Non-stop production of concrete in the Alps

Published by

A major challenge at the Obervermunt II of VIW – Vorarlberger Illwerke AG power plant project in Vorarlberg/Austria is the year-round just-in-time production of concrete at an altitude of 1700 m.

Mobile concrete mixing plants type LINEMIX® made by SBM are an ideal choice for these challenging sites. Two LINEMIX® 3000 CM 410 H plants are used in parallel in the Silvretta region to assure trouble-free and continuous production of concrete until October 2017. This is carried out by a twin-shaft mixer with a quality concrete mixing capacity of 130 m³ per hour depending on the required mixing time.

Trouble-free logistics

One of the key elements of the building activity is the underground hydroelectric power station. Transbeton GesmbH & Co.KG from Nüziders, has started mineral processing directly in front of the dam wall of Vermuntspeicher. The aggregates to produce concrete are processed from the excavated material on the site. Rock storage is carried out by a mobile high hopper with a storage capacity of 410 m³. To be able to assure a 24/7 operation throughout the year both the rock storage and the mixing plant are provided with a completely winterproof insulation.
