CO2 emissions from cement production are mainly derived from calcination of limestone, coal for calcination, and coalconsuming electricity. Therefore, the grinding aid increases the amount of mixed materials and reduces the power consumption, which can greatly reduce the CO2 emissions from cement production.
Cement is a fine powder, obtained from the calcination at 1,450°C of a mix of limestone, clay, and iron ore. The product of the calcination process is clinker—the main ingredient of cement—that is finely ground with gypsum and other chemical additives to produce cement.
Grinding, Proportioning and Blending. The crushed raw ingredients are made ready for the cement making process in the kiln by combining them with additives and grinding them to ensure a fine homogenous mixture. The composition of cement is proportioned here depending on the desired properties of the cement. Generally, limestone is 80% and remaining 20% is the clay.
MIT Concrete Sustainability Hub, Concrete Science Platform White Paper Improving Concrete Sustainability through Alite and Belite Reactivity September 2013 . Executive Summary Calcium silicate phases, alite and belite, are among the main components of modern portland cements.
Grinding efficiency is important for all comminution processes in a cement plant, raw material, coal and cement grinding. While the requirements are basically the same in all cases, cement grinding has a special additional focus, which is workability of the final product and its strength development.
