Bituminous Coal Characteristics and Applications

Bituminous coal can be categorized further by the level of volatile matter; it contains high-volatile A, B, and C, medium-volatile, and low-volatile. Volatile matter includes any material that is liberated from the coal at high temperatures. In the case of coal, the volatile matter may include sulfur and hydrocarbons.

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.

Coal in the cement industry

Coal fineness has a direct relationship with its reactivity. Hence in the cement plant a special significance has been given to the milling behavior of coal. It has been observed that low volatile matter in coal can be co mpensated by finer grinding. It is also desirable that coal must have a …

High ash coal - Page 1 of 1 - International Cement …

re High ash coal. Hi Filippo, With low volatile matter/high ash coals you have to consider the following;-(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 ...
