Modelling: Transfer size limits - SAGMILLING.COM

For example, the SAG mill may have 10 MW of power draw available and the two ball mills each of 7.5 MW of power draw available for a total of ratio of 10:15 (1:1.5). The software uses the particular power model (Bond/Barratt, Morrell Mi, etc.) to determine what is the transfer size where the ratio of E SAG to E ball matches the ratio of mill power (1:1.5 in this example).

Selection of Comminution Circuits for Improved Efficiency · PDF file

Typically, a SAG mill based circuit (P80 of 106 to 150 um) has media costs of around A$1/t. Providing the ore is amenable, the use of primary autogenous milling can reduce this cost by 40%. Autogenous milling is typically practiced in association with . pebble crushing to improve circuit power efficiency. The pebble flow provides an ideal source of media for secondary milling and a number of ...
