### critical speed millwhat

critical speed of a ball mill is important. A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inside surface and no balls will fall from its position onto the shell.

### Influence of Kiln Speed on The Operation of Rotational ...

· The output of clinker is between 880920 ton / day before rotary kiln speed increase, but 1000—1020 ton / day after speed increasing. Clinker strength has been greatly improved, and grindability has also been improved, so each cement mill production from 38 ton/ hour to 40 ton/hour. Second, the influence on the flame and kiln skin
