Development of a Tube-ball Coal Mill Mathematical

2009-7-20  From the working principle of a Tube-Ball mill, 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 pressure, suction pressures generated by the Exhauster Fan A1 A2, mass of raw coal inside of the mill, and mass of pulverized coal inside of the mill. So, the mill
