    Semi-Autogenous Grinding Circuit Reduces Capital Costs

    There are two Koppers 15.5 foot by 22 foot secondary pebble mills, driven with 1500 h.p. synchronous motors. Each grinding stage operates in closed circuit with cyclones, and the primary cyclone overflow is the feed to the secondary mills. The circulating load in the primary stage can be controlled by adjusting the cyclone apexes."

    Better separation: CycloStack CycloWash | FL

    The CycloWash, located in the lower/apex section of the hydrocyclone, injects water into the cyclone, and the injection water displaces the fines-laden water in the partially thickened underflow pulp. The result, essentially, is a second stage of classification taking place, where the displaced water with fines joins the normal cyclone overflow.
