  • CaO–LOI classification system for cement kiln dust

    Cement Kiln Dust (CKD), a residual of cement production, has been used effectively as a cement replacement, but there is a lack of guidance for its appropriate selection and performance in specific engineering applications. Since CKD is not a controlled product, the chemical composition and material properties differ from source to source like coal fly ash. This paper presents a dual–letter ...

  • Equilibrium analysis for heavy metal cation removal using cement kiln dust

    Ion exchange, reverse osmosis, and chemical precipitation have been investigated extensively for heavy metal uptake. However, they are deemed too expensive to meet stringent effluent characteristics. In this study, cement kiln dust (CKD) was examined for the removal of target heavy metals. Adsorption studies in completely mixed batch reactors were used to generate equilibrium pH adsorption ...

  • Air pollution control through kiln recycling by-pass dust in a cement factory

    Over the centuries, air pollution has increased from a local nuisance to a global problem (Emberlin 1998). Cement industry is one of the most important and strategic industries in Iran. However, its air pollution has been a serious problem. The primary related pollution is dust, which industrial countries have allocated tremendous efforts in reducing its volume. Dust in different stages of a ...

  • Comparative performance of cement kiln dust and activated carbon in removal of cadmium from aqueous solutions

    This study compared the performance of cement kiln dust (CKD) as industrial byproduct and commercially activated carbon (AC) as adsorbent derived from agricultural waste for the removal of cadmium (Cd2+) from aqueous solutions. CKD and AC were characterized by Fourier transform infrared (FTIR) and scanning electron microscopy (SEM) and surface areas demonstrate the differences of ...

  • Effects of exposure to portland cement dust on lung function in portland cement factory workers in khash, Iran

    Portland cement is a light grey powder produced by crushing and grinding calcareous materials such as limestone, chalk and argillaceous materials such as; clay and shale, as a wet slurry or in a dry state. The mixture is calcined in a rotary kiln and the resulting clinker is finely ground. The product is composed largely of calcium silicates, calcium aluminates, calcium sulfates, oxides of sodium ...

  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...
