Milling and mixing rotors for cold recyclers and soil stabilizers

DURAFORCE - A single rotor catering to all requirements

Challenging operating conditions such as the powerful cold recy-cling, granulation or stabilization of coarse-grained soils make ex-treme demands on the cutting tools. This calls for perfectly matched components designed to meet the highest performance requirements. They can be relied on to provide high milling and mixing performance while ensuring maximum resistance and durability at the same time.

The original WIRTGEN DURAFORCE milling and mixing rotor im-presses with extreme wear resistance, impact strength and frac-ture strength for all applications in soil stabilization and cold recycling: a single rotor catering to all requirements.

High-performance soil stabilization

Soil stabilization, which is in use around the globe, represents the ideal solution for converting subsoils of insufficient bearing capacity into soils suitable for placing and compacting. In the process, a wide variety of different types of soils need to be processed which may be highly cohesive, abrasive or even interspersed with coarse-grained rock.

Requirements on the milling and mixing rotor:
  • Effective splitting and crushing of the soil to optimize binder effectiveness
  • Uniform distribution and homogeneous mixing of binders and, where appropriate, water to produce a mixture of high strength
  • Maximum cutting performance even in tough, hard soil to ensure high productivity and low fuel consumption
  • High fracture strength when operating in soils interspersed with coarse-grained rock to ensure extended uptimes
  • High wear resistance in abrasive, cohesive soils to ensure maximum economic efficiency

The tried-and-tested WIRTGEN DURAFORCE milling and mixing rotor meets every challenge in soil stabilization and is the ideal candidate to convert even the most difficult soils into construction materials of superior quality.

Environmentally friendly cold recycling

Cold recycling and granulation are also internationally established construction processes. Distressed asphalt pavements comprising the most diverse types of rock and the underlying gravel layer are milled, usually mixed with added binders to produce a homogeneous material and then placed again in an in-situ process.

Requirements on the milling and mixing rotor:
  • Steady milling process to prevent oversized particles and to ensure high-quality results
  • High milling performance and low wear even in hard, abrasive material to ensure high economic efficiency
  • Compliance with the specified grading curve to ensure the permanent structural integrity of the new base layer
  • Homogeneous mixing of the binders to ensure high adhesion (bonding strength) between the individual particles and thus maximum bearing capacity
