This paper describes a method which allows an analysis of main elements in coal by neutron induced prompt y-ray analysis. An experimental equipment and analysis method were established. C, H, 0. N, S, Cl, Si, Al. Fe, Ca, Ti, and Na in coal samples were determined and the obtained results were in goo
Tests were carried out on six US coals and a crystallized quartz in an instrumented laboratory high-pressure grinding rolls machine equipped with IOO-mm-diameter rolls. As expected, the specific capacity decreased with increased grinding pressure for each material tested. There were significant diff
