Solutions for the safe separation of substances

Continuous or batch operation

Separation solutions from BHS-Sonthofen are the first choice in the chemical industry. Whether in continuous production or in batch operation, our systems deliver high quality and impressive performance. The BHS experts put their decades of experience to work for you, advising you on process planning for a vast range of process steps in the production of chemical products. Together with you, we develop customized solutions for the processes of filtration, drying, mixing and reacting that best meets your application needs.

Highly efficient processing of the solid

In addition to the rotary pressure filter, the indexing belt filter (BF) is also used in the processing of a wide range of chemical products – especially for applications involving abrasive solids. Both filter systems are highly efficient due to multi-stage cake processing.

Together with your input, we design the separation solution that best suits your needs. The solution we will develop guarantees maximum yield, high product quality and minimizes the total cost of ownership.

Benefits at a glance:

  • Self-regulating filter systems
  • High system availability
  • Safe operation
  • Multi-stage cake treatment
  • High yield and product quality
  • Low total operating costs

Agrochemicals

Safe production of agrochemicals

Safe production of agrochemicals

For manufacturers of plant protection products such as pesticides, fungicides and herbicides or fertilizers the most suitable closed system for the production of agrochemicals is the rotary pressure filter (RPF). The continuously and fully automatic high-performance filter offers maximum safety and requires no manual intervention other than maintenance. The machine facilitates gas-tight cake treatment in several discrete process steps.

When it comes to homogenizing and drying agribusiness powders and granulate formed products, BHS vertical dryers and mixers are the tools of choice. The fragile products are processed rapidly and particularly gently, and the reproducibility of recipes is ensured. The special shape of the mixing container means that the product is almost fully discharged at the bottom side while the agitator is running. For cleaning purposes, the machines are highly accessible or alternatively, cleaning processes can be automated. Design and construction are carried out in accordance with GMP, and there is a wide choice of application-specific variants.

Safe processing of bio-based chemicals

In the processing of chemicals based on renewable raw materials, the filter systems from BHS-Sonthofen ensure high product quality and yield as well as efficiency in the treatment of the solids. Examples include cellulose derivatives or bio-based polyamides.

Products:

  • Brominated and chlorinated compositions
  • Melamine and phosphate mixtures
  • Ammonium, antimony, and boron compounds
  • Other inorganic flame retardants

Conditioning of Flame Retardants

BHS dryers, mixers and reactors are ideally suited for conditioning flame retardants. Horizontal or vertical, from 1 liter to 50,000 liters, with reaction temperatures of up to 800°C (1472°F) and <25 mbar (0.36 psi) absolute pressure. The mixing, drying, and reaction processes can take place in one machine. In the reactor variant, a typical application is cross-linking of melamine and phosphoric acid to create melamine (poly)phosphate. In the drying mixer variant, red phosphorus, ammonium (poly)phosphate, and melamine (poly)phosphate are dried, while the mixer variant is suited, for example, to coating flame retardants with silanes to improve the surface structure.

Our machines in use
