Power and low emissionsPublished 16/9, 2019 at 15:10
Swerock is one of Sweden's largest suppliers of building materials to 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 Swerock, the reuse and recycling of demolition waste is extremely important, contributing towards a resource efficient society.
For this very reason, Swerock looked at the Rockster R1000S, supplied by its Swedish sales partner Niklas Johansson of Biocare Svenska AB. “High throughput of this compact machine, perfect transport dimensions and excellent access for maintenance, have convinced my customers (Swerock) that the Rockster crusher is the right one for them,” says Niklas Johansson. Thus for a recycling company like Swerock, the environmental impact of the machine was an important purchasing criteria. The company sees itself as an environmental friendly service provider, wishing to recycle construction waste, thus attaching great importance to the ecological footprint of the Rockster R1000S impact crusher.
Thanks to the hydrostatic drive of the crusher, which ensures a constant crushing power, the diesel consumption per ton is noticeably reduced. Niklas Johannson explains: “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.” In addition, the crushers Volvo Tier4f engine, with AdBlue, ensures very low NOx emissions.
Swerock’s R1000S is mainly utilised for recycling of demolition debris, with concrete crushed to 0-70mm in order to be used again for under filling in construction projects. Recycling of used asphalt is another application for the Rockster crusher where a final grain size is usually set within 0-16mm. “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,” says Niklas Johansson.
