Patents by Inventor Peter Graenicher

Peter Graenicher has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for measuring the fineness or bulk density, apparatus for carrying out the method and control system with such an apparatus
    Patent number: 5407138
    Abstract: The fineness of bulk material, particularly of material to be ground, is determined by means of a flow measurement (DIN 66126) and by using a calibration correlation between medium particle size and permeability of the sample.The medium fineness of a continuous flow of bulk material determined in such a way at predetermined intervals of time may be used for adjusting roll mill parameters. In the same way, it is possible to calculate the bulk density, so that a compacting procedure subsequently to a milling procedure can be adjusted accordingly.
    Type: Grant
    Filed: September 30, 1993
    Date of Patent: April 18, 1995
    Assignee: Buhler AG
