Dry building materials

Creating top homogeneity with a gentle touch

Generating homogeneous mixtures with a gentle touch

When mixing dry building materials, maximum homogeneity is a key criterion. At the same time, the mixing tools must not damage sensitive particles in the mixture. With the dry powder batch mixer (type DMX), you are on the safe side when processing dry mixtures: The system was specially developed to meet the particular requirements of mixing dry mortar and other dry construction materials. The DMX combines the advantages of the three-dimensional mixing principle with innovative complete material discharge.

Benefits at a glance:

  • Superior twin-shaft mixing technology
  • High machine uptime
  • Gentle processing of the input material
  • Compact design and residue-free discharge
  • Low operating costs and high energy efficiency

The dry powder batch mixer (DMX) for the production of dry material mixtures

Twin-shaft mixing technology is suitable for all formulas and offers a wide range of benefits. The mixing procedure has a significant effect on the quality of the mixture produced and the economic efficiency of the production process. Watch the video to learn more about the use of the dry powder batch mixer (DMX) at the dry-mortar plant of Rethmisch GmbH.

Innovative approach delivers superior results

Innovative approach delivers superior results

DMX is based on the proven principle of twin-shaft mixing technology: Thanks to its excellent mixing properties, it is already being used successfully in a large number of applications in the dry material sector. The sophisticated mixing mechanism with its directional three-dimensional movement is highly effective, delivering improved mixing results at comparably low speeds. Grain structures of sensitive components of the formulation, such as perlites, polystyrene or expanded concrete, are completely retained due to the lower rotational speed.

Two large, tightly sealing discharge flaps enable optimum complete discharge to facilitate frequent product changes. The “Monogate” version with rotary gate discharge can be used for the consistent production of mass products. The smooth mixing mechanism reduces material build-up to a minimum. Depending on the application, linings in different materials, special plastic blades, various monitoring systems and a wide range of accessories are available.

The “sand maker”

We offer the ideal crushing technology to obtain the sand required for dry mortar production. The rotor impact mill (type RPM) is perfectly suited for producing high-quality, cubical crushed sand. The produced grading curve remains constant over the entire service life of the tools. Even off-spec grain sizes < 4 millimeters or return material are processed efficiently.

Benefits at a glance:

  • Rotor impact mill based on proven VSI technology
  • Constant grading curves over the entire service life of the tools
  • Targeted crushing level and cubic crushed sands
  • Low maintenance requirements

Success stories

BHS mixer with 28,000 liter capacity for mine backfilling in India

February 2024
An exciting event has taken place in the world of mining: A gigantic BHS twin-shaft mixer of type DKXC with a filling capacity of 28,000 liters has been successfully integrated into a mine backfilling plant in India. The size of this mixer is not only impressive, but also makes it a real eye-catcher in the plant.

National Museum of China displays sample of RCC mixed with BHS technology

February 2024
It is the largest sample of Roller-Compacted Concrete (RCC) in the world! And it is the result of a big project. The Dagu Hydro Dam is located 3,700 meters above sea level, making it the most elevated site ever for employing BHS twin-shaft batch mixers. A core sample of the dam was extracted in 2021. Due of its size and excellent quality, the National Museum of China chose to include it in its collection for public display in 2023.

Ten BHS mixers for China's high-profile Pinglu Canal project

January 2024
China is a country of superlatives, not least in terms of population: With more than a billion people and huge agricultural areas, securing a continuous supply of water for the nation has become paramount. Reservoirs and dams help store water and regulate its distribution, especially in times of drought or water rationing. Over the past few decades, China has therefore embarked on a series of major construction projects. One of the currently most important projects is the Pinglu Canal Project, for which BHS-Sonthofen has supplied eight large BHS twin-shaft batch mixers of type DKX 7.00 and two additional DKX 4.00.
