Mono-Chamber Ball Mill Page 1 of 2

Re: Mono-Chamber Ball Mill. Hi Fjalali, Thanks for sharing the more information.If feed is d80 (80% passing size) of 4000 micron than calculated maximum ball size of 50 mm seems o.k.Technically for such fine feed mono chamber mill a combination of lifting and classifying liner will be a good option.However, there is no standard grinding media size distribution is available in literature.For

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.

Cement mill Wikipedia

A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel.The smaller grades are occasionally cylindrical ("pebs
