Cement kiln dust (CKD) is a fine-grained material produced during the manufacture of cement. Current reuse options are limited and the bulk of CKD not reused in the cement manufacturing process is sent to landfills or stored on-site. Due to the calcium oxide (CaO) content of CKD, it has the potentia …

Cement Kilns Exhaust gas handling

The rate of dust pick-up is controlled by the shape of the feed particle size distribution curve and the individual particle terminal velocity. The concentrations of bigger kilns in the 1930s gave the cement industry a bad reputation for dust emission, with drifts of dust in the streets of the main industrial areas.

Apr 03, 2020 In this study, indirect carbonation was carried out by using cement kiln dust (CKD), an alkaline industrial by-product, and three chelating agents (citrate, malonate, and adipate salts) as solvents at the room temperature and atmospheric pressure. We derived the optimum conditions for eluting Ca from CKD, as well as those for storing CO2 and producing CaCO3 through carbonation.

Studies on the Effect of Cement Kiln Dust on Vegetation

Cement-Kiln Dust on Vegetation Most of the recent work on the effects of cement-kiln dust has been confined to Germany and results differ considerably. There appears to be little doubt that naturally deposited dust from certain cement plants is responsible for leaf injury to deciduous and coniferous species and occasionally for death of the latter.
