          • Horizontal Mixers

              • Horizontal mixer AVA HTC / HTK

              • When it comes to gentle product homogenization or the processing of solid mixtures, solid–liquid mixtures, or pasty mixtures, BHS batch mixers are an excellent choice. The spectrum ranges from powder mixers to heavy-duty designs. Even small quantities can be fed by manually adding them to the mixer. Highly abrasive products also used for construction are processed in machines protected by a special hard-metal plate lining welded to the interior. A common application in the food-feed industry is the preparation of baking mixes. By using special mixing elements and additionally installed shearing heads, the flour and water base substances, as well as other ingredients, are mixed at high viscosity, completely free of lumps and within the shortest time. 

                In continuous operation, BHS horizontal mixers are built for efficient, automated processes in a wide variety of industrial areas. Whether it’s homogenizing, agglomerating, granulating, or humidifying, our mixers support applications ranging from the preparation of polypropylene powders in the chemical industry and flour mixtures for the food industry through to fly ash humidification in the power plant engineering sector or the production of cement mixes for building materials. In other words, BHS continuous mixers deliver operating excellence in every industry.

                Benefits at a glance:

              • Variable processes with frequent product changes

              • BHS batch mixers are optimally suited for variable processes and frequent product changes. These horizontal mixers induce mechanical turbulence or, alternatively, process aggregate mixtures. The task of the mixer is to deliver a homogeneous mixture featuring an extremely small variation coefficient within a batch time (loading/mixing/discharge) of between two and five minutes. Decades of experience and a wide range of equipment delivered in various installation sizes, materials, and styles, speak for themselves. BHS batch mixers are available in various designs, depending on your requirements.

                 

              • Continuous processes with large throughput volumes

              • BHS continuous mixers are excellently suited to large throughput volumes in continuous processes. These horizontal mixers induce mechanical turbulence or alternatively process aggregate mixtures. Our robust technology allows for 24-hour continuous operation, 365 days a year. The raw materials are fed continuously via appropriate dosing units and nozzles, and the finished mixture is continuously discharged via suitably designed discharge elements. Thanks to special agitators, BHS continuous mixers achieve very high throughput rates and optimal backmixing despite compact installation sizes.
            • Vertical mixer

                • Vertical mixer AVA HVW

                • BHS vertical mixers are in operation across all industries. Depending on your application, they process dry or wet, free-flowing, or sticky products. In the food sector, the gentle production of spice blends is a classic application. In the pharmaceutical industry, BHS vertical mixers are used for the production of APIs, while the production of cellulose is the most common application in the chemical industry. The conical mixers are perfectly suited to nearly any mixing task, and the heated version can also be used as a dryer, reactor, or evaporator.

                  Benefits at a glance:

                  • Gentle mixing of delicate materials
                  • Complete discharge in case of frequent product changes
                  • Perfect mixing quality
                  • Easy to clean
                  • Consistently reproducible product quality
                • Gentle and thorough mixing

                • BHS vertical mixers are capable of processing a wide variety of product consistencies and are ideally suited to almost any mixing operation. The rotating helix conveys the product upwards, along the vessel side wall. From here, it drops down into the center and thus once again joins the mixing process. Horizontally arranged connection bridges provide additional cross mixing. This results in greatly reduced mixing times compared to other systems. Depending on the agitator rotation speed and design, gentle folding or intensive mixing can be carried out. The bearing of the self-centering helix is mounted outside of the mixing chamber. BHS vertical mixers are ideally suited to processes where high purity and effective cleaning are required. The vessel shape also supports quick and optimal discharge.
              • Ring Layer Mixer

                  • Ring Layer Mixer AVA HRM

                  • Large throughput rates despite a small installation size – this is precisely what the BHS ring layer mixer is built to deliver. One application example is micro granulating in the chemical industry, for example, in the field of detergent production. Here, poorly flowing powders are transformed into a highly fluid product through micro granulation. In the area of pulp processing, our annular layer mixers come into their own, for instance, when it comes to preparing suspensions (solids plus solution) that serve as base material for subsequent staple fibers production. Compared to conventional systems, the ring layer mixer achieves very rapid decomposition of the individual fibers in the solution. In the pulp and pastes production processes of the food industry, the decisive argument for the ring layer mixer is that it offers optimum hydro neutralization of the product, for example, using steam.

