Swerock is one of Sweden’s largest suppliers of building materials and services for the construction and civil engineering industry. The company has approximately 950 employees and is part of the Peab Group, which is the third largest construction company in the Nordic region, with approximately 14,500 employees in Sweden, Norway and Finland combined. For a company like Swerock, value-adding reuse and recycling of demolition waste is extremely important for a contribution toward a resource-efficient society. This is exactly why they invest in advanced machinery like Rockster.
Mobile impact crusher R1000S for recycling projects
Rockster’s Swedish sales partner Niklas Johansson of Biocare Svenska AB is responsible for introducing Rockster mobile crushers to Andreas Pettersson, the area manager of Swerock Recycling. He is convinced of the benefits from Rockster’s Impact Crusher R1000S.
“High throughput of this compact machine, perfect transport dimensions and excellent access for maintenance have convinced my customers that the Rockster crusher is the right one for them,” said Johansson.
Thanks to the hydraulically lowerable screen box, the swiveling catwalk and the swivel-up doors, service work, maintenance and the replacement of screen meshes can be carried out quickly and easily.
For a recycling company like Swerock, environmental impact of the machine is an important purchasing criterion. Since the company sees itself as an environmentally friendly service provider and wants to contribute to the recycling of construction waste for the protection of raw materials and the reduction of waste, they also attach great importance to the ecological footprint of the Rockster R1000S impact crusher. Thanks to the hydrostatic drive, which ensures a constant crushing power, the diesel consumption per ton is noticeably reduced.
Johannson explained, “With Rockster’s hydrostatic system, the diesel engine always stays in the optimal RPM range; only the hydraulic pump adapts to the crusher’s power requirements, which results in lower fuel consumption per ton of final material.” Additionally, the Volvo Tier4 final engine, with AdBlue, ensures very low NOx emissions.
Processing of asphalt and concrete
The R1000S at Swerock is mainly utilized for recycling of demolition debris. Concrete is crushed to 0 – 70 mm in order to be used again for underfilling in construction. Recycling of used asphalt is another application for Rockster crusher, where a final grain size is usually set within 0 – 16 mm.
“Thanks to the screening system, the final grain can be precisely defined and no oversize material is produced. This way we can achieve the maximum added value in our recycling process,” said Johansson.
