20080314802 | Mobile metal reclamation soil processing apparatus and related methods - Mobile metal scrap recovery apparatuses and methods of operating them to remove scrap metal from scrap metal-contaminated soil are disclosed. In a preferred embodiment, a mobile metal scrap recovery apparatus comprises first and second wheeled components, each of which is road transportable. The first wheeled component comprises a unit for screening the metal scrap-contaminated soil into at least a coarser fraction and a finer fraction. The second wheeled component comprises a magnet separator, an eddy current separator, and a manual picking station. Methods for conducting the business of scrap metal recovery are also disclosed. Such business methods involve the use of a mobile metal scrap recovery apparatus to remove scrap metal from scrap metal-contaminated soil. | 12-25-2008 |
20110017644 | Method and System for Separating and Recovering Like-Type Materials from an Electronic Waste System - Recovering like-type materials from an electronic waste stream. The recovered materials can include, without limitation, ferrous and non-ferrous metals and plastics. Also, printed circuit board materials and precious metals can be recovered. Distinct technologies are combined to achieve the separation of the unique materials. | 01-27-2011 |
20110094943 | MAGNETIC SEPARATOR - There are provided devices, systems and processes to treat slurries that include magnetic and nonmagnetic particles suspended in water in such a fashion as to separate certain valuable elements and/or minerals from less valuable minerals or elements. A high intensity magnetic separator includes at least one large rotatable turntable that defines at least one circular channel therethrough in which a matrix material is positioned. The turntable is configured to rotate in a generally horizontal plane about a generally vertical virtual axis, causing the at least one circular channel to rotate through a plurality of intermittent magnetic and nonmagnetic zones generated by a plurality of permanent magnet members. A treatment slurry is directed into the channel or channels in one or more of the magnetic zones as the turntable rotates. A tailings fraction passes through the channel or channels in a generally downward direction in the magnetic zones and is collected in tailings launders. Magnetic particles are attracted to the matrix material in the magnetic zones and remain in the channel until it passes into an adjacent nonmagnetic zone, where the magnetic particles are washed form the channel into concentrate launders. | 04-28-2011 |
20110240528 | Metal Recycling Separator and Method of Use Thereof - A metal recycling separator comprising a shredder having a sloped shaking table disposed entirely within the shredder. The shredder shreds materials into ferrous and non-ferrous materials and the sloped shaking table disperses the ferrous and non-ferrous materials onto a first conveyor belt. Non-ferrous materials are separated from ferrous materials by conveying such through two drum electromagnets, wherein the ferrous material and the remaining non-ferrous materials are transferred to a water receptacle. The water receptacle is filled with water, wherein a part of the remaining non-ferrous materials float out of the water receptacle, and the remaining ferrous materials sink to the bottom of the water receptacle. The ferrous materials and residual non-ferrous materials are then conveyed out of the water receptacle and onto two conveyor belts and a third drum electromagnet. Ferrous material is removed from the two conveyor belts and is also removed via the third drum electromagnet. | 10-06-2011 |
20120325726 | IRON ORE SEPARATION DEVICE - Slurries of magnetic and nonmagnetic particles in water are treated in a high intensity magnetic separator including at least one turntable that defines at least one circular channel therethrough in which a matrix material is positioned. Rotation of the turntable in a generally horizontal plane about a generally vertical virtual axis causes the circular channel(s) to rotate through a plurality of magnetic and nonmagnetic zones generated by magnet members. Treatment slurry is directed into the channel(s) in one or more of the magnetic zones as the turntable rotates. A tailings fraction passing through the channel(s) in a generally downward direction in the magnetic zones is collected in tailings launders. Magnetic particles attracted to the matrix material in the magnetic zones remain in the channel(s) until they pass into an adjacent nonmagnetic zone, where the magnetic particles are washed from the channel(s) into concentrate launders. | 12-27-2012 |
20130043167 | VERTICAL RING MAGNETIC SEPARATOR FOR DE-IRONING OF PULVERIZED COAL ASH AND METHOD USING THE SAME - A vertical ring magnetic separator for de-ironing of coal ash comprises a rotating ring ( | 02-21-2013 |
20130240415 | METHOD AND SYSTEM FOR PROCESSING SLAG MATERIAL - A method and system is used to process slag material to yield by-products including a finished iron rich product and a finished low iron fines product. The by-products may include a finished high iron product and a finished medium iron product. The method and system include size classifying the material into a plurality of sized groups prior to using magnetic separation to separate at least one of the sized groups into two portions having differing magnetic susceptibilities. The method and system may include more than one phase of size classifying the material into a plurality of sized groups and using magnetic separation to separate at least one of the sized groups into portions, where the average size of the material remaining after one phase is reduced prior to the subsequent phase. | 09-19-2013 |
20140209516 | MAGNETIC SEPARATOR WITH DYNAMIC BAFFLE SYSTEM - A dynamic baffle system for a magnetic separator includes a containment barrier secured to a frame and positioned between a rotary screen drum and a magnetic drum. The dynamic baffle system further includes a baffle configured to block an opening of the containment barrier. The baffle is movable between an open position in which media mixture is capable of flowing from the containment barrier to the magnetic drum and a closed position in which the media mixture is prohibited from flowing from the containment barrier to the magnetic drum and configured to evenly build up on the containment barrier. The dynamic baffle system further includes a sensor and a controller coupled to the sensor and the baffle to control the amount of media mixture flowing from the rotary screen drum to the magnetic drum. | 07-31-2014 |
20150114888 | WASTE FOUNDRY SAND TO FRAC SAND PROCESS - Foundries utilize quartz foundry sand and generate waste foundry sand as a by-product. Frac sand exists with other components within the waste foundry sand. A configuration of machinery processing a flow of quartz waste foundry sand into frac sand includes a screening device separating the flow and providing the frac sand. | 04-30-2015 |
20150298140 | Foreign Object Barrier Device for Bulk Material Conveying Ducts - A device for conveying a fine bulk material including a housing with an opening therethrough for conducting such material; at least one conduit spanning such opening having a set of spaced openings along the length thereof, and connectable to a fluid pressure source; a member of porous material overlying a portion of such conduit, including end portions secured to such conduit and an intermediate portion spaced from such conduit, providing a chamber intercommunicating the openings in such conduit and the pores of such overlying member; and a magnetic bar disposed in such conduit provides a passageway between such fluid pressure source and such conduit openings. | 10-22-2015 |
