Materials with different grinding properties to be ground simultaneously, e.g. in 'the manufacture of cement, are fed from storage bins 3 via a conveyer 2 to a tube mill I the output from which is delivered to a conveyer 4 which delivers it to a separator 5 the ground end product from which is discharged whilst the rejects are delivered through a pipe 7 to a screening classifier 8 which delivers the screened material through a pipe 9 to the tube mill whilst the coarse grain is fed through a pipe 10 to a beater mill 11 the output of which is combined with that of the tube mill, the beater mill being regulated by means of a regulator 13 in dependence upon the end product 6 of the separator. The separator may, alternatively, be arranged after the classifier. |
