Dry and wet ball mills have the same basic components, but there are some structural differences: 3 Discharging part Discharging port: Dry ball mill: The ball mill needs to be equipped with an air induction device, a dust exhaust pipe and a dust collector. The structure is more complicated, and the discharge port is straight.

Unless the trunnion is very small or unless you are using a grate discharge ball mill, balls will not stay in the mill, and you will spend a lot on steel to add a small amount of power. Formulas given for mill power draw modelling are empirical, and fit around field data over the normal operating range of about 30 to 45% charge level.

For small ball mills, the power draw under dry batch grinding conditions was derived by Austin et al. [5] and the same considerations apply for rod mills. Equation () indicates that like any tubular mill the variation of mill power with speed in a rod mill is almost linear. This is true at the initial stages but breaks down when the critical ...

A tumbling mill is a collective name for the generally known ball mills, rod mills, tube mills, pebble mills and autogeneous mills. For all these kinds of mills the mechanics can be dealt with together, there being no substantial difference in the grinding process. There are two kinds of grinding body movements: either they describe an ...

The typical millmotor coupling is a pinion and gear. On larger mills two motors may be used, and in that arrangement two pinions drive one gear on the mill. Synchronous motors are well suited to the ball mill, because the power draw is almost constant. Induction, squirrel cage, and slip ring motors are also used.
