Watch the Video: Rockster impactor proving itself in recycling asphalt and demolition waste

A Rockster closed circuit impact crushing plant with a screening system and air blower, a newly introduced R1000S model, has been working at the Bauhof Deutschlandsberg waste management plant in Austria since the beginning of 2020, aiding in the production of recycled building materials.

According to Rockster, the processing capacity on the Bauhof site is 80,000 tons per year, which corresponds to a saved landfill volume of 55,000m³. With a recycling rate of 98%, the maximum "avoidance and recycling before landfill" is consistently implemented.

In addition to a trommel screen, excavators, loaders and road rollers, a rented crushing plant is also always in use at the plant, processing approximately 40,000 tons of debris, asphalt and concrete every year. At the end of 2019, Bauhof management decided to replace their rented crushing plant with Rockster's new R1000S closed-circuit impact crusher. 

In order to guarantee quality end-product in one workflow, three elements of a new plant were vital to their decision. It would need to include:

• A screening system for a precisely defined size of end-product
• A magnetic separator for removing iron and other metals
• An air blower for separating non-aggregates such as polystyrene, wood, plastic, paper and other materials.

Due to the compactness of the Rockster crusher, Bauhof says their contract crushing business can now be expanded. Well-known customers such as Granit Graz, Porr or Swietelsky, as well as private customers, have already rented the R1000S and were satisfied with both the ease of handling and the quality of material.
