Rotary kiln is widely used to calcine cement in China's cement production industry. As we all know, the cement rotary kiln is an upgraded version of the traditional shaft kiln. Compared with the shaft kiln, what are the advantages and disadvantages of the rotary kiln for cement production?

It can reduce air pollution. China's main industrial fuel is coal, which will produce some waste gas pollution. Cement rotary kiln products have been developing new fuel technologies, such as the use of natural gas, which will reduce air pollution.

Save fuel. The cement rotary kiln has a high utilization rate of fuel, while the shaft kiln is still coal-fired, and the utilization rate of fuel is relatively low.

The final product, that is, cement stone has better powder quality and whiter color. The vertical kiln is much worse than that.

The production capacity of the kiln is greatly improved. However, the shaft kiln is intermittently discharging, so the production efficiency is not high enough.

Of course, the cost of cement rotary kiln as an upgrade version is higher, so the price is higher.
