mining closed circuit ball mill

  • Definition of closed

    16-6-2019Definition of closed-circuit grinding A size-reduction process in which the ground material is removed either by screening or by a classifier, the oversize being returned to the grinding unit. Typical examples are a dry pan with screens, dry milling in an air-swept ball mill, and wet milling in a ball mill

  • Circulating load calculation in mineral processing closed

    Wills (1986) demonstrated how complex circuits can be solved by transforming the productive flowchart in a graph, where each node represents a unit operation. The present work shows a low complexity algorithm with high convergence speed for circulating load calculation in mineral processing closed circuits.
