Cement kiln

Definition:

Kiln used for the manufacture of Portland and other types of cement.

Cement kilns are rotary kilns consisting of a long cylinder that is nearly horizontal and rotates slowly around its axis. The raw materials are fed into the slightly higher end and gradually move down towards the lower end while being heated at high temperatures (up to 1450°C) and stirred.

Considerable quantities of fuel are needed to keep the kiln hot for the desired chemical reactions to take place.
