Schwenk, Allmendingen (Germany)

Did you know: The world’s largest rotary drum dryer for sludge handling helps one of Europe’s leading cement manufacturers to produce dried municipal sludge from kiln exhaust heat as a sustainable fuel source while significantly reducing the plant’s raw fuel consumption and CO2 emissions.

Energy efficiency. For cement manufacturers, it can make a world of difference. Take, for example, one of Germany’s largest cement producers, who approached us with an innovative idea. They wanted to turn municipal sludge into a sustainable fuel source using recycled exhaust gas heat to dry the product.

Our solution:

The world’s largest rotary drum dryer for sludge drying, 4.6 m in diameter and 17 m in length, achieving dry solids content of 90% using only exhaust gas from the cement kiln as a heat source.

Results:

Eliminated the need for costly heat exchangers, reduced annual raw fuel consumption by about 20,000 tons/year and CO2 emissions by nearly 30,000 tons annually.
