The R700S impact crusher at work processing 5,500 tonnes of asphalt and concrete in Beijing

In what is claimed as a first, a Rockster Recycler R700S tracked impact crusher was used by specialist contractor Beijing Yu Long Environment Protection during the renewal of a road in the Chinese capital of Beijing. Like many of its Western counterparts, the local government bodies have laid down strict requirements concerning the use of mobile crushers within the city boundaries, and this is said to be the first time that recycled asphalt and concrete were crushed directly on a site and immediately reused in the city.

The R700S produced a constant output in excess of 100 tonnes per hour to a size of 0/32 mm and also showed low fuel consumption. It was also fitted with dust suppression on the main belt, resulting in minimal emissions of either dust or exhaust gases during the machine’s operation.

Mr Wang, the project manager at Beijing City Road and Bridge Construction Group, said: "It is very important for us to recycle construction waste so we can protect the environment and save natural resources." Estimates indicate that 40 million tonnes of construction and demolition waste is generated within Beijing every year, with some 90% of this being reusable, suggesting a major opportunity for efficient recycling operations.
