analysis of tumbling mills
The earliest analysis of ball motion in tumbling mills dates back to early 1900. Lack of understanding of these elementary processes makes the designing approach a bit empirical. Charge motion analysis The motion of grinding media and the energy distribution have a profound influence on the comminution of particles in tumbling mills.

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R,,

charge motion due to operating parameters. There is no data related to liner design such as the toe and shoulder regions. Production is disrupted for the duration of the procedure: grindout, mill stoppage, mill startup and the transition period to steady state. Stresses, generated in the ball charge, increase, which may result in spalling of balls and blocking the grate discharge ...

of charge in tumbling mill
As in situ characterisation of charge motion has proved difficult due to the aggressive internal environment of tumbling mills, many models have focused on using empirical relationships to describe the distribution of power draw into the charge. Thus, the charge has often been simplified to a single bulk body over a defined region of the mill. Tumbling mills are still the mostly used milling ...

Development of a method to measure charges in tumbling mills
Common Methods to Measure Tumbling Mills Charges. The charge level of a mill can be described as the volume occupied by the grinding media (including empty spaces) as a fraction of the total volume available inside the equipment. Assuming this definition, other measurements may be taken considering the total charge that includes the rock charge; in this case, applicable to SAG and AG mills ...

The charge motion in a tumbling mill has been mostly described by empirical, mechanistic and computational models. The computational model presented in this work is a three phase approach for the tumbling mill that combines a particle description for the solids modelled by the Discrete Element Method, and the continuum description for the fluid by CFD approach. In the present work a phase ...

· The dynamics of charge motion in tumbling mills has been a challenging problem both experimentally and theoretically. The harsh environment within the mill precluded sophistied sensors. On the other hand, first principle modeling of charge motion was only marginally successful since the motion involves hundreds of bodies colliding with each other.
