Gypsum Industry

Gypsum Industry

The most important step in the production of gypsum building materials and plasterboards is gypsum calcination. This industry also is characterized by a wide range of different processes:

  • gypsum kettle
  • moving grate
  • rotary kiln
  • calcining mill

Various fuels and a high humidity content can lead to difficult chemical conditions. In addition, a distinction must be made between the use of natural gypsum and FGD gypsum as raw materials.

Here too, KAYSER can offer the optimal filter media out of all available materials.
