Gambar Production Of Cement By The Dry Process

Apr 12, 2021

The cement making process can be divided; first “clinker” is made at temperatures of 1400 o C. Then the clinker is milled with other minerals to produce the powder we know as cement. Cement production requires water for cooling heavy equipment and exhaust gases, in emission control systems such as wet scrubbers, as well as for preparing
