Clinker Production | Clinker Plant | Cement Plant Equipment
As the temperature of the material increases, the mineral becomes a liquid phase and reacts to form a large amount (clinker). After the clinker is fired, the temperature begins to decrease. As a leading cement plant manufacturer, AGICO Cement supplies cement equipment for clinker plant, such as cement rotary kiln, preheater in cement plant ...
Cement Cooler
The thermal efficiency of a cement cooler refers to the percentage of the total heat recovered from the high-temperature clinker and the physical heat of the clinker. The higher the thermal efficiency, the more heat is recovered, which can be used to preheat the combustion air in cement kiln, saving energy and fuel cost.
Clinker Cooler
The rotary cooler is the earliest used one in the cement plant. It is similar to the cement rotary kiln in appearance and equipped with refractory lining and a material lifting device inside. The high-temperature clinker enters into the cylinder from one end, contacts with the cold air from the other end under the action of the lifting device ...
