Global Cement speaks with Klaus Holz, the Head of the newly-formed Business Segment Cement at the major global lubricant supplier Fuchs Petrolub SE.

If the cement industry were a country, it would be the third largest emitter in the world, behind China and the US. It contributes more CO2 than aviation fuel (2.5%) and is not far behind the global agriculture business (12%).

Unless you live in the jungle, every hour of every day you are surrounded by something that’s made with cement. Roads, tunnels, offices, schools, hospitals, bridges – cement is everywhere. As the need for cement grows, so does the focus on health and safety issues associated with its production.

The calcination of limestone to make burnt lime takes place at 900-1200°C, which requires a lot of thermal energy. For this reason, lime producers and kiln manufacturers constantly seek more efficient processes. Köhler Kalk in Northern Hesse, Germany, recently commissioned a new lime kiln from Italy’s QualiCal. Thanks to the rotary lobe compressors made by AERZEN, the plant is one of the most efficient solutions in its field.

Xuan Thanh Cement, which boasts one of the largest cement lines in the world, ordered a second high-capacity FLSmidth Cross-Bar Cooler for its newest cement production line (line three) earlier in 2019. The latest generation of the Cross-Bar Cooler operates successfully in more than 130 cement plants around the world, including on Xuan Thanh’s second line.
