Clinker

Thermal efficiency

Cement kilns have become highly energy efficient as older plants are being upgraded or replaced.The energy intensity of cement manufacturing is influenced by regional characteristics such as raw material moisture content and burnability, fuel types, plant size distribution, and cement standards. Because of these variables, especially a higher thermal substitution rate, CEMBUREAU has projected an energy consumption of 3.300 MJ/tonne clinker by .

Fuel substitution

Fossil fuels have been substituted with pre-processed waste, including biomass, of which mineral content also partially replaces primary raw materials. This increased use of alternative fuels and materials is aimed at reducing CO2 emissions linked to our thermal energy needs as well as the use of primary natural resources. Waste streams that are non-recyclable through conventional processes (such as used tyres, certain types of plastics, and chemicals) are co-processed in cement kilns in plants across Europe. By , the average substitution rate could be as high as 60%. In some countries, it is already today more than 90%. This makes the European cement industry the global frontrunner in the use of alternative fuels and materials.

Clinker substitution and novel clinkers

The effort in reducing the amount of clinker in cement is progressing well and the clinker to cement ratio has been reduced to 76,4%. The uncertain sustainable availability of clinker substitutes is the main constraint. CEMBUREAU has projected the clinker to cement ratio at 70% by .

Reduce power and increase production Either on greenfield or Brownfield projects

The FCB Horomill® is renowned for reducing energy consumption in raw meal, cement or slag grinding applications. It also boosts production capacity, by offering an increased cement/clinker ratio relying on the ability to process a wide spectrum of materials:

• Coarse to very fine product
• Dry to highly moist material
• Soft to very abrasive compounds

Our modular grinding system, FCB FLAG' station, equipped with FCB Horomill® technology, features pre-assembled and pre-wired modules for a fast unit set-up. This allows for an even competitive, simple and rapid solution to boost production capacity of existing plants.
