The coal is a very important raw material in the steel industry [6]. It is extracted in the form of solids of con-siderable size and as such form may not generally be burned, sintered or gasifi ed. So it must be properly com-minuted. Grinding of coal generally uses two types of crush-ers, namely, the drum crushers and the hammer crush-ers.

This evaluation was carried out by monitoring the signal intensity of the four Se isotopes (77 Se, 78 Se, 80 Se and 82 Se) in a 10 times diluted digested coal sample at different H 2 flow rates. A blank solution prepared in 5% HNO 3 was also measured in the same way, in order to find the conditions providing the best signal to noise (S/N) ratio.
