  • Patent number: 7237735
    Abstract: A method and device to protect a grinding mill, at startup from a gravity-balanced condition thereof, used for grinding material therein by rotating the drum so that the material adheres to the drum inner surface and rises therewith over a cascading angle from a startup position at the gravity-balanced condition prior to detach by gravity from the inner surface and tumble into a cascading flow. The method is used for protecting the grinding mill from damages potentially resulting from the material agglomerating into a generally solidified lumped volume that could adhere to the inner surface and rotate therewith more than the cascading angle to a fall angle wherein the lumped volume may detach from the inner surface and impact an impact position within the drum.
    Type: Grant

  • Patent number: 7017841
    Abstract: A method and device to protect a grinding mill used for grinding material therein by rotating the drum so that the material adheres to the drum inner surface and rises therewith over a cascading angle from a gravity-balanced condition prior to detach by gravity from the inner surface and tumble into a cascading flow. The method is used for protecting the grinding mill from damages potentially resulting from the material agglomerating into a generally solidified lumped volume that could adhere to the inner surface and rotate with the latter more than the cascading angle to a fail angle wherein the lumped volume may detach from the drum inner surface and impact an impact position within the drum.

  • Publication number: 20030052205
    Abstract: An angle-based method and device to protect a grinding mill used for grinding material therein by rotating the drum so that the material adheres to the drum inner surface and rises therewith over a cascading angle from a gravity-balanced condition prior to detach by gravity from the inner surface and tumble into a cascading flow. The method is used for protecting the grinding mill from damages potentially resulting from the material agglomerating into a generally solidified lumped volume that could adhere to the inner surface and rotate with the latter more than the cascading angle to a fall angle wherein the lumped volume may detach from the drum inner surface and impact an impact position within the drum.
