Multiphase flow simulation of a simplified coal pulveriser
Description of pulveriser. Coal pulverisers or mills grind coal typically from 10 to 50 mm size coal lumps to provide fine coal dust particles usually less than a micron up to several microns in size (with at least 70% by weight not exceeding 75 μm). These fine coal dust particles are used as a feed to combustion furnaces.

Raw Coal Spillage Or "Pyriting"
Coal dribble or spillage is raw coal that is rejected through the pulverizer's pyrite discharge. This is caused when the velocity across the pulverizer throat is too low to maintain suspension of coal. Air velocities through the pulverizer throat should be 7,000 to 7,500 Fpm when calculated on a free jet basis.
