​The energy situation of our country is quite severe.There is a big difference between present situation of building materials industry and national requirement of sustainable development in our country.

Grate cooler is an important part in the pre-calciner kiln system. It plays a key role in the stable operation of the kiln. And its basic functions are described in detail below.

Cement mill is a kind of building materials equipment, which has the characteristics of strong adaptability to materials, large crushing ratio, strong continuous production capacity, easy to adjust the fineness of grinding products, etc., and plays an irreplaceable role in the cement production process. In the working process, some failures are unavoidable.

At present, there are a lot of cement production lines need to use high moisture raw materials, in this case, need to use a large number of external heat sources to dry the material, at this time, hot air furnace has become a most conventional choice.

The commonly used powder separator in the closed-circuit cement grinding system includes O-Sepa powder separator, rotor powder separator and combined powder separator.

At present, the domestic high-efficiency powder separator mainly includes O-Sepa powder separator, combined powder separator, coal mill dynamic powder separator, K type powder separator, etc. However, due to the improper control of parameters in use, it is difficult for the high-efficiency powder separator to achieve the ideal effect.
