Aerodynamic Principle In Coal Mill

Aerodynamic Of Coal Grinding Mill. 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.
