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

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

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.

Innovative mixing concept features clever details

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

Four large BHS mixers for a land-reclamation project in Hong Kong

April 2024

Hong Kong is in the midst of a housing crisis. The megacity is bursting at the seams, with the government always on the lookout for new properties. Many residents also depend on living near the city center, in close proximity to its towering financial headquarters. To address this problem, Hong Kong has been working to reclaim land from adjacent bay areas for many years. The TKO project in the east of the city is part of this effort. For this prestigious project, BHS-Sonthofen has supplied four large twin-shaft batch mixers of type DKX 5.00 for the production of concrete.
