Grinding efficiency. Ball mill | by A.Sen | Medium

The mills where conventional separators are used, a little finer grinding is suggested due to shorter classifying zone available. While analyzing both the axial graphs for finer grinding (second compartment) performance this is found cement residue at mill discharge is complying the range as marked and very satisfactory.

Ball Mills - an overview | ScienceDirect Topics

In the second chamber the ball diameters are of smaller diameter, between 60 and 15 mm. In this chamber the lining is typically a ‘classifying lining’ which sorts the media so that ball size reduces towards the discharge end of the mill. Here, comminution takes place in the rolling point-contact zone between each charge ball.
