The DKXS mixer is designed to ensure reliable and homogenous concrete mixtures

BHS-Sonthofen is supplying the DKXS 4.50 twin-shaft concrete batch mixer to support the massive Grand Paris Express rapid transit project.

Unibéton, a French subsidiary of the HeidelbergCement Group, is producing specific ready-mix concrete for the project.

In the Issy-les-Moulineaux suburban area of Paris, Unibéton is using new concrete recipes which require longer mixing times. In order to ensure reliable and homogenous mixtures batch per batch, the Unibéton management team decided to replace one planetary mixer with the more powerful DKXS 4.50 twin-shaft batch mixer from BHS-Sonthofen. For the first time in France, the mixer was installed with frequency convertors to enhance operations.

Grand Paris Express is claimed to be the largest public transportation and infrastructure project in Europe, comprising four new transit lines and the extension of further three existing lines.
