Rockster at work in Austria
"Greater flexibility, higher performance, faster implementation of large projects," is how Ferdinand Polixmair described the challenges of the increasingly fast-moving mineral processing business.
"We can handle up to four major projects in parallel,” explained company owner Ferdinand Polixmair, whose company in Gmunden in upper Austdria has eight employees. “We have the team and the machines available. Moreover, we have no regional restrictions, we cover the whole of Austria."
Polixmair had two of his three mobile crushing plants from Rockster. The company Kormann5074 Rockster Recycler is based in Ennsdorf bei Enns, Austria. It specialises in the design and production of mobile crushing and screening systems for profitable recycling of asphalt, concrete and demolition rubble as well as natural stone.
"We have been working with Rockster crushers for about two and half years. The two R900 impact crushers are very quick and easy to transport on our own truck, making us flexible and quick in setting up," said Polixmair.
Since the company doesn’t want to reject projects, the family decided to purchase an even bigger Rockster crusher. During the four-day Mawev construction equipment exhibition in Graz in March 2015, they checked out the R1100 series of the Austrian crusher manufacturer. They then decided some months later to buy an R1100D. It has a significantly larger feed hopper, a 20mm-wider inlet opening and a higher throughput compared to the R900.
"To avoid complicated special permits for transport we were looking for a plant of less than 40tonnes, but still providing good performance. This goal was definitely achieved with the R1100D. With use of a screen box and return belt we crush on average 200tonnes of asphalt per hour to 0-3 mm and about 150tonnes of concrete to 0-32mm. The magnetic separator works properly and the final grain is of excellent quality," explained Polixmair.
A big current project is the reconstruction of the highway A10 in Salzburg, where 100,000tonnes of highway concrete needs to be recycled. Polixmair got the contract and is currently preparing 5,000tonnes of concrete per week, producing high quality final material with 0-32mm, which is used for stabilisation and fillings in road construction. The project will continue until this summer.
