coal magnetic separator

The Magnex Process is a dry beneficiation process which involves: (1) crushing, (2) heating, (3) carbonyl treatment, and (4) magnetic separation. The coal is crushed to nominally minus 4-mesh prior to treatment. The crushed coal is heated to approximately 170/sup 0/C (338/sup 0/F) then subjected to

    Magnetic Separator - an overview | ScienceDirect Topics

    Commercial magnetic separators are continuous-process machines, and separation is carried out on a moving stream of particles passing into and through the magnetic field. Close control of the speed of passage of the particles through the field is essential, which typically rules out

    Dry coal preparation without the use of water • STEINERT

    For traditional plant we offer the STEINERT WDS wet drum magnetic separators, which are optimised for the recovery of magnetite and ferrosilicon from the heavy media of the sink/float separators. In this way, traditional coal washing can be performed economically, through the recovery of the heavy media

    US5873313A - Magnetic separator and pulverized coal

    Pulverized coal X is ejected together with air Y from a header (11) through piping (12) and a valve (13) to a baffle plate (14). Pulverized coal is made to fall into the inner duct (3). Paramagnetic materials such as ash are attracted by magnetic force to the tube and are then collected by a collection tube (26)

    Magnetic separation of coal fly ash from Bulgarian power

    Oct 01, 2020 Fly ash from three coal-burning power plants in Bulgaria: 'Maritza 3', 'Republika' and 'Rousse East' were subjected to wet low-intensity magnetic separation. The tests were performed at different combinations of magnetic field intensity, flow velocity and diameter of

    Fine Coal Desulfurization by Magnetic Separation and the

    Dec 31, 2014 Pyrite in fine coal was heated selectively by microwave energy to strengthen its magnetism in this study. Then, the inorganic sulfur in fine coal (−0.5 mm) was removed using a 2 T strong magnetic roller magnetic separator. The migrating regulation of organic sulfur-containing groups and harmful elements was analyzed by employing a microwave energy-intensive process

    Oct 22, 2013 Magnetic Separator in Coal Conveyor (Alarm / Tripping) ? Dear Sirs, In our power plant, metal detectors are provided in the conveyors. The metal detector gives an alarm when metal pieces are detected and signals to trip the conveyor drive is not provided. The contractor says that alarm is sufficient and if tripping of the conveyor is provided, then it will stop all the upstream conveyors

    Aug 20, 2019 A wet-drum magnetic separator is then used to recover the magnetite from the slurry that flows from the drain-and-rinse screens. While magnetite losses are often blamed on the magnetic separator, they could be occurring in another area. Magnetite could be lost in multiple stages of the coal beneficiation process
