I was just wanting to get peoples thoughts on both processes and the pro's and con's of each. We have been using the Mill to residue technique but that is affecting some of our customers. Hence we changed back to Mill to Blaine, but have halved our output capacity and increased operating costs.
Any comments would be apreciated....
There are advantages and drawbacks to controlling cement fineness to Blaine or to residue. Really you need to control to both by varying the fresh feed rate and the recirculating load.
Best regards

Normally a steeper distribution is expected to give a lower blaine than a wider distribution, the extent depends on the type of circuit u r operating with.surely basic operations with feed rate and recirculation will help as Mr.clark suggests.
but the mill output getting down to half, suggests possible grinding inefficiency of the mill. try to optimise on the grindability and air balance of the mill circuit and also check if u r really grinding it too fine than earlier.
what is the type of mill u r operating and what is the fineness level in both cases?.
