Abstract
A bowl mill for pulverizing coal, wherein two bowl surfaces are rotated on the same shaft. The raw crushed coal is pulverized in one of the bowls, and the pulverized coal therefrom is then transported in an air stream to a classifier from where the fines are carried on to the ultimate point of use, and the more coarse particles are discharged into the second bowl for further grinding.
