MULTIPOL multiple hearth furnace

With the MULTIPOL, thyssenkrupp Industrial Solutions has taken the lead in the market for the supply of multiple hearth furnaces, particularly in the refractory materials industry. The MULTIPOL is ideal for thermal processing of raw material with very small particle sizes as well as filter cake and enables precise control of the temperature profile. The multiple hearth furnace is the best choice for practically all calcination processes where highest product quality is demanded.

Main characteristics

  • Moisture content levels of over 50% in the feed material (e.g. filter cake) are acceptable
  • High flexibility and precise control of the temperature profile (± 5 °C) to achieve highest product qualities
  • Suitable for processing very small particle sizes
  • Insensitive to fluctuations in chemical and physical properties and moisture content of the feed
  • Application temperatures up to 1,100 °C
  • Suitable for oxidation and reduction processes
  • Suitable for liquid and gaseous fuels (including low calorific value gas)
  • Highest availability
  • Low maintenance costs
  • No product loss, in contrast to conventional calcining systems

Fields of application

  • Calcination of industrial minerals, e.g. magnesite (CCM), dolomite, limestone and clay
  • Calcination of flotation concentrates and filter cakes
  • Thermal treatment of ores, minerals, earths, sands and biomass
