Ten BHS mixers for China's high-profile Pinglu Canal project

January 2024
China is a country of superlatives, not least in terms of population: With more than a billion people and huge agricultural areas, securing a continuous supply of water for the nation has become paramount. Reservoirs and dams help store water and regulate its distribution, especially in times of drought or water rationing. Over the past few decades, China has therefore embarked on a series of major construction projects. One of the currently most important projects is the Pinglu Canal Project, for which BHS-Sonthofen has supplied eight large BHS twin-shaft batch mixers of type DKX 7.00 and two additional DKX 4.00.
