    Lets calculate/select/pick a new ball for your SAG mill. Now, lets suppose you have a SAG Mill and Ball Mill that are not drawing full kW Power. The SAG Mill has a “small” circulation load of oversize given be the 3/8″ trommel screen and the 1/2″ x 1 1/4″ discharge grates. The load of 4″ balls in this SAG is “good” but un-measured. SAG Ball consumption is “average” at 400 g

  • Modelling SAG milling power and specific energy

    Comminution, particularly milling, is on average the largest consumer of energy in mining. Actual comminution circuits consist in most of the cases in coarse crushing, SAG milling, pebble crushing and secondary ball milling. In these circuits the SAG mill is the largest energy consumer.

  • What is the difference between a SAG mill and ball mill?

    A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. [6] [7] The largest SAG mill is 42′ (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. [8] A SAG mill with a 44′ (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed. [9]
