Extractions of size granding classes in undersize
Abstract
On the basis of averaging of 544 balances of grain-size screening products distribution of the largeness classes extraction coefficients are set in a subsize product at dry and wet preparatory screening of ordinary coal and shallow machine class deslurring. Findings can be used for determination of indexes of the indicated technological operations at the calculations of quality-quantitative and water-slime coal preparations factories charts.
