(a) KILN RINGS: High-ash coals are more likely to result in ash rings within the kiln. (b) COAL FINENESS: Low volatile matter coals need to be ground finer. The 'rule of thumb' is that the R90 um target should be half of the volatile matter content, which in your case means you would have to grind the anthracite to ~3.5% on 90um sieve.

Kiln Speed is from 2,9 to 3,1 rpm.secondary Temp is ~ 1200 degree centigrades.

Cement Plants: Coal

London coal gas production began in 1813 and by 1842 was producing 300,000 tons of coke a year, so coke was also readily available, and, being essentially a waste product, was cheaper than coal. Early cement plants used coal for drying slurry and for power generation, and coke for kiln burning. Per tonne of clinker produced, consumption was

The Rosendale Cement Industry The Neversink Valley

Rosendale cement was the most famous cement of its day and was the benchmark for all other natural cements. Between 1870 and 1872, Rosendale cement was used in building the piers for the Brooklyn Bridge. These massive 45 and 78-foot deep foundations were built of solid concrete. The 276-foot masonry towers also used mortar made of Rosendale cement.
