### Ball Mill Size and Motor Power Requirements

Nov 12 2013· ball mill power . dear experts. we have a ball mill in combi mode for cement grinding . roller press before the ball mill. the supplier has given 28 grinding media filling with shaft power 2270 kw only. ball mill size is 4.4 11 m. grinding media size is max 30mm . it is a monochamber mill designed to grind the roller press product. The combination of these effects means that the speed for which peak power consumption occurs is predominantly determined by the shear strength of the charge material and the fill level. This demonstrates the sensitivity of mill behaviour to the charge characteristics and the critical importance of various assumptions used in DEM modelling.

### Modelling SAG milling power and specific energy

the mill power and the efﬁciency of the mill operation (Van Nierop and Moys 2001). If a SAG mill has been designed with a conventional power or speciﬁc energy model which do not con-sider the projected feed size distribution it is likely that this mill will reach the expected power consumption 16.5 ft ball mills with an efﬁ ciency of 0.88. A study carried out by the author in 2004 on the Worsley Alumina Rod/Ball Circuit Line No 1 showed efﬁ ciencies of 1.27 for the rod mill and 0.67 for the ball mill. The particle size distributions reported are shown in Figure 1. It follows that the

### Optimization of mill performance by using

Mill power Usually plant operators use mill power readings as an indicator of ball filling degree and often try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between ball mill specific power consumption The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to draw this power is calculated from known tables the

### Optimization of mill performance by using

Mill power Usually plant operators use mill power readings as an indicator of ball filling degree and often try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between Mill Power Draw Models. The mill power draw models are used to predict how much power will be consumed by a particular type of mill mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models.
