    Charge Dynamics in Tumbling Mills DiVA portal

    The most common types of tumbling mills are the rod-, ball- and autogenous mills. Depending on the type of ore, there are different charge media to be used. In rod and ball mills, the different charge media are usually made of steel and added to the mill. In autogenous mills, the ore itself is used as charge

    The radius and angle position of the mill charge centre of mass is commonly used for the ball mill dynamic model during start-up. This model considers that the mill load maintains its resting shape and that the mill is lifted to a certain angle depending on the mill speed and existing operating conditions during its rotation [ 3 ].
