How Does A Cement Rotary Kiln Work?

Cement rotary kiln is an important equipment in cement production line. It is commonly used for calcining cement clinker. It can be divided into: dry cement rotary kiln and wet cement rotary kiln. Both can produce cement clinker. Cement raw materials are composed of: limestone, clay, iron raw materials. The raw materials are mixed according to the appropriate proportion. It is then fired to a molten state. It is then cooled by a cooling system to obtain a semi-finished product.

Cement rotary kiln is also known as: cement rotary kiln. It is a machine that can thermally process both bulk and slurry materials. There are many different types of cement rotary kilns. It mainly consists of a combination of: kiln body, burner, drive, kiln hood, pulley, combustion chamber, feed chamber and so on. The cement rotary kiln has a large size. It can be customised according to different production requirements. Its main body material is made of: steel plate rolls. The inner wall is made of refractory bricks. The whole kiln adopts inclined angle from feeding to discharging. It is mounted on a tug wheel by means of a wheel belt. The kiln is rotated at a slow speed by a rotating device. The kiln body is the heated part, which is constantly rotated so that the internal material is fully and evenly calcined. The rotary kiln rotating speed and material heating time can be controlled by adjusting the rotating speed of the gear ring.

How does cement rotary kiln work?
Firstly, the cement raw material is fed into the cement rotary kiln through the feeding conveyor. The kiln body is mounted on a drag wheel at an angle to the cement. The kiln body is rotated by the drive unit. The raw materials are continuously turned over along the direction of rotation of the cylinder. It moves along the axis from the kiln head to the kiln tail. At the kiln head there is a burner to spray fuel oil or coal dust into the ignited body of the kiln. The flame and hot air stream formed flows towards the end of the kiln. The raw materials tumble along the circumference and move along the axis from the kiln head to the kiln tail. In the process of moving is heated and calcined. The raw meal is continuously heated and calcined sending out physico-chemical reactions. The calcined clinker is finally discharged from the end of the kiln. Then the material can be cooled through the cooling system. The kiln is equipped with sealing devices for the inlet part and the outlet. Temperature detection and sampling hole devices are set inside the cylinder. The kiln hood is equipped with a pressure detection element. Larger kilns are also equipped with infrared thermometers to monitor and measure the temperature of the cement rotary kiln.
