### Energy Consumption in Mining Comminution

There is a dearth of information about energy consumption specific to individual mines. One study [6], which is a collaboration that compares seven mine mill/concentrator operations: four gold and three iron ore mines. The average energy needed for seven mines is summarized in figure 2, where the energy requirement is broken down into six components: crushing, grinding, processing, tailings,SPECIFIC COMMINUTION ENERGY - SMC Testing,the specific energy of the crushing section, the HPGR section and the tumbling mill section separately. Hence, for example, in the case of an SABC circuit the total specific energy of the entire comminution circuit will be predicted plus the individual specific energies of the primary crusher, pebble crusher and combined SAG/Ball mill stages. The model was originally developed using 3 data,(PDF) Predicting the overall specific energy requirement,,Download full-text PDF, work index than the crusher (ie the ball mill is less energy efficient . than a crusher and has to input more energy to do the same amount of size reduction). Hence from,

### MODELING THE SPECIFIC GRINDING ENERGY AND BALL-MILL

MODELING THE SPECIFIC GRINDING ENERGY AND BALL-MILL SCALEUP K. G. Tsakalakis & G.A.

To address this fact new models are developed in this work able to pre- dict power or speciﬁc energy consumption, including the usual design variables, but adding a variable that represents the feed size distribution. Operational data from 4 grinding circuits corresponding to 3 Chilean copper concentration plants are used and the % 600 +100 ( 152 +25 mm) is,Comparing ball and vertical mills performance: An,,seen, the vertical mill consistently presented lower net specific energy consumption than the ball mills which operate on the same circuit. The averages were 11.3, 11.7 and 6.5 kWh/t respectively for ball mill 01, ball mill 02 and vertical mill. Figure 5 – Net specific energy consumption of regrinding circuit. Nevertheless its impossible to guarantee, industrially, that all the mills are fed,

that the additional specific energy for ball milling is the same as the difference in specific energy between open and closed crushing to reach the nominated ball mill feed size. This assumes that a crusher would provide this energy. However, in this situation the ball mill has to supply this energy and it has a different (higher) work index than the crusher (ie the ball mill is less energy,Predicting the overall specific energy requirement of,,01/05/2009· Tumbling mill specific energy correction for size distribution, (higher) work index than the crusher (i.e., the ball mill is less energy efficient than a crusher and has to input more energy to do the same amount of size reduction). Hence from Eq. , to crush to the ball mill circuit feed size (x 2) in open circuit requires specific energy equivalent to: (9) W c = 1.19 ∗ M ic 4 x 2 f (x 2,Ball Mill Design/Power Calculation,The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed,
