Modelling SAG milling power and specific energy

2017-12-14  Comminution, especially milling, is the most important opera-tion in mineral processing, both for its relevance to the down-stream processes as well as for the high costs associated with the energy consumption. Comminution is generally the single largest consumer of energy on a mine site, accounting for an average of a 53% (CEEC the future, 2012).

A Review of Advanced Ball Mill Modelling

Nevertheless, it is worth mentioning that the increase in computing power in recent years has enticed researchers to include both grinding media and powder in some simulations of small ball mills, which has been particularly useful to understand the collision frequencies and energies involved in media-particle contacts (Cleary and Morrison, 2011; Wang et al., 2012; Capece et al., 2014).

Comminution processes: Basics and application to energy

2015-3-2  Different possibilities to define energy efficiency: 1. Specific energy of mill compared to new created surface energy → not meaningful, efficiency much smaller that 1% 2. Specific energy of mill compared to minimum specific energy requirement in so-called element tests. However, here at least two possibilities exist:

USING THE SMC TEST® TO PREDICT COMMINUTION

2020-3-24  Specific Energy Determination for Comminution Circuits The total specific energy (W T) to reduce in size primary crusher product to final product is given by: W T = W a +W b +W c +W h +W s (3) where . W. a = specific energy to grind coarser particles in tumbling mills . W. b = specific energy to grind finer particles in tumbling mills . W. c

2015-2-1  Although gold mill throughput in terms of % design capacity was higher than base metal mills in 2012, a steeper curve could result in greater savings for the gold processing facilities. Conversely, a flat curve would yield a lower difference between part-load and full-load specific energy consumption, thus the savings would also be less.
