The vertical shaft kiln produced by AGICO has the advantages of : Energy-saving. The cold air usually enters the kiln from the bottom. After heat exchange, the temperature of the clinker will be cooled down, and the cold air will be preheated and enter the calcining zone to participate in combustion.

From the turn of the 20th century, rotary cement kilns gradually replaced the original vertical shaft kilns, used originally for making lime. Rotary kilns heat the clinker mainly by radiative heat transfer and this is more efficient at higher temperatures, enabling higher burning temperatures to be achieved.

3. Grinding: The clinkers as obtained from the rotary kiln are finely ground in ball mills and tube mills. During grinding, a small quantity, about 3 to 4 per cent, of gypsum is added. The gypsum controls the initial setting time of cement. If gypsum is not added, the cement would set as soon as water is added.

Hobbyists know a kiln as a small, high-temperature oven used to bake ceramics. But an industrial kiln is a massive oven or furnace known as a rotary kiln designed for the continuous processing of a material. Rotary kilns are cylindrical furnaces constructed of a steel shell and a refractory lining that rotates along the long axis.

there are at least 2 principle reasopns why the clinker from a vsk might have a low lime combination factor: (i) the difficulty of achieving the high temperature required to achieve a high degree of combination, and (ii) the lack of the tumbling action which is achieved in a rotary kiln, which in turn promotes the combination via the sintering .
