Keywords: Clinker, dynamics, Feed, mill, residence, time. 1.0 INTRODUCTION The main raw material for cement production is clinker. Cement clinker is usually grounded using a ball mill. This is essentially a large rotating drum containing grinding media; normally steel balls. As the drum rotates, the balls cascade and crush the clinker.

The same lots of Portland cement clinker and natural gypsum (CaSO 4.2H 2 O) were used in this industrial-plant-scale experimental work to eliminate the potential effects of variations in the feed to the grinding systems. Chemical compositions of the clinker and the gypsum, measured by X-ray fluorescence analysis, are given in Table 1.Dehydration behavior …

Step 6 : Finish Grinding. The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.

distribution of cement particles; smaller particles have larger surface area. If the particle size distribution is known, the Blaine index can be successfully predicted (Zhang and Napier-Munn, 1995). The cement clinker grinding circuit reduces the feed from 80% passing size between 10 and 20mm to 100% passing 90microns.

CONCLUSIONS Clinker quality is an important parameter to consider the set points for target fineness. Quality of the clinker plays an important role on the residue and particle size distribution of the cements. Clinker (CCL-1) contains high C2S shows drastic diffrence on the residue while incresing the fineness from 225 to 250 m2/kg.

The calcium silicate compositions created in the rotary kiln emerge in a "clinker" form, that is, in small granules with diameters of approximately 1 to 4 mm. The clinker is then ground to a powder with a mean particle size of approximately 12 μm. To produce concrete, this material is mixed with aggregates, sand and water.
