Cement producers should build the digital

If hourly cement sample fineness is checked on 45 microns then from above chart a target may arrived around 10 % residue to maintain. With increase use of blended cement, either it is limestone as filler which is much softer than clinker or very fine grain fly-ash — these may increase the Blaine value (surface area) but little to contribute ...

- Increase in separator speed: higher circulating load is obtained by increasing the mass of material in the reject stream. This allows to modify the cement particle size distribution, thus obtaining a finer and better performing cement. Grinding aids act at two levels: in the mill, with the reduction of cement coating on grinding

Re: Cement mill Residue. Hi Jatinder, You could increase the speed of your separator rotor, i.e. increase recirculation load. But you may then experience an excessively high blaine value. The best way to make a balance on mesh passing and blaine is to play around with feed tonnage and separator rotor speed. Branco. Reply

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

The differential pressure between the inlet and outlet of the mill (ΔP mill) is an important process variable for the testing of grinding aids.ΔP mill reflects the load and the filling level of the mill. At unchanged separator settings, the increase of ΔP mill indicates more internal circulations and more fines. As a result of the higher ΔP mill, the mill vibration increases (8-10mm/s ...
