Grinding plant for the comminution of grinding stock as well as a method for the comminution of the grinding stock

摘要

The invention relates to a grinding unit 10 for the comminution of the grinding stock, comprising at least a grinding device 12, 16 and a with the at least one grinding device 12, 16 in which the sifting device 14 for screening of the mill base with a static classifier and a dynamic classifier, wherein the static sifter is arranged in such a way that it at least partially surrounds the dynamic classifier, wherein the sifting device 14 at least one coarse material outlet 24 for the outlet of a coarse particle fraction of coarse material which has, at least one material or tailings outlet 26 for the outlet of an average particle size fraction grits and having at least a finished material outlet 28 for the outlet of a fine grain fraction which has finished material, wherein the grinding plant a control method according to the - / regulating device for controlling / regulating at least a portion of the grinding stock current to the at least one grinding device 12, 16 has.The present invention also relates to a process for the comminution of the grinding stock, comprising at least the steps of comminuting of the mill base is in at least one of the grinding device 12, 16, sifting, of the mill base in a sifting device 14 in the coarse material, oversize material and fine material, wherein the sifting device 14 a static classifier and a dynamic classifier, wherein the static sifter is arranged in such a way that it at least partially surrounds the dynamic classifier, and wherein the grinding stock current to the at least one grinding device 12, 16 by means of a control method according to the - / regulating device is regulated / controlled.
