Do you want to increase sustainability by using existing materials while reducing costs associated with trucking?

WIRTGEN’s new WRC 240i rock crusher breaks course rocks in situ, such as pavement layers and stony soils, and produces a homogenous mix in a continuous process that shortens construction times, conserves resources, and lowers CO2 emissions.

With a working width of 7 feet, 10 inches and a working depth of 20.1 inches, the WRC 240i has an output of up to 600 tons per hour. In addition to crushing rock and stones with an edge length of up to 11.8 inches and a compressive strength of up to 200 MPa, the machine can add cement and water in the same pass. It can also be used for soil stabilization, transforming undesirable soils into a high-grade construction material and depositing it evenly behind the machine.

The WRC 240i offers several setting options that enable the achievement of the desired grain size and consistent uniform distribution in a wide range of applications. Nine rotor speeds, a variable crushing stage, exchangeable screens with a range of clear mesh sizes and adjustable distance from the rotor, adjustable rotor plate pressure, and the machine advance rate enable the configuration of the machine to meet the demands of actual site conditions and the desired application.

Newly developed crushing and mixing rotor

The rugged and resilient crushing and mixing rotor with toolholders developed especially for crushing applications enables optimal results when working in stony ground. The tools are fitted with large, impact-resistant carbide cutting edges, and the holder bases are protected by wear-resistant protective elements made from high-tensile steel. This ensures high machine utilization rates and process reliability in demanding applications. Robust edge protectors reduce wear on the edge ring segment of the rotor, which is driven via a transmission developed especially for the WRC that enables high rotor speeds.

For long-term resistance to the stress encountered when crushing rocks, the rotor housing is lined with abrasion-resistant wearing plates made from tough high-tensile steel. These guarantee a longer service life and increase the overall stability of the housing. The entire mixing chamber is lined with these wearing plates, which can be individually replaced if and when required.

By enabling precise, automatic steering, the satellite-based AutoTrac system helps the WRC to achieve greater process efficiency and a high degree of environmental compatibility. It steers the machine accurately within tolerances of a few centimeters on the basis of a previously calculated reference strip and a specified overlap of adjacent strips for consistent utilization of the machine’s ideal working width. The WIRTGEN PERFORMANCE TRACKER registers all relevant location-specific working parameters to provide a comprehensive database for the analysis and documentation of the construction site.
