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 …

The mill itself is equipped with a lifting armoring in the fi rst chamber with larger balls with a high comminuting effect. The second chamber is equipped with classifying armoring using smaller balls for fi nish grinding. The partition diaphragm is equipped with a controllable material fl ow so that both chambers maintain an optimum fi lling ratio.
