Palmar de Bravo, Mexico (Completion 2016)
thyssenkrupp Industrial Solutions commissioned a turnkey 3,500 tpd cement production line. The new line was constructed alongside the cement production line that was set up by Polysius in 2006. The first line had already been prepared for the connection of the second line. The integration of the new line more than doubles the clinker capacity of the works.
Cemento de Bolivia
Cementos de Bolivia ordered a 3,000 tons per day kiln line, successfully commissioned in 2019. This was an EPC contract to the German-Spanish polysius-Imasa-Valoriza consortium. The contract included a QMR² 38/19 for raw grinding and a QMC² 45/23 for cement grinding.
After the shortest time, the plant was able to meet the project’s design parameters, fulfilling all process/technical guarantees.

polysius® booster mill
The polysius® booster mill in operation in an industrial pilot installation
In 2017 a pilot installation was commissioned in a grinding plant in Turkey. For two years, the mill operated in fly ash grinding, the results in product quality and high energy efficiency convinced to keep the mill. Since the second half of 2019, this mill upgrades an existing ball mill grinding circuit of the integrated cement production, achieving an increase in production capacity and also in cement quality.
Several trials were conducted with different cement types. This led to an increase of the CEM I 42.5 N cement production by some 20 percent, up to 56 from 45 tph. Furthermore, a higher compressive strength at nearly the same Blaine surface area indicates an additional potential for production increase by adjusting the cement quality. Second positive result was the significant quality improvement. By switching on the new mill, the compressive strength of the cement was able to meet the CEM I 52.5 R requirement, while maintaining the original production rate. The starting point was the CEM I 42.5 R at a rate of 38 tph.
Re-use and refurbishment of existing components allow a successful and efficient project execution
Ashaka Cement contracted thyssenkrupp Industrial Solutions to modernize a feed conveyor and spillage.
Parts of the old apron conveyor and spillage conveyor were removed and replaced with the new machine components. It was possible to retain the existing drives, the main and longitudinal beams.
Reduction of power consumption by 10 %
Cost savings through maintenance optimization by 20 %
