    2018-7-19 · Pebble Crushing. The Bagdad mill, built in 1977, was designed for a mill capacity of 36,300 tpd. An ABC (Autogenous Mill-Ball Mill-Crusher) grinding circuit was chosen. The original mill contained three completely independent grinding circuits,

    Optimizing Performance of SABC Comminution

    The pebble crusher was reduced in size and the pebble bin capacity was increased to allow for a more consistent flow into the pebble crusher. Uncrushed pebbles were returned directly to the SAG mill, bypassing the pebble crusher, to further improve circuit efficiency.

    Optimizing Performance of SABC Comminution

    Accordingly, it was decided that elimination of the pebble crusher in the circuit was not viable. The discharge grates of the SAG mill were identified as a key component in the SABC circuit, and their design is a crucial factor in the mill’s performance [17,18,19,20,21]. The initial design of the grate section caused a serious accumulation of
