Martin Earles first installed them for autonomous cement grinding in 1899, and in 1904, they were used exclusively at Norman for rawmilling, coal and cement grinding. As the mills "ran cold", for raw milling, the material had to be completely predried. A slightly more equivocal commitment to these mills occurred at Ellesmere Port in 1912. The ...

Material is directly conveyed to the silos (silos are the large storage tanks of cement) from the grinding mills. Further, it is packed to about 2040 kg bags. Only a small percent of cement is packed in the bags only for those customers whom need is very small. The remaining cement is shipped in bulk quantities by mean of trucks, rails or ships.

There is a horizontal grinding mill filled with steel balls. Clinker reach in this rotating drum after cooling. During grinding, gypsum is also added to the mix in small percentage that controls the setting of cement. Here, steel balls tumble and crush the clinker and gypsum mixture into a very fine powder. This fine powder is considered as cement.

Grinding of clinker consumes power in the range of kWh/ton of clinker produced. These and other pyroprocessing parameters make cement production costly. The pyroprocessing process in kilns and the grinding technologies therefore have to be optimized for best processing. This paper discusses the cement manufacturing and grinding processes.

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 superfine 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.
