In grinding and flotation processes, the new era of operational efficiency seeks greater productivity and recovery from ore reserves. Implementing a control system for typically less than one million dollars achieves this goal. The mining industry has used primarily expert system, model predictive controller, and fuzzy logic control systems.

Grinding equipment for mineral processing. The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the ...

Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both ends and the product …

Grinding is used to primarily liberate useful minerals and secondarily provide fine ores with a proper particle size for separation. Gaudin [ 9 ] developed a mineral liberation model for breakage, but it considered materials only as cubes of equal volumes in an excessively simplified mineral mosaic relation.

However, the dynamic model of mineral grinding is difficult to establish and too complicated to use in a control design. In this talk, we present a data-driven model-free control method for mineral grinding control with input constraints. The controller is composed of two components: a steady-state internal model and an optimal regulator.
