a rotary member and a collection container that the rotary member provides an air flow to send the parchments to the collection container. The grinding unit is between the crushing unit and the outlet to grind the beans from the separating unit and send the ground beans to the outlet. The present invention crush the coffee beans to separate the parchments and the beans, and the parchments are removed by the separating unit. Next, the beans will be ground.

  • Patent number: 8590818
    Abstract: An apparatus wherein the gas enters from an opening 4 located in a part of a compaction chamber 3 and is dragged through a granulator 5, a fractioning device 12, a special cyclone 11 and a filter system 8A to a suction fan, which creates a gas stream. In such apparatus the bulk to be compacted 1, the fine particles to be compacted again and the compacted bulk have the same flow direction than the carrier gas. Due to its complete or partial impermeability, the structure of the apparatus makes also possible the use of a gas different from normal air. This is important when the bulk is sensible to oxygen.

  • Patent number: 8567702
    Abstract: A method for processing a supply of post consumer scrap linear low density or low density polyethylene film into near-virgin quality blown film product. The method includes tearing the supply of film in a shredder, wherein the surface area of the film is exposed, including delaminating the film. The torn supply of film is washed in a water bath including a surfactant. The film is agitated in the bath containing the surfactant wherein contaminants on the film are removed from the film. The washed film is ground into smaller pieces and additional washing of the ground film in a rotating friction washer occurs wherein additional contaminants are removed from the film. The ground film is then dried and compacted without addition of water into granulated objects of near-virgin quality blown film product.
