Basic theoretical knowledge of the Rotary Kiln. Cement Rotary Kiln is a cylindrical vessel made of rolled steel plate, welded together to form a cylinder whose installation is slightly inclined to 24% to the horizontal to enhance movement of material as the cylinder rotates along its axis.
The cement kiln is mainly used for calcining cement clinker, and it is divided into two types: dry production cement kiln and wet production cement kiln. However, the structural characteristics of most rotary kiln are similar. Let us introduce the main structure of the rotary kiln. The main structure of the rotary kiln generally includes three ...
Our company provides different types of dry process cement rotary kilns and wet process cement rotary kilns adopted in cement plants according to customers'' requirements. The dry process of cement is to grind raw meal into dry powder and then put it into a preheater or cement kiln for calcination.
Rotary Kiln belongs to building material equipment, according to different materials, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln is used for making cement clinker and there are dry and wet methods to make cement clinker. Metallurgy chemical kiln is widely used for magnetic roasting of poor iron ore and oxidizing roasting of chrome and nickel in ...
The Inner Structure of Cement Rotary Kiln . Cement Rotary Kiln is made of drum, support bearing, hydraulic thrust device, transmission, movable kiln head, kiln end seal, and pulverized coal injection device. The kiln body is slightly inclined to the horizontal, .
Wet process kilns. The original rotary cement kilns were called ''wet process'' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter.

Cement rotary kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silicabearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and
Preheating Zone/Kiln Inlet Zone. The first reaction zone of rotary kiln system is known as the preheating zone. Here the charge gets heated up to about 800℃ before entering the calcining zone. Bricks in this area are prone to chemical attack from gases containing alkali and sulphur.
Design features of rotary cement kilns. The shell of the kiln is made of mild steel plate. Mild steel is the only viable material for the purpose, but presents the problem that the maximum temperature of the feed inside the kiln is over 1400°C, while the gas temperatures reach 1900°C.
