Bauer goes big on separation

2017 10 mat mischanlagentechnik a new dimension in separation technology (1) (groß)

Work on a large diameter tunnelling project has proved the capability of one of Bauer’s subsidiaries, according to the company.

Bauer has said that Mat Mischanlagentechnik has successfully developed the technology used for separation plants on microtunnelling projects for major projects through its work on the Eppenbrg Tunnel in Switzerland.

Mat developed the BE-2550 to manage slurry produced by tunnelling work on the 2.6km, 12.75m diameter tunnel. The separation plant was put into full action in August when the tunnel mode was switched from hard rock to slurry mode for the last 700m of the bore.

The BE-2550 is made up of six standalone BE-425-60 plants connected together to offer 2,400m3 per hour of slurry processing. The system uses screens and hydrocyclones to separate bentonite slurry from the excavated soil to allow the bentonite to be reused.
