  • Why can SKT jigging be applied to thermal coal

    Jigging coal has many advantages such as large processing capacity, low investment and operation cost, high separation precision, etc Therefore, the jig process should be preferred in the fieldCurrent socalled dry coal preparation technologies, such as pneumatic tables and wind jigging, provide low separation efficiencies and tend to generate significant dust pollution One potentially effective approach to the cleaner utilization of coal is air dense medium fluidized bed (ADMFB) dry coal cleaning technology, which provides high efficiencies together with enhanced separation and lowCharacterization of bubble behaviors in a dense phaseDry jigging of coal has long been a proven technique for upgrading coal, the modern air jig, with its improved efficiency and operating systems simply extended the range of applicationsEffect of fluidizing characteristics on upgrading of

    Furthermore, the SX sample coal magnetic susceptibility rapidly decreased, almost an order of magnitude lower than that of the raw coal susceptibility This is mostly likely due to the high amount of pyrrhotite in the sample SX coal's fine magnetic susceptibility was in the order of 10 − 9, whereas the total sulfur of SX coal is 366% The sulfur of pyrite is 215%, whereas the pyrite to pyrrhotiteThe jigging studies of a synthetic binary mixture of quartz and coal were carried out The variables studied were the particle size, bed thickness, number of strokes per minute, and water levelOptimization of A Jigging Process Using StatisticalSimilarly, jigging is also used in a variety of applications: x Separation of mineral contaminants from coal using an air jig (Oder and Weinstein 2008) x Recovering ferroalloys [Ferrochrome (FeCr), Ferromanganese (FeMn), and Ferrovanadium (FeV)]Michigan Technological University Digital Commons