                    Benefits at a glance:

                    • High circumferential speeds up to 50 m/s
                    • Agglomerate-free mixing in the high-turbulence ring layer
                    • Perfect mixing quality
                    • Easy to clean
                    • Consistently reproducible product quality
                  • High peripheral speeds

                  • The ring layer mixer agitator system delivers high peripheral speeds of up to 50 m/sec. The resulting centrifugal force brings the product outwards into a ring layer on the vessel side wall. The high speed difference between the rotating agitator and the mixing drum, combined with the use of different mixing elements, guarantees a high and agglomerate-free mixing intensity. Fluids are injected tangentially into the product through special nozzles. At such high speeds, the slightest imbalance could jeopardize the continued safe operation of these plants, which is why we bring our full experience, expertise, and sophisticated technology to bear to guarantee the flawless design of every single ring layer mixer we ship to our customers.
                • Dryers

                    • Horizontal Dryers

                        • Horizontal Dryers

                        • Many production processes generate water and/or solvent-moist intermediate products that must be dried before further processing, distribution, or disposal is possible. Drying is often carried out in two steps: an upstream, less energy-intensive mechanical method for expelling the main moisture (e.g. filter) and the subsequent thermal final drying. BHS horizontal dryers AVA HTC-T and HTK-T are used in the cellulose industry, as dryers for flame retardants in the chemical industry, and for evaporating high-boiling substances (for example, hydrocarbons) from contaminated environmental industry substances under vacuum conditions.

                          Benefits at a glance:

                          • Short drying times
                          • Adjustable process parameters
                          • Uniform temperature & product moisture
                          • Efficient drying of even highly viscous products
                          • Vacuum & high pressure operation
                        • Short drying times in batch and continuous mode

                        • The product fed into the machine comes into direct contact with the heated drying elements (drum, head ends and/or shaft, and shovels) and is continuously shifted by the rotating agitator. Half-pipe coils or double jackets are available for heating the drum. Thermal oil or steam are most commonly used as heating fluid, or an electric heater can be used for high-temperature applications.

                          The constant circulation along the heated surfaces leads to uniform moisture expulsion and creates a uniform temperature and product humidity in the drying mixer product chamber. Vapors are removed via vapor filter systems specially constructed by BHS. The shape and angle of the shovels ensure optimal heat exchange between product and side wall. Separately driven choppers dissolve lumps, thus resulting in a fine-grained to powdered material consistency. Benefits include very short drying times, which can be further reduced by including a vacuum dryer in the design.s

                      • Vertical Dryers

                          • Vertical dryer AVA HVW-T

                          • BHS vertical dryer application scenarios range from laboratory to large-scale production, and from highly sensitive pharmaceutical applications to rugged environmental engineering. Customers frequently chose this versatile machine type as the basis for tailored solutions. This is a tiny sample of the possible applications: drying of APIs for the pharmaceutical industry, sterilizing of spices in the food industry, drying of ion exchange resins in the chemical industry, as well as coating of iron powder with additives in metallurgic applications. A multitude of process steps can be implemented using BHS vertical dryers.

                            Benefits at a glance:

                            • Short process times with maximum product protection
                            • Adjustable process parameters
                            • Uniform temperature and product moisture
                            • Seal positioned outside the product chamber
                            • Operation under vacuum and high pressure
                          • Short process times and gentle product handling

                          • BHS vertical dryers consist of a cone-shaped vessel with mixing helix installed close to the side walls. They were developed for shorter process times with maximum product protection. The mixing helix is a double-threaded (or single) conical spiral that is connected to the shaft via steps. It conveys the product upwards along the heated side wall, after which it sinks downwards again inside the process chamber. This results in a uniform temperature and product humidity across the entire product chamber. To further reduce the drying time, the helix can additionally be heated and a vacuum can be applied. In the convective heating variant, steam or hot air is applied to the mixer interior, and the drying elements can also be heated.s
