We want to grind 300 mesh Dolomite power to fineness of 500 mesh in the Continuous Ball Mill having stone lining. Grinding media being used are river pebbles.
We are going to procure 300 mesh powder produced in the hammer/roller mill. The 300 mesh powder grinding analysis is as follow (analyzed on Malvern Instrument).
D-97 : 69 microns D-50 : 5 microns
10 Microns : 30 -35% 20 Microns : 60%
What is the maximum % of 10 microns that can be generated by way of Ball Mill Grinding (with pebbles). Objective is to have optimum grinding so as to get best yield of 10 microns by way of Centrifugal Air Classification Process.
Ball Mill is of following configuration:
Inside Diameter : 5.0 fts Length : 13.5 fts
Mill RPM : 22 rpm Motor Power : 55 kW
Th material being charged in the Mill is axially through pinion and the discharge is through slits in the periphery of the Mill Shell.
Please advice what should be the ratio of pebbles to powder, the size of the pebbles and residence time of the material in the mill (or throughput rate) so as to achieve the optimum grinding.

Thanks a lot in advance for the guidance.
