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 Bottom Ash for Portland Cement Production

The specific surface Blaine of the cement was 4,050 m 2 /kg; fineness of the collected coal fly ash was 3,976 m 2 /kg. The coal bottom ash was ground in a ball mill up to a Blaine fineness of 3,463 m 2 /kg, similar to that of the Portland cement (5–8% residue on 45 μm sieve).. Several coal fly and ground coal bottom ashes were mixed in the laboratory using a powder mixer.

Coal is frequently treated or "washed", in most cases to remove some of the ash to make it saleable or to increase its value. There are several examples where coal is untreated, mostly where it is used by a power station or cement works adjacent to or close to the mine site. In most other cases, some degree of treatment is carried out.
