Optimize clinker production performance
Integrated online monitoring and optimized fuel management improves clinker production performance
Cement manufacturing is an energy intensive activity and the choice and mix of primary and alternative fuels affects both the environmental impact and economics of the process. Total energy cost can represent 65-75% of the variable costs in the process. To save energy, modern cement plants preheat the mix of raw materials before they enter the kiln. In addition, secondary burning points are installed using alternative fuels to reduce energy output.

Your challenge
The pyro-processing stage is generally known as the heart of the cement making process. It is the stage in which most of the operating costs in cement manufacturing appear and is also where most opportunities for process improvement exist. The main challenges at this stage in the clinker production are preventing blockages in the preheater, measuring the process accurately and maximizing production in this hot and rough environment.
Our solution
For the best outcome in the clinker production process, Endress+Hauser offer an integrated package that optimizes energy efficiency. The right combination of instrumentation (Cerabar S, Omnigrad S, Deltabar S, Solicap S/Soliwave M, Micropilot FMR57, Gammapilot M) makes all the difference. Also, our all-inclusive service portfolio helps to support you locally to secure the availability of your plant.
