DMXDry Powder Batch Mixer

The benchmark in mixing technology

Headquarters of BHS-Sonthofen in Germany

The company

BHS-Sonthofen, headquartered in Sonthofen, Germany, is an owner-operated group of companies in the field of machine and plant engineering. We offer technical solutions in the field of mechanical process engineering, with a focus on mixing, crushing, recycling and filtration. With over 300 employees and a number of subsidiaries, BHS-Sonthofen has a global presence.

Over 125 years of experience in mixing technology

BHS-Sonthofen invented the first twin-shaft batch mixer back in 1888 and has been systematically upgrading the design ever since. Today, BHS has a broad product range of batch and continuous mixing systems for numerous applications. Based on this know-how, the DMX series of twin-shaft batch mixers has been specially developed to meet the particular requirements of mixing dry materials.

Worldwide service

BHS offers quick and reliable service worldwide with its technical customer support and spare parts stock on three continents for all machine types.

DRY POWDER BATCH MIXER

BHS dry powder batch mixer DMX

Twin-shaft mixing technology is suitable for all formulas and offers a wide range of benefits. The mixing technique has a significant effect on the quality of the mixture and the economic efficiency of the production process.

Superior machine technology

Compact design

Compared with other mixing systems, twin-shaft mixers are filled to a significant higher filling level, making them more compact for a comparable throughput rate. In the case of new plants, mixers of the DMX series are ideal because of their small dimensions; for modification to existing plants, they allow the installation of a more powerful mixer in the available space.

Maintenance-friendly and robust design

Our machines are characterized by a sturdy and durable design, providing safe and easy access for maintenance work.

Residue-free discharge

Residue-free discharge of the mixer is carried out using two large, water-tight and twist resistant discharge door flaps.

Low wear

The compact design and the high filling level minimize the ratio of wearing surfaces to batch volume.

Generating valuable products

Consistent and reliable mixing results

Thanks to the proven design and arrangement of the mixing tools, you will achieve consistent homogeneous mixtures batch after batch in less time.

Advantages of the twin-shaft principle

Compared with single-shaft mixers, twin-shaft mixing technology offers considerably better mixing with short mixing cycles. Thanks to the sophisticated mixing mechanism with the directed three-dimensional motion pattern, the speed of the mixer can be less compared to single-shaft or intensive mixers while still producing a greater mixing effect.

Gentle processing of the mixture

The special spiral-blade mixing mechanism and the gentle material transport, combined with the generation of high relative movements of each single particle, ensure that sensitive components in the material to be mixed, such as perlite, styrofoam or expanded concrete, are protected. The grain structure of all batch ingredients is thus preserved.

FUNCTION AND MIXING CONCEPT

Functional principle: spiral mixing tools

ADVANTAGE OF THE THREE-DIMENSIONAL MIXING CONCEPTUnlike single-shaft systems which move the mixture to the center of the machine, the three-dimensional mixing concept of the twin-shaft batch mixer results in a more intensive exchange of materials and thus in shorter mixing cycles with reduced energy consumption.

Mixing tools arranged in the form of an interrupted spiral on each mixing shaft

Two counter-rotating mixing shafts with the mixing tools overlapping in the longitudinal center area of the mixer

Counterblades positioned at the ends of the shafts Moderate circumferential speed of the mixing blades

Mixing concept

Generation of a circular three-dimensional pattern for rapid mixture of batch ingredients

Intensive material exchange in the turbulent overlap area of the two mixing circles

Optimal conversion of the energy input into intensive relative movements of the mixture

Rapid movement of all materials throughout the mixer during the entire mixing process

Functional principle: movement of the mixture

OPTIONS AND ACCESSORIES

Mixing trough cover 1

The dustproof mixing trough cover is equipped with large maintenance hatches opened with the aid of gas springs. Optional custom connections for feeding, venting or color and fiber addition are available upon request. Dust can be successfully captured by means of vent socks or an active filter.

Electrical terminal box 2

All the cabling can optionally be connected to a terminal box for easier installation.

Mixing tools 3

The mixing tools used, based on our spiral-blade mixing mechanism, are adapted according to the abrasiveness of the batch inigredients and the need for residue-free discharge (3b smooth mixing tools).

Agitators 4

The mixer can be fitted with agitators, installed along the longitudinal side of the trough, for the purpose of disintegrating undesired agglomerations. They work highly efficiently, due to the high filling level of the mixer, as they are in permanent contact with the circulating mixture.

Wear protection

Depending on the abrasiveness of the mixture, various liner variants are available for the mixer.

Dustproof discharge hopper

Discharge hoppers, individually adapted to plant requirements, can be designed and supplied for receiving the mixture and for transfer to the downstream conveyor systems.

Air compensation pipe

Air compensation pipes are used to compensate for the pressure fluctuations between discharge hopper and mixer.

Periphery

Drawing on a wealth of experience in the planning and construction of special plants, retrofits and plant extensions, BHS is able to supply the entire periphery, from the weighing system to the complete mixing station.

Sampling

Depending on the specific requirements, different sampling devices are available with either pneumatic or hydraulic actuation. These are installed on the longitudinal side of the trough. The sample can alternatively be filled into an automated sampling carousel or a conventional container.

CUSTOMER TRIALS

Tests give certainty

BHS offers customers the opportunity to run mixing tests with their own specific materials at the BHS technical center in Sonthofen. Furthermore, laboratory mixers can also be operated directly at the customers location to develop solutions to challenging problems. We would be pleased to advise and assist you.
