chinaware ball mill critical speed

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 shell. Ball mill machines usually operates at 65-75% of critical speed. What is the ball mill price?

We believes the value of brand, which originates from not only excellent products and solutions, but also considerate pre-sales & after-sales technical services. After the sales, we will also have a 24-hour online after-sales service team to serve you. please be relief, Our service will make you satisfied.

    ball mill rotating critical speed- bio7-biogas.be

    The critical speed (rpm) is given by: n C = 42.29/ √ d, where d is the internal diameter in metres. Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size - mills including
