Here, the torturous path causes the fine particles to be separated from the coarse particles. The fine particles exit the mill thru the fuel pipes and the coarse particles are returned to the bowl thru the inner cone for further size reduction. At the coal pulverizer exit, the coal-air stream is distributed directly to the coal pipes.
