Cement kiln dust is a by-product of cement clinker production, and has about 35 wt% of CaO and 2 wt% of MgO. Therefore, cement kiln dust has a high CO 2 storage capacity between 191 and 256 kg CO 2 /tonne of cement kiln dust. 11 Another source of Ca-based industrial waste is the paper industry.
To achieve the combustion of only slightly treated waste fuels and substitute fuels in a rotary kiln for cement production, the substitute fuel is fed into the calcining zone of the rotary kiln which, for this purpose, has on its outside in this zone at least one fuel pick-up which rotates together with the kiln
Cement is then pumped to silos for storage and dispatch. Mineral additions and s are added to reduce the amount of clinker in cement. This in turn reduces the fuel, power, process emissions and raw materials associated with cement production. At the same time it creates a use for material considered to be a waste product of other industries.
The raw materials, limestone and shale for example, are ground finely and blended to produce the raw meal. The raw meal is fed in at the top of the preheater tower and passes through the series of cyclones in the tower. Hot gas from the kiln and, often, hot air from the clinker
