Level and pressure instrumentation for the cement industry

To produce cement, the raw meal is burned to clinker in a long rotary kiln. After leaving the rotary kiln, the clinker has a temperature of up to +1300 °C and must be cooled down to a temperature of about +200 °C for further storage. To achieve this, the clinker bed is cooled with a continuous stream of air.

Advanced Process Control () for cement .

The rotary cement kiln process is intrinsically unstable, there are long time delays and large perturbations acting on it. The control problem consists of maintaining a given temperature profile along the kiln plus obtaining good burning conditions.VFD in Cement Industry - Variable Speed DrivesIn cement plants, VFDs provide controlled torque and speed to the kiln, which increases the life of the mechanical system, and reduces maintenance and operating costs. The VFDs also provide feedback signals, which improve cement kiln process control.
