Modeling of a medium speed coal mill

 · On the basis of the mass balance of coal in the coal mill, the model of coal powder and raw coal in the coal mill are established as Eqs. (6) , (7) , respectively. (6) M c ̇ = W c − K conv M c , (7) M pf ̇ = − W pf + K conv M c , (8) W c = K c N c , where W pf is the amount of coal powder that is blown out of the coal mill per unit time, which is proportional to ∆ P pa and M pf [Eq.
