COAL GRINDING AND DRYING IN CEMENT INDUSTRY

The preparation of coal in cement works comprises the grinding and drying of raw coal delivered to the works. In cases where the coal consumption rates are high and coal from different sources are used, it is advantageous to blend the various coals in conjunction with stockpiling so as to obtain a fuel that is physically and chemically as closely uniform as possible and thus, to achieve well

Advanced technology recycles coal ash for use in concrete

Recycling coal ash for concrete is practical and safe, but excess carbon in the ash must be removed before it's suitable for reuse. In most cases, coal ash is between 6% and 15% carbon, which is too high to meet specifications for concrete. The STAR unit reduces the carbon level below 1%.

Q&A Why cement emissions matter for climate change

A further 40% of cement emissions come from burning fossil fuels to heat kilns to the high temperatures needed for this calcination process. The last 10% of emissions come from fuels needed to mine and transport the raw materials. Therefore, cement emissions depend largely on the proportion of clinker used in each tonne of cement.
