Betolar’s new innovative method for metallurgical processing of slags for metal extraction and green cement production has been tested at pilot scale with excellent results in collaboration with a Nordic partner. In metallurgical processing a significant amount of valuable metals remain in slags.
Pneumatic conveying systems for injecting solids against very high back pressures (sometimes up to ≅ 50 bar) are used particularly in special gasification systems, but also in other processes. The following text provides a general insight into the aspects to be considered in the system concept and design for such requirements and provides appropriate calculation approaches.
Simple, smart and reliable – these characteristics have enabled the BASIC series of VEGAPULS radar sensors to establish itself as the benchmark in level measurement technology since its market launch in 2020. Compact, attractively priced and technologically superior, the sensors are setting a clear trend in process automation.
For producers of cement and building materials, efficiency, sustainability, and worker health and safety are key to operational success and brand reputation. Packaging plays a crucial role in all three areas. To assess performance, CEPI Eurokraft commissioned lab tests comparing paper and woven polypropylene (WPP) cement sacks.
Aalborg Portland has awarded Christian Pfeiffer with the delivery and implementation of a new high-efficiency separator QDK-T 250-Z on an EPC basis, including civil works, as part of a modernization project for cement mills 8 and 9.
When I entered the cement industry 30 years ago, I couldn‘t have made a better choice. I was looking for a job that was technically diverse and offered plenty of contact with people from all over the world. The relatively small, yet fully international cement industry offered all of this perfectly. Unfortunately, we are now seeing many countries around the world revert to archaic reflexes.
The drumming sound of bulk material hitting the metal sides of a hopper, bin or silo during loading is the sweet sound of production. If the noise becomes muffled, it likely indicates that the vessel is filling up, or it could signal the presence of buildup on the inside walls or the discharge gate. Once coarse material adheres, the buildup is generally fast and dense, eventually resulting in downtime to remove.
The new “Eleven Decks” residential building in HafenCity Hamburg/Germany impresses with its striking architecture made of red exposed concrete. Balconies and loggias made of through-colored monolithic precast concrete elements set architectural accents. Cement from Heidelberg Materials played a central role in the realization of the sophisticated concrete elements.
A large-scale test has shown that ETICS waste with HBCD-containing EPS can be materially and energetically recovered under controlled conditions without negative effects on emissions, operation and clinker quality - a possible building block for a broader raw materials strategy.
For some time now, manufacturers’ associations have been pointing out that the phasing out of coal-fired power generation could lead to a shortfall in the supply of gypsum raw materials. The potential of gypsum recycling is currently insufficient and cannot be fully exploited due to the lack of a legal basis. Will there be a shortage of gypsum in Germany if coal-fired power plants are no longer connected to the grid? “Yes,” says a BGR study, which has now been presented to representatives from industry,
