Industrial Fan solutions for Cement industry applications
In the cement industry coal mill fans are used to supply the required air for burning coal and remove the exhaust gases produced after burning. This is where the coal is grinded into the proper size to be fed into the burner. The coal mill fan moves the coal into the grinder. Thus these fans help ineffective burning of coal inside the mill.

Preheat Towers
Preheat Towers. Kiln preheater towers provide heat transfer from hot gases to kiln feed material. The counterflow of gases and material takes place in cyclones, referred to as stages, in the preheat tower. As material flows from the top to bottom of the tower, it is exposed to increasingly higher temperatures as it is prepared to enter the kiln.
