Intense mixing of dry and moist minerals TRANSFORMING MATERIALS INTO VALUE

TRANSFORMING MATERIALS INTO VALUE The company BHS-Sonthofen, headquartered in Sonthofen, 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...

TWIN-SHAFT CONTINUOUS MIXER 4 BHS twin-shaft continuous mixer The BHS twin-shaft continuous mixer is a powerful, reliable solution for continuous mixing processes, particularly those with coarse aggregates. This mixer is especially suitable for producing mineral mixtures, RCC, landfill liners, lean concrete, heavy concrete and dry mixtures, etc. BHS also offers complete continuous mixing systems, including weighing systems, dispensing, control technology, service and individual plant components.

Consistent high quality mixtures The counter-rotation of the two mixing shafts as well as the inclined position of the mixing tools result in an intense vertical and horizontal mixing motion. A mixture that is formulacompliant and of a consistently high quality is ensured in conjunction with BHS weighing and dispensing equipment. Material bed protects against wear A natural bed of materials that is formed in the mixing trough during operation serves as protection against wear. For special applications, it is possible to design the mixer with a round trough and with tiles made of a special...

Feed area HI The input material is fed continuously to the mixing tools, which convey it through the mixer. The water is introduced through special nozzles. Discharge area Pi The finished mix leaves the mixer in a constant flow and can be fed to the downstream processing operations. Mixing section ^ The counter-rotation of the two mixing shafts and the inclined position of the mixing tools ensure an intense vertical and horizontal mixing motion as well as continuous transport of the mixture materials.

OPTIONS AND VARIANTS 7 www.bhs-sonthofen.com Comb-type blades  For the mixing of binding, fine-grained materials, special combtype blades are available to remove material caked onto the mixing trough. Turbo coupling  The hydrodynamic turbo coupling prevents both mechanical and electrical load peaks. It is recommended particularly in the case of unstable electricity supply conditions. Central lubrication  A central lubrication system continuously supplies the inner mixing trough seals with grease during mixer operation. D ­ epending on the desired degree of automation, there are different...

Continuous mixing plants Based on the twin-shaft continuous mixer BHS offers complete continuous mixing plants of different sizes. The mixing and weighing platforms are designed so they can be transported in ISO containers to their final destination at low freight cost. The metering system and the control technology enable extremely accurate continuous weighing of the formula ingredients. Continuous mixing plants are suitable for construction sites where large quantities of consistent high quality building materials (such as RCC) are required. Example: Continuous RCC mixing plant in modular...

Weighing platform with dosing station for binding agents  The aggregates are stored in a multichamber dosing system. Controlled feed belt weighers  The aggregates are weighed in a continuous and formulacompliant manner on speed-controlled feeder belts with integrated belt weighers. Collecting conveyor and elevating conveyor  The aggregates are deposited onto the collecting conveyor in layers and transported on the elevating conveyor to the twinshaft continuous mixer. Storage of the binding agents  Binding agents are stored in silos with continuous level measurement, air loosening and a...

Tests give certainty BHS offers customers the opportunity to run mixing tests with their own specific materials at its technical center in Sonthofen. Furthermore, laboratory mixers can be operated directly at the customer’s plant. All test results are recorded, documented and analyzed according to mutually agreed criteria. We would be pleased to advise and assist you. BHS technical center in Sonthofen for customer-specific testing
