  • Pulverizing technique and rolling mill for use therein
    Patent number: 5180113
    Abstract: Vibration in the operation of a rolling mill is minimized by mixing unground raw material with partially ground material being recirculated in such a manner that the material fed to the bowl of the mill is homogeneously mixed whereby variations in the frictional forces within the bowl will be reduced. If necessary, the moisture content of the mixture being fed into the mill bowl may be increased to ensure that the grinding operation is performed efficiently.
