Design aspects of large ball mills.

01/10/1999 · The design of ball mill drives is, in many ways, more difficult than for AG and SAG units. This stems from the fact that the ball mill is generally smaller in diameter, so that the notional tangential force at the shell is higher for a given power input (although this effect is somewhat offset by the ball mill's higher rotational speed). Specifiion Units SAG mill Ball .
