The preheater is a Holcim patented two-string hybrid tower that consists of four quad cyclone stages and a final dual cyclone in the fifth stage. It's ...
The material then moves through the preheater tower, starting at the top and moving to the bottom. The pre-heater tower helps make the kiln process more efficient by adding heat generated from the plant to the raw materials, starting the chemical reaction. Doing this makes the cement process more efficient.
The cyclone preheater can take full advantage of heat in the cement rotary kiln, reduce the heat consumption of clinker production, and reduce the room occupied. To meet ideal effect, …
