Upgrade of the clinker burning line at Rudniki Cement Plant

In 2019­2020, the Rudniki Cement Plant, part of the international CEMEX group, modernized its kiln lines by switching from long dry kilns to a new process with a short kiln and an external preheater. With the purpose of drastically reducing production costs while maintaining the volume. The financial success of the project is largely related to the effective use of legacy equipment in the new line, combined with top­notch, efficient dry process technology. The company assured its target KPI values: clinker production cost was down by 26%, heat energy consumption ­ by 21%, CO2 emissions ­ by 17%. Heat substitution rate of substituted municipal solid waste reached 80%. The new line has considerable future upside potential to help further improve the production process.
