Cement rotary kiln types

Cement rotary kiln, also called clinker kiln, can be divided into dry-process cement kiln and wet-process cement kiln according to the cement production technology. Dry-process cement rotary kiln is mainly used to calcine cement clinker. As the core equipment of NSP cement production line, cement rotary kiln is consist of shell, supporting device, transmission device, lubrication device, moving kiln head, sealing device for kiln tail, burning device and etc. dry-process cement rotary kiln has advantages of simple structure, reliable operation and easy to automatic control in the cement production line.

Cement rotary kiln fuctions

Cement rotary kiln parts

cement rotary kiln structure

A cement rotary kiln is composed of the following parts:

  • body
  • tyre
  • carrying roller
  • thrust roller
  • sealing device
  • gearing
  • accessory equipment. 

Working principle of cement rotary kiln

  1. During working of cement rotary kiln, pulverized coal (natural gas) is burned in the cement rotary kiln to generate heat.
  2. The heat is used to heat the material by gas conduction or radiation.
  3. At the same time, as the kiln body rotates according to the designed inclination and rotation speed, the raw materials rolling forward periodically in the kiln.
  4. So that the raw material is transported from the feeding end to the discharging end, meanwhile, it is ensured that the raw material is calcined into qualified clinker in the time when the raw material passes through the rotary kiln, thereby achieving the purpose of high yield, high quality, and low consumption.

maintenance of cement rotary kiln

Cement rotary kiln is a piece of cement equipment with strong durability, also plays a vital role in the cement plant. If you find any problem in the operation, solve it immediately. In general, the maintenance of rotary kiln is a complex process, here are some tips will be helpful.

Refractory material

First of all, check the fire hole of the rotary kiln is closed or not, ensure the close state to avoid too much cold air. Then, check the windshield of the burner at the kiln door is close to the kiln door. If the air leakage is not closed, it should be pushed to the position of close contact with the kiln door. Third, check the door cover of rotary kiln, if there is the phenomenon of positive pressure ash, should inform the central control to adjust properly. Finally, remember to check air leakage or wear out the phenomenon of resistant material, when you find the above problems, promptly inform the relevant leadership to deal with them.

Sealing and wearing parts

Check the fish scales sealed in the kiln head, and then check the fitting condition of the fish scales in the rotary kiln and friction ring. If there is any bad condition such as non-fitting, the weight should be adjusted by tightening the device to make it fit. If there is too much aggregate in the reliable rotary kiln, the discharging pipe should be adjusted timely. After that, check the wear condition of the friction ring of rotary kiln. If the friction ring is found to be badly worn or worn out, replace it.

Internal parts

Check the cooling air at the kiln head, and then check the friction between kiln head and the kiln door cover. In order to ensure safety, check the oil film contact of the supporting wheel shaft and thrust plate one by one. Check oil level, oil scoop and oil distribution of rotary kiln. Next, check whether there are impurities, water droplets, oil leakage, collision, loosening and other abnormal conditions, if necessary, the temperature can be measured and control.
