industries (20-30%). Cement industry is one of the most important industries involved in air pollution. The aerial discharge of cement factories consist of Particulate matter, Sulphur dioxide and Nitrogen oxides producing continuous visible clouds which ultimately settle on the vegetation, soil and effects whole biotic life around, as a result
Sulfur dioxide emissions are best controlled by the use of low sulfur fuels and low sulfur raw materials. The absorption capacity of the cement must be assessed to determine the quantity of sulfur dioxide emitted which may be up to about half the sulfur load on the kiln. Precalcining with low-NOx secondary firing can reduce NOx emissions.
May 26, 2017· The Effects of Sulfur Dioxide on Human Beings; Sulfur dioxide is pretty harmful gas when it comes to its effects on human. If you are not careful enough and accidentally inhale this particular chemical, it could surely affects your health. The effects of Sulfur Dioxide could be felt very quickly (around 10-15 minutes after breathing it in).

Portland cement and the environment. Portland cement is manufactured by heating limestone or chalk with clay in a rotary kiln to a high temperature (about 1450°C) to produce hard nodules of clinker that are then ground with a little gypsum in a ball mill. The firing process consumes significant quantities of fuel, usually coal or petroleum coke.
