The briquetting units shape fine materials into larger forms of varied shapes, sizes and volumes (from a few cc up to 600 cc and more) : these characteristics are defined according to the product end use.

If the cohesive forces (particulate cohesion, valence forces, recrystallization, van Der Waals forces…) between the particles are low, a binder has to be used before agglomeration. The physical properties of the feed material, the end use of the briquettes and the cost of binder addition have to be taken into account before a selection is made. A large variety of (liquid or solid) binders is offered: starch, bentonite, bitumen, lime, cement, water, flour, lignosulphonates, molasses, polymer, resin, sodium silicate, etc…

The briquettes are obtained at a low or high pressure and can undergo mechanical or thermal treatment according to the characteristics of the processed material, the binder used and the desired end product. Considering the large variety of products to be processed and the binders used, the range of mixers designed and proposed by SAHUT-CONREUR is specifically adapted to each type of briquetting:

  • Vertical mixers or pug mills, for instance for briquetting of coal with bitumen.
  • Twin screw mixers, for instance for briquetting of some chemicals with water ; these mixers can be equipped with heating or cooling jacket, as the case may be.
  • Horizontal or ploughshare mixers, for instance for briquetting of some minerals with molasses ; these mixers can also be equipped with heating or cooling jacket, as the case may be.

Fields of application

You will find in this page, examples of industrial applications using our briquetting technology. Of course this list is not exhaustive and we hope that you will not hesitate to contact us in order to obtain more technical information about ways to process your product:

  • Chemicals (sodium sulphate, sodium chloride, carbonates, sodium cyanide, potassium cyanide, iron sulphate, potassium bromide, boric acid, urea, ...).
  • Minerals (alumina, bauxite, lime, dolomite, gypsum, china clay, magnesia, fluorspar, paint pigments, sulphur, ...).
  • Gypsum from power station flue gas desulphurisation
  • Minerals (chromium, cobalt, copper, iron, manganese, lead, zinc, ...)
  • Metallic oxides (Waelz oxides), rare earth oxides, zirconium hydroxide, ferro-alloys, molybdenum trioxide, zircon sand...
  • Steel turnings
  • Coal : production of briquettes for home or industrial heating (partial coke oven charge, briquettes treated to obtain formcoke, briquettes for gasification).
  • Coal for production of activated carbon
  • Lignite, peat, etc..
  • Charcoal
  • By-products from steel mills and metallurgy.
  • Graphite, carbon black
  • Phosphate (hot or cold briquetting)
  • Clay
  • Detergents
  • Frozen food
  • Sugar
  • Glass batch
  • Steelworks waste materials and by-products (sludge, mill dust, sintering fines, mill scale, coke fines...)
  • Dried sewage sludge
