### Critical speed of a ball mill.

Jan 01 2016 the internal diameter of the ball mill was 503 m and the length-to-diameter ratio was 0The steel balls occupied 18 of the millThe total load occupied 45 of the mill volumeIf the mill operated at 72 of the critical speed determine: 1The mill power at the shaft during wet grinding 2The mill power at the shaft during dry grinding.

The critical speed of ball mill is given by where r radius of ball mill; r radius of ballFor r 1000 mm and r 50 mm n c 30Ball mill critical speed - mineral processing amp; metallurgy.

The critical speed of the ball mill is less than 45 of operating speedNow calculate the operating speed of the ball mill which has diameter of 900 mm.

### What is critical speed of ball mill.

The critical speed of the ball mill is the speed at which the centrifugal force is equal to the gravity on the inner surface of the mill so that no ball falls from its position onto the mill shellBall mill machines usually operates at 65-75 of critical speed.
