ball mill morrell method in gambia. This guideline condenses the works of the Morrell method for predicting the specific energy consumption of conventional crushing High Pressure Grinding Rolls HGPRs and tumbling mill equipment and applies them to assessing operating comminution circuit performance Such circuits include combinations of any of the following equipment Autogenous Grinding AG and

Abstract Ball mills, like other comminution devices, consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge. The motion of the charge is rigorously simulated with a

Comparison of the ball mill power draw from the Denver slide rule and the proposed model. Dashed line corresponds to yx.

3.3 Ball Mill Design The ball mill designs also follow the Bond/Rowlings method with comparison with other methods. Again the method of use is the same 3.4 SAG/BM Combined design This is the combined model of the SAG and BM models. The difference is that a provision in the BM model allows for the fact that finished product is in the BM feed.

TECHNICAL NOTES 8 GRINDING R. P. King

However the energy efficiency of comminution circuits also varies depending on the flowhseet design of the circuit. So for example it is generally recognised that a crush-HPGR-ball mill circuit is more energy efficient than, say, one comprising crush-sag mill-ball-mill (Morrell,2008

This is a SAG or AG mill model that estimates the specific energy consumption (E SAG) using the equations of Morrell (2004). Testwork Required. The SMC™ test, stored in the DWT testwork table (SMC is a Drop Weight Test). Bond ball mill work index. The method requires all the parameters of the ball mill

The Morrell Method for grinding mills is based on predicting the specific energy at the pinion shaft. To adjust the power draw measured at the motor input to power at the pinion a 6.5% correction was made. In the case of crushers the Morrell Method relates to motor input power less no-load power (net power).

Apr 01, 1999 The ball load, at which the mill draws maximum power, is about 53%. The simulation results of 0.762-m mill running at 60% critical speed are plotted in Fig. 4. The relevant operating and simulation parameters are listed in Table 3. The calculated power draft is maximum at about 50% ball load.

For rod and ball mill tests, the standard Bond rod and ball mill tests are followed. [Morrell, S. 2008a. A method for predicting the specific energy requirement of comminution circuits and
