  • Assessing the benefits of automatic grinding control using PST technology for true on-line particle size measurement
    Patent number: 11260399
    Abstract: A mineral extraction system features at least one hydrocyclone, each having input piping, underflow piping, a cyclone portion and overflow piping; a particle size measurement device arranged on some part of the at least one hydrocyclone and configured to sense particles flowing in a process medium, and providing signaling containing information about the size of the particles in the process medium; and a controller having a signal processor configured to receive the signaling, and determine control signaling to control some part of the mineral extraction system, based upon the signaling received.
    Type: Grant

  • OBJECTIVE FUNCTION FOR AUTOMATIC CONTROL OF A MINERAL ORE GRINDING CIRCUIT BASED ON MULTIPLE SIZE MEASUREMENTS OF THE FINAL GROUND PRODUCT SIZE FROM HYDROCYCLONE CLASSIFIER OVERFLOW STREAMS
    Publication number: 20210023570
    Abstract: A mineral processing system featuring a controller having a signal processor or processing module configured to: receive signaling containing information about a relationship between multiple particle size measurements of different measured particles having different measured particle sizes flowing in a hydrocyclone classifier overflow stream sensed by at least one particle size measurement device arranged on a hydrocyclone classifier overflow pipe of at least one hydrocyclone in a hydrocyclone battery, and about a floatable fraction that defines a particle size range of different floatable particle sizes of different floatable particles that can be recovered by the at least one hydrocyclone in the hydrocyclone battery; and determine corresponding signaling containing information to control a ground product size of ore having ground particles provided to the at least one hydrocyclone in the hydrocyclone battery, based upon the signaling received.
