Portland cement can be manufactured by intimately mixing together calcareous and argillaceous stones containing silica, alumina, and iron oxide etc. and burning it in large rotary kilns at a temperature of approximately 1400°C to 1500°C. At his temperature the materials partially fuse, forming clinker. This clinker is cooled and ground to fine power. Usually it is gray or brownish in colour

Cement rotary kilns refer to cement rotary calcining kilns (sometimes called rotary furnaces). It is a pyroprocessing device used to heat materials to high temperatures in a continuous process. The kiln body is a cylinder vessel with a certain degree of tilt to the horizontal level. Raw materials are fed into the vessel from the upper end and moved to the lower end, being stirred and mixed

modern cement plant. The 2base rotary kiln is a statically determined beam system, where the support load is always known. It is a shorter and wider kiln, with a reduced slope to maintain the material retention time, similar to a 3base kiln. The larger diameter reduces the gas velocity and the dust recircula tion, and secures a lower burning zone thermal load (Gcal/h/m2) at the same

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
