Cement Clinker Quality Control During Clinker Production

Under normal conditions, the clinker is calcined in the oxidation atmosphere, that is, there is sufficient oxygen in the rotary kiln to make the fuel completely burn. If the oxygen content in the kiln is insufficient, the fuel will not be able to be completely combusted and will generate CO to form a reduction atmosphere inside the kiln.

Manufacturing of Portland Cement Process and Materials

The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker by broking of chemical bonds of

The cement kiln

Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the hot end where it eventually drops out and cools. They were introduced in the 1890s
