The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge. C = distance of centre of gravity or charge from centre of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in RPM. HP = A x B x C x L. Where.

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

The working principles of the Dyno Mill/ Dyna mill machine are based on the highspeed rotation of the agitator shaft, which imparts kinetic energy to the grinding beads. The energy is transferred to the particles or agglomerates, causing them to collide and break apart. This process is known as bead milling or wet grinding.
