Product Introduction

Mobile Rotary tunnel kiln is improved and upgraded from traditional tunnel kiln.

Its biggest characteristic is the adobes stay still while the body of rotary kiln moves.

Kiln body are all steel structure,the circular orbit,once upon a time,in turn, divided into the dry period, preheating section, after roasting,cooling,heat preservation paragraphs. Machine and kiln body synthetic operation,iin order to characterize code. Rotation movement of the kiln body in orbit intermittent forward, front eat bricks, back end spit finished bricks,in turn ,drying, preheating,roasting,cooling,the whole process of bricks.

Clients in : China, India, Myanmar, Laos, Vietnam, Cambodia. South Africa, Zimbabwe, Tanzania, Uganda. Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan.

Advantages:

1. Drying and firing won be influenced by weather condition
2. Saving drying plastic cover costs compared with hoffman or clamp kiln
3. Saving labor costs ,only need 1 labor to operate the kiln.
4. Can get more finished bricks with more than 99.8% finished brick rate
5. Less maintenance costs without kiln cars compared with tunnel kiln
6. Saving enery compared with tunnel kiln ,energy consumption is 220 ~260 kcal/kg 

More intelligent：

1.refers to the process of measuring and recording temperature and humidity levels in a given environment.

By issuing humidity alerts, we can intervene in the wet area in time to prevent deformation and collapse caused by excessive moisture, ensuring the quality of product formation.

2.High-precision vibration sensors are deployed to continuously monitor the fans operational status, enabling timely detection of mechanical anomalies.

3.The oil temperature of the key fan lubrication system is monitored online to prevent overheating damage and ensure stable operation of the equipment.

4.Dynamically adjust the servo air valve opening according to combustion requirements to accurately match the air supply and improve combustion efficiency.

The advantages of the new energy-saving mobile rotary tunnel kiln

Compared with the traditional ordinary tunnel kiln, the new energy-saving and environment-friendly mobile rotary tunnel kiln are stacked at the bottom of the ring kiln at one time, and the relative movement required in the brick-making process is completed by the movement of the kiln body, so the kiln car and its supporting facilities are not required. The section of traditional tunnel kiln is generally 2.7-4.5m. The construction cost of tunnel kiln larger than this section is very high, while the section of circular rotary mobile tunnel kiln can reach more than 12M, and the construction cost is far lower than that of tunnel kiln.

Burning bricks requires coal or other fuels. How to maximize the thermal efficiency is the technical key of brick kiln design. The sintering temperature of brick is between 850 ° C and 1050 ° C. In order to save coal, the heat insulation effect of the kiln must be improved. The rotary tunnel kiln is stacked with refractory fiber cotton, which not only reduces the weight of the kiln body, reduces the thermal expansion and contraction stress of the kiln body, but also improves the thermal insulation performance of the kiln body. The kiln temperature is maintained for a long time, and the bricks consumed at one time increase in large area. The internal combustion heat energy can more effectively improve the kiln temperature and save fuel.

In ordinary tunnel kilns, in order to prevent high-temperature flue gas from flowing into the kiln car and burning out the wheels and bearings, it is also necessary to set up a gas source under the kiln car. In the whole heating system, the air supply pressure at the bottom and surface of the vehicle must be kept balanced, and the high temperature flue gas and cold air at the bottom of the vehicle must not rise to reduce the kiln temperature.

 The bricks of the rotary tunnel kiln are directly stacked on the ground, without air supply under the vehicle, and the ground temperature is directly fully utilized. It is found that the aluminum silicate fiber blanket can still be calcined normally after 48 hours of coal and air shutdown in actual production, which is impossible for ordinary tunnel kilns. In the annular rotary tunnel kiln, when the firing temperature of bricks is reduced to room temperature, the heat released is enough to dry wet bricks of the same volume, so there is no need to build a hot air furnace, nor need to use the superheat roasting process to consume more coal to dry the heat.

The circular rotary tunnel kiln fully adopts mechanized operation and automatic digital control system. The temperature in the kiln is directly displayed on the display screen of the control system. There is no need to hire high-paying fire-watching teachers, which fundamentally eliminates brick-making and greatly increases production.
