Method for mechanical processing of brown coal, preferably the fine brown coal

摘要

method of mechanical treatment in vacuum high-pressure lignite, especially silt lignite is that brown coal is subjected to pre crushing to obtain crushed nadawy, representing the input production to processing, especially a carbon brun atnego diameter of grains in the 0 - 1 mm for at least 65% by weight nadawy,after what nadawu0119 he's drying out in the cylinder torpedowym of rozpu0119dzaniu grains nadawy in cylinder powered by air from the bottom, causing movement of nadawy around wall cylinder with speed not lower as 50 m / sec.then change the internal structure of nadawy, introducing nadawu0119 coal chamber ekstrudacyjnej conditions existing in vacuum pressure there for at least 20 bars and subjected to mechanical compression, combined with traffic in posuwistym chamber ekstrud acyjnej during at least 300 seconds, where as a result of compression, translucent grains.their structure is subject to burst, air and space between grains is total reduction, and introduces additional components, so-called. reduktanty, aimed at reducing oxides of sulphur and sulphur binding in przerabianej nadawie coal in the proportion of at least 0,5% of active lime or lime solution, the so-called.milk of lime for every 1% sulphur content in coal nadawie, after which przesuwanu0105 and with the pressed nadawu0119 crowd by wylotnik whose nozzle outer is oval shaped or polygon with diameters from 5 to 500 mm and a length of the outgoing and peletu from 10 to 500 mm.
