Crush, Combine, Unfold Street Base in One Move with Wirtgen’s New WRC 240i Rock Crusher

Wirtgen’s new WRC 240i Rock Crusher can grind up stony floor and add cement and water in the identical cross for such duties as laying highway base.

The WRC is a part of Wirtgen’s wheeled soil stabilizer lineup. Together with stone from the jobsite, the crusher can deal with the crushing, processing and homogenization of onerous core, concrete fragments and cobblestones, the corporate says.

“The principle process of the WRC is the granulation and mixing of a number of soils, programs and layers to supply a homogeneous last product in a steady course of,” Wirtgen says. “Versus the removing and substitute of fabric, the processes listed here are characterised by shorter development instances, conservation of assets and decrease CO2 emissions.”

Operators can set the specified grain dimension of the crushed materials with the WRC’s vertically stacked, hydraulically adjustable classifying screens. The Rock Crusher can produce 600 tons an hour of homogenous combine with its working width of 91 inches and 10-inch working depth.

For stabilizing soil, pre-spread binding brokers similar to lime or cement are blended into the prevailing soil the place it’s reworked into high-grade development materials and deposited evenly behind the machine, in accordance with Wirtgen.

Options on the WRC 240i embody:

• The crushing and mixing rotor’s toolholders are developed particularly for crushing purposes on stony floor. The instruments are fitted with carbide slicing edges, and the holder bases are protected by wear-resistant, high-tensile metal.
• The rotor housing and full mixing chamber are lined with replaceable, abrasion-resistant sporting plates constructed from high-tensile metal for longer service life and total stability of the housing.
• A number of setting choices can be found to realize desired grain dimension and constant, uniform distribution. That features 9 rotor speeds, a variable crushing stage, exchangeable screens with a spread of clear mesh sizes and adjustable distance from the rotor, adjustable rotor plate strain, and the machine advance fee.
• The satellite-based AutoTrac system mechanically steers the WRC “precisely inside tolerances of some centimeters,” Wirtgen says.
• The Wirtgen Efficiency Tracker (WPT) displays and data the Rock Crusher’s location and dealing information for job evaluation and documentation.
