Gas flow measurement in cement plants
A large portion of the total electrical energy consumed by a cement plant goes into fan power. Fans are also a key component when it comes to process control, whether it be raw mill gas flow or the control of the downcomer flow by ID fans. The most critical element, the gas flow itself, is rarely measured correctly.

Treating Waste Gases
The hot exit gas from the preheater enters the high temperature fan via a conditioning tower. All the waste gas from this fan is fed into the raw mill where it acts as the drying heat source. When the mill stops and the kiln opens, the gas, after its temperature is lowered and treated by the conditioning tower, enters the ESP.
