turning coal mill classifier

Numerical and experimental analysis of pulverized coal
The coarse particles first collide with the radial surface of the classifier and lose some kinetic energy If the coarse particles lose enough energy due to the collision then the large and heavy coal particles move downward and turn back towards the mill for further pulverization from the return outlet of the pulverizer 6 .

Investigation of wear pattern in a complex coal pulveriser
The mill classifier allows the fine enough particles to pass on to the external burners while the coarse particles are returned to the mill rotating table for further grinding and size reduction Large quantity of airflow rate is required to transport the pulverized coal from the mill table upwards through the classifier and to the burners.
