The operating principle of the slurry mixer

The modern WM 1000 - here's how it works

  1. High-performance water-cement slurry mixer

    Powerful slurry mixer for the production of a homogeneous water-cement mixture.

  2. Water tank including filling pump

    Extra-large water tank for extended productive periods.

  3. Cement container with filling level indicator

    Extra-large cement storage container for extended productive periods.

  4. Feeding, discharge and weighing augers

    Electronically controlled feeding, discharge and weighing augers for precise weighing and metering of the cement into the slurry mixer.

  5. Pressurized slurry hose to the recycler

    Flexible hose supplying slurry to the mixing chamber of the recycler coupled to the mixer.

  6. Hydraulic steering

    Hydraulic steering system allowing independent control at the front and rear for precise steering behaviour.

  7. Diesel engine

    Fuel-efficient, environmentally friendly diesel engine.

  8. Highly precise slurry addition

    Microprocessor-controlled addition of water and cement into the slurry mixer for precise compliance with mixing formulations.

Wind erosion hazard precluded

Using machines to pre-spread dry cement on a large scale in cold recycling causes binder drifts in windy conditions. This not only wastes valuable construction materials but also results in dust polluting the environment and posing a danger to passing traffic. The mobile WM 1000 slurry mixer enables construction companies to eliminate these problems in their entirety. Cement and water are premixed in the closed system in a microprocessor-controlled process. The resulting slurry is then pumped into the recycler’s mixing chamber via a flexible hose. The cement is added in a dustless process, in precisely metered quantities and in accordance with the recycler’s advance speed. The WM 1000 is coupled to and pushed by the recycler during the recycling operation. The unit is simply hooked to a standard truck for transport to the construction site.

Great ease of operation enables high-quality work results.

A whole range of practical advantages

  • The cement can be added regardless of wind and weather conditions as it is contained within the closed system.
  • Cement and water are supplied to the recycler via the WM 1000 without requiring additional tanker trucks.
  • The traffic can always be guided past the moving roadworks on adjacent traffic lanes. These advantages may possibly be limited when pre-spreading dry cement.
  • Microprocessors continuously measure the cement quantity, thus ensuring accurate metering.
  • The liquid water-cement slurry is ideal for mixing into construction materials.
  • Processing the cement slurry in a closed system poses a hazard neither to passing traffic nor to residential areas, nature reserves or industrial estates specifying strict emission standards.
  • The large storage containers installed in the WM 1000 allow continuous operation, thus enabling higher area performance rates than separate, low-capacity spreaders.
  • The large filling capacities enable delivery trucks to be fully emptied in a single step without incurring additional waiting times on site.
