### THE MODE OF BALL MILL OPERATION

9/10/2020 · The operating-mode selection of the ball mill (sometimes called «the operating-mode 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 ...

### Bal-tec - Ball Weight and Density

Ball Weight and Density How much will a ball of a given diameter in a certain material weigh? The answer is calculated by multiplying the volume of the ball by the density of the material. $\text"Weight" = \text"Volume" ⋅ \text"Density"$ For example, calculate the weight of a two inch diameter lead ball: $\text"Volume" = {4 ⋅ π ⋅ R^3 }/ 3$
