Abstract. This research focused the role to study the effects and ways to control the chemical composition of clinker for better cement production. Cement is a substance produced by grinding a mixture of a clay and limestone and heating to a temperature of 1450°C, in which the chemical transformation occurs inside the kiln to form new compound ...

Thus, two sulfur cycles can be observed in a NSP cement line. One is the kilnprecalciner sulfur cycle. A large proportion of SO 2 released from sulfates decomposition in the kiln is captured by CaO in the precalciner and then returns back to the kiln. The second cycle is the preheaterraw mill/baghouse sulfur cycle.

SO2 emissions from cement plants are primarily determined by the content of the volatile sulphur in the raw materials. Kilns that use raw materials with little or no volatile sulphur have SO2 emission levels well below this level without using abatement techniques. The current reported emission range is <103500 mg SO2/m 3.

the cement kiln system. Sulfur in cement kilns is derived from both kiln feed and from the kiln fuel. The form of the sulfur dictates the location in the kiln where the SO2 generation takes place. Sulfur in the fuel is oxidized in the burning zone or calciner, and is easily removed by reactive lime present in the kiln.

Cement plant exposure can have a negative influence on the health of both employees and the general public. Gaseous matter and particulate matter are unrestrained into the surroundings during cement making and carriage (Raffetti et al. 2019).NOx, SOx, CO 2, CO, H 2 S, volatile organic carbons, dioxin, furans, and particulate matter are common emissions from cement manufacturing into the air.

Stage of Cement Manufacture. There are six main stages of the cement manufacturing process. Stage 1: Raw Material Extraction/Quarry The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale, and bauxite. The ore rocks are quarried and crushed into smaller pieces of about 6 inches.
