Apr 29, 2016 CQGI has had capacity of designing and manufacturing all centrifugal fans with complete equipment for 2000t d - 12000t d new dry-process cement clinker calcination system and cement grinding system. The fans include kiln inlet exhaust fan, high temperature fan, kiln outlet exhaust fan, raw mill circulating fan, coal dust fan, grate cooler.
The air volume can be controlled by adjusting the power of the circulating fan of the mill or the opening of the exhaust fan at the kiln tail. If the air volume is too large, the pressure difference in the mill and the current of the main motor will decrease, the thickness of the material layer will become thin, and the vibration degree of the mill body will become strong.
