Austrian companies BAG Klöch Aufbereitungstechnik and Staber Holding have enjoyed a good business relationship for more than 20 years.
So when it came to investing in a new screen to produce aggregates for its diverse customer base, Staber contacted BAG.
Following a highly successful demonstration, a new QE241 scalper/screen from Sandvik is now making valuable products from primary and secondary resources.
A recent project the company has been involved in is the Tauern motorway which has been supplied materials from Staber’s Drau Valley sand and gravel pit in Pöllan, which became operational in 1998. Joint managing directors Hannes and Michael Staber operate the 16-acre (6.5 hectare) site to provide materials for the earthmoving side of the business.
To improve business operations, the brothers realised they needed a compact screen, but with a large screening area. The screen would be used in their own gravel pit, as well as on customer construction sites dealing with excavated materials and, when applicable, for recycling construction materials.
As on-site and site-to-site mobility were paramount, the screening plant needed to fit onto one of the company’s trailers, and be easily transportable to customers’ construction sites. This year, Staber settled on a new mobile Sandvik QE241 mobile scalper.
Sandvik developed the product based on customer feedback. Targeted at the European market, it combines performance, flexibility of use and transportability with quick set-up. It also benefits from the long history of Sandvik’s mobile scalping developments, and includes characteristics of the larger models in the series, such as a two-way split configuration and sequential start-up.
Since being acquired in April, the QE241 has been in continual use at the gravel pit on a single-shift operation. In addition to its quick set-up and changeover times, the throughput, which has been measured as between 120 and 300 t/hr depending on the material, has met with Staber’s approval.
Its flexibility has meant that the QE241 has also been able to produce materials from other sources for local construction companies, as well as for the asphalt and concrete industry.
