Cement grinding aids are classified into three key types based on the feedstock, such as amine-based, alcohol-based and ether-based grinding aids. The prime factor behind the usage of cement grinding aids is the elimination of the coating effect of clinker on grinding mill walls and to increase the production rate of cement keeping the surface ...

To this end, pure molasses and molasses with formaldehyde (to prevent fermantation) were added to concrete mixtures at the rates 0.5% and 1%. First, the effect of molasses on fresh and hardened concrete properties was established, then, additional specimens were obtained during production for strength tests and were cured in acid and sulfate ...

production cost. The efficiency of the cement production depends greatly upon the efficiency of a grinding mill which consumes 60-70% of the total electricity consumption of the cement plant[12]. A grinding mill (Ball Mill) is used to grind the cement clinker into fine cement powder. Grinding Aids are used to improve the grinding

production is as a cement grinding aid (CGA). CGAs are supplementary organic substances (gas, liquid, or solid) added into the mill at low dosage (0.01-0.05%) during cement particle grinding process. CGA improves the efficiency of this grinding process, reduces particle size, and reduces energy use
