Dear All,

We have ball mills (capacity-50tph) which we operate for bauxite ( Alumina Ore) wet grinding, generally the feed sige for the ball mill is in the range of < 1 inch and product in the range of 250 micron ( >70% product)

 

But we are not able to operate the ball mills with full capacity as most of the time lot much quantity of un-ground (oversige) particles coming out from trommel screen located at ball mill discharge.

 

Can anyone suggest for reducing  this unground particles from trommel screen ?
