Clinker grinding with limestone - Page 1 of 1

Dec 08, 2014  re Clinker grinding with limestone. 100oC seems a bit low. Normally you should try to keep the mill outlet temperature at between 110 and 115oC. Have you tested the water content of the cement blocking the diaphragm? If you use water sprays they may not be atomising correctly, causing localised buildup of moist cement.

Portland cement clinker was first made (in 1825) in a modified form of the traditional static lime kiln. The basic, egg-cup shaped lime kiln was provided with a conical or beehive shaped extension to increase draught and thus obtain the higher temperature needed to make cement clinker. For nearly half a century, this design, and minor ...

The cooling of cement is an important step prior to storage in mitigating gypsum dehydration and subsequent moisture liberation which can lead to lump formation. Recommendations vary but it is generally accepted that with mill outlet temperatures of around 110ºC – 120ºC, cooling to below 80ºC is necessary to avoid this reaction.

Low temperature cement grinding - Page 1 of 1

Re: Low temperature cement grinding. Hi Gio, Hope this is same Gio I met Natal SA. Normally when clinker grinding in verucal mills, the mill outlet temperature is around 80-85 deg C only. What I feel is try to optimise the dam ring height of the mill to have proper partical size distribution. This will help to increase the strength.
