Recycling of Demolition Debris & Asphalt with Impactor R900

All-in-one Solutions

Polixmair offers "everything from a single source" - the Rockster impactor R900 is an important part of this business model

In the fall of 2013, the contractors Mr. Polixmair Junior & Senior, decided to buy the Rockster Impact Crusher R900 including screenbox and return belt. A main argument for Rockster were the optimal transport dimensions and a weight of only 28.5 tons, including screenbox and return belt, which also don't have to be dismantled for transport. 

R900 Polixmair"We have our customers all over Austria and plan our tours very precisely. Complicated transport handling and bureaucracy limit our flexibility and our conversion rate for each project . Therefore it is very important for us to keep the logistics as simple as possible. The R900 fits to our own trailer perfectly, just as we imagined it, " says Ferdinand Polixmair. Moreover with the legal permission, the machine is ready for use on any site immediately. 

90,000 Tons of Construction Waste on "Semmelrock" Construction Site

Beton brechen R900 - Crushing Concrete R900Recent big project is the demolition work and waste recycling of a huge Semmelrock plant that was closed in Traismauer (Lower Austria). From the preparation (chiseling work, scaling, etc.) to the final material - separated from iron - Polixmair offers everything from one source.
Five major road trains with iron have already been sorted out with the iron magnetic separator of the R900 crusher. The project is planned on 4 periods each 5 weeks (including preparation time), with each more than 20,000 tons of construction waste to be processed. Especially floor slabs and paving stones with a length of about 300-400mm are crushed, the majority of the final material has 0-16mm in diameter and will be picked up and sold by the gravel company Weber/Austria. 

The Second Focus - Asphalt Recycling

Asphalt brechen R900 - Asphalt Concrete R900In addition to the recycling of concrete and demolition debris Polixmair is specialist in asphalt recycling and therefore he only uses the Rockster R900 impactor. His clients are mainly asphalt mixing plants. He crushes old asphalt/RAP with lengths of up to 1000mm with the use of screenbox and return belt to a final grain size of 0-16mm. This recycled asphalt is used in full for the new production of asphalt, that saves the mixer a lot of money for bitumen and also protects the environment.

Hydraulic Concept Simplifies Individualization 

"Especially when it comes to asphalt recycling, it is important for us to produce high-quality final grain and meet all our clients' requirements. Due to the hydraulic concept of Rockster machines, the speed of the crusher, the conveyors, the screen,... everything can be continuously adjusted, so it is simple to adapt perfectly to every material and grading curve without much effort. The crusher is also very easy to operate and maintenance work on the machine can be done quickly and effectively," concludes Mr. Polixmair.
