The Lagrangian discrete phase simulations and analysis have been carried out for three dimentional geometric model of the coal pulverizer
the movement regularity of coal particles with different particle size being obtained at different rotation speed of the classifier
and then the influence of particle size concerning coal in the pulverizer and throat size of the rotary classifier upon the separation efficiency has been studied.Through enlarging the throat size
the separation efficiency and coal fineness distribution have been improved without increasing the pressure loss in coal pulverizer.
