  • Model Predictive Control for SAG Milling in Minerals

    Protecting the mill liners from direct impact. Conversely for hard ore, mill speed is increased to input more energy to the process and improve the tumbling action to deliver the required grind. The following variables may be measured in SAG mill circuits and used for control purposes: ? Ore feed rate ? Image analysis (particle size) on.

    A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

    CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The difficulty of stabilizing SAG mill load limits the effectiveness of feedback control approaches. Control is particularly difficult during periods when the feed ore is either unusually hard or fine. There is also a strong tendency to lose control during transient periods when feed ore changes.
