This study analyzes the exergy efficiency of comminution using a laboratory sized dry ball mill and a copper mineral ore from central Chile. In this research, we develop a minimum work index from uniaxial compression tests results on the ore fitted to Morrell's comminution energy equation using Hukki's constant mineral parameter.

Mills usually have motors in the following range: SAG mill motor: 7,435 kW or an HPGR circuit with motors: Ball mill 1 (4,015 kW) and Ball mill 2 (4,152 kW) for a porphyry copper- molybdenum mine. Comparing mill operations for both open pit mining to underground mining, where the metal is separated from rock ore containing the metal mined, both ...
the SAG mill and ball mill was 8658 kW, which caused partial over-grinding. From experience in processing plants outside of China, the power rating of the ball mill should be higher than that of the SAG mill [5]. The pebble crusher had an over-powered configuration. The installed power draw of 630 kW

AG/SAG mill feed, trommel screen undersize product (-5.00 +0.00 mm), ball mill discharge and cyclone feed, overflow and underflow have been conducted in order to characterize the particle size distribution in the products and to carry out mass balancing of grinding circuits.
The inventor, Mr. Lawrence Nordell developed the concept of the CAHM as a by-product of studying SAG mills using DEM (Nordell and Potapov, 2015).It was noticed that 80% of the comminution occurs in a small area (referred to as the 'sweet spot'), inside the SAG mill, where 10 times higher shear work is observed than in the other areas of the mill (see Fig. 1).
Not surprisingly, comminution is a huge expense. After all, we're crushing rocks here. Interestingly enough, the crushing isn't always the most expensive part of crushing. Crushing machinery, particularly the SAG mill is massive, and much of the expense of …
