Wirtgen Launch New Rock Crusher

The WRC 240(i) from Wirtgen expands their portfolio of wheeled soil stabilisers designed especially for the processing of stony ground. In addition to the crushing of rocks and stones with an edge length of up to 300 mm and a strength of up to 200 MPa, the machine can add cement and water in the same pass, for instance in the preparation of base layers. Here, the cement is pre-spread with a binding agent spreader and the water required is sprayed into the mixing chamber of the Rock Crusher via the machine’s Varioinjection bar.

The machine can also be used for soil stabilisation. For this application, the pre-spread binding agents such as lime or cement are mixed into the existing soil with insufficient bearing capacity, transform it in-situ into a high-grade construction material and deposit it evenly behind the machine. The main task of the WRC is the granulation and mixing of a variety of soils, courses and layers to produce a homogeneous final product in a continuous process. In contrast to the removal and replacement of material, the processes here are characterised by shorter construction times, conservation of resources and lower CO₂ emissions, says the company.
