We provide process expertise to assist you from the initial feasibility study through to implementation of the most suitable process equipment.

Filters

Rotary pressure filter Highly efficient pressure filtration and cake washing

  • The BHS rotary pressure filter (type RPF) is a continuously operating filter for pressure filtration. It facilitates gas-tight cake handling in a series of separate process steps. Cake treatment can, for instance, comprise single- or multi-stage cake washing and subsequent cake drying. Cake discharge can take place at atmospheric pressure. Application scenarios cover a wide range of industries, including industrial chemicals, fine chemicals, the pharmaceutical industry and the food industry.

Indexing belt filter

  • The indexing belt filter of type BF is a continuously operating, horizontal vacuum filter used for the efficient and gentle separation of sedimenting solids from suspensions. The filter cake formed on the conveyor belt can be further processed in many ways, and this versatility is what makes the indexing belt filter stand out. Moreover, the individual filtrates can be recovered and processed separately.

Rubber belt filter

  • The rubber belt filter of type BFR is a continuously operating, horizontal vacuum filter used for the reliable separation of quickly sedimenting solids from suspensions. It is characterized by high throughput rates and a robust design. Cake treatment involving one or more washing stages is possible.

Candle filter

  • The candle filter of type CF is a filter that operates in a discontinuous manner. The candle-shaped filter elements are arranged vertically in a pressure vessel. The process steps typically performed with this unit are filtration, washing, drying and discharge. All these steps take place under pressure. The candle filter is used for the clarification of liquids with a low solids content. It is a compact unit, operates fully automatically and enables high throughput rates, dry cake discharge and a wide range of cake treatment options.

Dryers

Pressure plate filter

  • The pressure plate filter of type PF is a filter that operates in a discontinuous manner. The plate-shaped filter elements are arranged as a plate stack in a pressure vessel. The process steps typically performed with this unit are filtration, washing, drying and discharge. All these steps take place under pressure.

    The filter is used primarily for cake-forming solid-liquid separation of suspensions with a low solids content that are moderately or very difficult to filter. It is also suitable for adsorptive filtration (as a deep bed or precoat filter). The pressure plate filter is frequently used for clarifying filtration. It is a compact unit, operates fully automatically and delivers high throughput rates.

Horizontal Dryer

  • 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.

Vertical dryer

  • 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.

Mixers

Horizontal mixers

  • 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..

Vertical mixer

  • 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.

Ring Layer Mixer

  • 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.
