Reducing the SO2 emission from a cement kiln
Cement manufacturing is an energy intensive process; about 80% of the total energy required in the cement production is consumed in the thermal conversion of raw feed into clinker. Typically a wet kiln consumes 1400kcal/kg clinker produced compared to a modern kiln (with preheater and precalciner) which consumes only 700kcal/kg clinker produced ...
Nghĩa của từ Production
production. Giải thích VN: The property of an origin which produces a trip for a particular activity.This is usually a function of the population at the origin. For example, a production for two adults and one child might be one trip per week for groceries, two trips per day for work, three trips per six months to see a dentist, and so on.

Powerpoint presentation on CEMENT {PPT}
Cement is a mixture of calcareous, siliceous, and argillaceous substances that is used as a binding agent in construction. It is produced through a process involving mixing raw materials, burning in a rotary kiln, and grinding the clinker produced. The manufacturing process can be either dry or wet.
How Cement is Made
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 …
