Mineral substances & metal salts

High throughput

Top performance

High throughput and minimized resource consumption – this is a central requirement for separation solutions for the production of minerals and zeolites or for the processing of metal salts. Our durable high-performance filters have proven their worth in the chemical industry across the globe.

Benefits at a glance:

  • High throughput rates and operational reliability
  • Durable filter systems
  • Excellent washout results
  • Low total operating costs

Mineral substances

Sophisticated and reliable


Sophisticated and reliable

Vacuum belt filters such as the indexing belt filter (type BF) or rubber belt filter (type BFR) from BHS form an essential part of the process in the production of many minerals and zeolites. The safe processing of mineral suspensions requires different solutions in terms of their process design. Our filter systems are robust, durable and offer a wide range of options for cake treatment. Single or multi-stage cake washing, integrated dry suction and repressing deliver high product purity even with thin cake layers.

Typical applications:

  • Flame retardant: Aluminum hydroxides
  • Aluminum oxides
  • Alumina
  • Sulfates
  • Gypsum, lime and diatomaceous earth
  • Bleaching earth
  • Molecular sieves
  • Fluid catalytic cracking (FCC)
  • Silicon carbide

Metal salts

Safe separation and further processing


Safe separation and further processing

In the processing of metal salts, the chemical industry successfully uses continuously operating vacuum belt filters from BHS. These filters have proven to be particularly suitable for producing high-quality products consistently and reliably by ensuring superior washing of the solid matter. High throughput and low resource consumption means low long-term TOC.

Typical applications:     

  • Nickel sulfate
  • Nickel chloride
  • Copper sulfate
  • Iron phosphate
  • Gold cyanide
  • Cobalt oxalate
  • Iron salts
  • Manganese salts
  • Fluorine salts
  • Tin salts
  • Tungsten
  • Vanadium pentoxide
  • Zinc oxide
  • Rhenium
  • Barium titanium oxide
