2004-10-13  The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load. A direct measurement of the load entails the crash stopping of the ball mill under load whilst the mill is running under steady state conditions. Before taking measurement steady state conditions were verified by the plant staff, then the mills were crash stopped so that required measurements could be taken from the both compartments along the grinding path inside the mills. The load within the mills ## Ball mill media optimization Metcom Tech

2018-12-4  Production rate, mill power and CSE can be measured during a plant circuit survey. The mill grinding rate of coarse material is then calculated. At the circuit target P80 size, this is the mill grinding rate (of coarse material) through the size of interest. The objective is to maximize this rate. The mill grinding efficiency can also be calculated by taking the ratio of the mill grinding rate over the material’s grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al., 2000). For media sizing, maximizing the mill grinding rate on a given ore is equivalent to maximizing the mill grinding efficiency. ## A Method of C alculating Autogenous/ Semi
