New Progress in Dry Coal
Bed is used for sorting 5O ~ 6rtllTl coarse coal, so the fluidized bed so you can explore the control 400rtllTl ensure sufficient separation of space to meet the needs sorting,mulberry bags uk, and easy to control the bubble generation grew up,fake oakley sunglasses, to ensure that bed layer of uniform density stability. To meet China's top ten large open pit coal mine (300 ~ 50mm) exclusive gangue separation, need to study the deep-bed-type air dense medium fluidized bed. Clearly,true religion outlet, to meet the needs of a large lump sorting. Bed depth should be controlled at 1200rtllTl so. We focused on the deep air dense medium fluidized bed-type gas distribution principle,radii shoes sale, increase the quality of properties and a large lump separation dynamics. Fluidized bed to achieve a uniform density,Salvatore Ferragamo outlet, the bubbles small and mergers and less purpose in the laboratory a model of machine to achieve a large lump of effective separation. ? value of 0.02 (3) <1lnrll micro-pulverized triboelectrostatic technology triboelectrostatic the basic principles are: electric properties with different surface materials transported by air entrainment, and the friction between particles and particle friction between the device material collision, so that the different particles to bring the opposite polarity charge. Into high-voltage electrostatic field, the polarity of the charge materials with different polarity of the electrode to the opposite direction, so as to achieve separation. Laboratory test results showed that: triboelectrostatic limit is less than 320 mesh can be divided into election (O.043ram) micro-pulverized coal. Obviously, in such a fine level of material in the mineral has been largely dissociated, triboelectrostatic of micro-pulverized coal ash has a good selection of desulfurization down the role. Receive ash <2% of low-ash coal, the current pilot system has passed technical appraisal. (4) three double-density layer of the proct air dense medium fluidized bed coal technology to simplify processes, optimize proct structure, there is need to study up to a machine three different ash procts out of the double-density layer of air dense medium fluidized bed. This requires sorting room in the same bed in the formation of double-density fluidized bed layer. The results show that: in the appropriate process, operating conditions and structural parameters, can form double-density fluidized bed layer. And effective sorting, light proct separation with separation density of 15O ~ 1.54g/cm ~, E is O. O6 ~ O. O9; re-proct separation with separation density of 1.84 ~ 1.90g, Eo is 009 ~ 0.11. Through this series of studies, expected in the near future to achieve full-grain-efficient coal dry separation, coal instry and promote the further development of clean coal technology.
