Steinag Rozloch AG

The Rüti quarry has a 100-metre chute, in which fine particles are produced through friction. They do not meet the required standard for production. With the new system, these components are refined into high-quality concrete aggregate components.

Client/developer: Steinag Rozloch AG

Place: Stansstad

Project: processing plant

Year of construction: 2013

As general contractor, Frei Fördertechnik AG took on the implementation of the entire plant. The complete steel construction and the silo battery were placed on a foundation slab. The preparatory work for the foundations was extremely elaborate due to the rocky subsoil.

Special features

  • Jetting chute for cleaning and vertical crusher for the standardised cubing of the material as the heart of the system
  • Steep build-up of the material
  • Option for double assignment of many silos
  • Compact design of the system due to lack of space
