2020-3-13Introduction Cement plant is also called cement manufacturing plant, which is a series of cement production equipment. It is mainly made up of crushing and pre homogenization, raw material preparation, homogenization of raw materials, preheating and decomposition, cement clinker burning, cement grinding as well as packaging process, which is the more complicated production process.

2016-5-25estimated that cement production originates about 5 of global manmade CO 2 emissions 13. The typical gaseous emissions to air from cement production include NOx, SOx, CO, CO 2, H 2 S, VOCs, dioxins, furans and particulate matters 14, 15, 16. These major pollutants can be classified in two categories- gaseous and particulates.
