Rotary kiln is a large-scale ore calcination equipment that can be used to calcinate petroleum coke, magnesium metal, rhombite, coal gangue, limestone and other ores. It needs to rely on a large amount of coal to calcinate to complete the work. It consumes a lot of energy during operation, so how to reduce the energy consumption of rotary kiln?

1. Transform the structure of the rotary kiln and configure an automatic control system

The traditional rotary kiln control system adopts conventional instruments, and the control level is relatively backward. It is inevitable that there will be a waste of energy, and the feed is not particularly stable, which will cause a waste of resources. Therefore, the internal structure of the rotary kiln needs to be optimized and improved, and an intelligent automatic control system is configured. The system can automatically adjust the amount of raw materials entering the kiln and the fuel flow rate, and the feed is more stable and uniform, which provides strong conditions for normal production and operation, and the effect of energy saving and consumption reduction is very obvious.

2. Reduce the loss of heat energy during the cooling of clinker

The material calcined by the rotary kiln needs to be cooled and processed by a cooling machine. In this process, it is easy to cause heat loss. Therefore, it is recommended that the processing plant use a single-cylinder cooling machine, and the kiln head should be equipped with a corresponding sealing device to prevent short circuit of cold air.

3. Reduce the heat loss of the carcass of the rotary kiln

The rotary kiln mainly emits heat through the carcass, and its heat consumption accounts for about 15% of the heat consumption of clinker.In order to reduce the heat dissipation of the carcass, refractory bricks need to be built in the kiln to achieve the purpose of reducing the surface temperature of the cylinder, and a layer of refractory coating can also be applied to the surface of the carcass to achieve the purpose of reducing radiation.

4. Strengthen the training of staff

If the operator's operation is not proficient enough, it will lead to a lot of unnecessary energy loss during the operation of the rotary kiln. Therefore, the processing plant needs to conduct technical training for the operation and monitoring personnel of the rotary kiln to ensure that the operator is fully proficient in the operation process before he can take the job, so as to more effectively reduce the heat loss of kiln ash, the heat loss of exhaust gas, and the heat loss of evaporated water.

Due to the different production environments and production conditions of each processing plant, reducing the energy consumption of rotary kilns requires specific analysis. To learn more about effective ways to reduce the energy consumption of rotary kilns, you also need to consult relevant experts.Xingkuang Group has focused on the production of high-performance and high-quality rotary kiln equipment for more than 30 years.
