APPLICATION OF PULVERIZED COAL IN MINING INDUSTRY ...
Pulverized coal is composed of different size and irregular shaped of diamond powder. particle diameter generally is range of 0 – 1000um, mostly 20 – 50um particles; density of pulverized coal is low and pulverized coal new grinding bulk density had approximately (0.45 – 0.5) t/m3, after a time the bulk density of (0.8 – 0.9) t/m3; pulverized coal has mobility.
