• Comminution circuits for gold ore processing

     · Pebble crushing. The first consideration when discussing pebble crushing is why there is a need for the unit operation. Secondly, the configuration of the overall pebble circuit merits discussion. Pebble crushing, almost a standard for SAG circuits today, was controversial early in the development of autogenous grinding (AG) SAG milling. This ...

    Pebble Crushing Circuit Design. Aug 11, 2018· The Pebble Crushing Circuit. Once a critical size has been established in a primary mill, an efficient means of extracting it, crushing it and returning the crushed product to the primary mill has to be designed. In some plants, crushed pebbles are advanced in part to secondary grinding.

  • Dynamic Modeling and Simulation of SAG Mill Circuits with Pebble Crushing

    The power draw of a big SAG mill can be up to 20 MW, while its pebble crusher power draw is usually only 300 to 1000 kW. It needs to be mentioned that the recycling load occupies around 20% of the total SAG mill throughput and up to 50% in an AG mill circuit (data based on the author's observations from FL customer plants).
