2022年10月20日 1 Introduction Although the cement industry globally is one of the most important parts of the economic sector, cement production is an extremely CO 2 emission process Several investigations have been conducted to reduce cement production issues (Chipakwe et al Citation 2020)They were focused mainly on cement chemistry, and few
2019年9月1日 Cement kiln coprocessing is a common carbon reduction strategy that has become increasingly popular in recent years However, the disposal of Na 2 Ocontaining solid wastes and fuels has resulted in elevated Na 2 O content in clinker, leading to the generation of highsodium Portland cement clinker To address this issue, the addition of
The Portland cement manufacturing process can be divided into 6 steps: raw material crushing, prehomogenization, fine grinding, clinker production, cement grinding, cement packing, etc In these processes, we need the assistance of different kinds of cement equipment, such as cement kilns, cement mills, and cement crushers
2015年8月20日 Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering
