THE MODE OF BALL MILL OPERATION
2020910 · The operatingmode selection of the ball mill (sometimes called “the operatingmode of grinding media”) depends on three main parameters: The relative frequency speed of drum is equal to the ratio between the actual speed to critical speed of mill drum. Proxy critical rotation frequency of rotation of the drum is equivalent to a speed at which the inertia of balls rotational motion equals

Optimization of mill performance by using
2021521 · Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
