also the pulverised coal in mill and the raw coal fed into the mill contribute to the variation of the pressure. From the working principle of a Tube-Ball mill [7], it is known that there is actually no rotation mechanism like paddles spinning inside of the mill. The mill outlet pressure is a compromised aerodynamic result among the mill inlet
