Modelling SAG milling power and specific energy. Especific energy modelling SAG mills operation data abstract Comminution, particularly milling, is on average the largest consumer of energy in mining. Actual com-minution circuits consist in most of the cases in coarse crushing, SAG milling, pebble crushing and sec-ondary ball milling.Specific comminution energy of ball mills 01 pdf ME For tumbling mills the specific comminution energy (Wi) relates to the power at the pinion or for gearless drives the motor output. the purposes of this approach it has been assumed that the additional specific energy for ball milling is the same as the difference in specific energy between.

Apr 27, 2020 In conjunction with the Bond ball mill work index, they can be used to accurately predict the overall specific energy requirements of circuits containing AG and SAG mills, ball mills, rod mills, crushers, and high pressure grinding rolls (HPGRs). SMC Testing says. The comminution circuit throughput also increased annual gold production by.

Ball mill circuits operating within the normal range of appli-cation. This guideline does not directly address analysis of crushing plants and fine grinding circuits, but it is a useful reference for such endeavors. Applying power-based analysis techniques requires suf-ficient input information to allow actual specific energy.
