Where engineering art meets customer wishes!

Versatility, robust design, high operational safety and variable throughput rates—these are the attributes characterising our rotary kilns. Currently furnished with eleven different plants, directly or indirectly fired and if needed coupled with peripherals, we can fulfil customer-specific demands for different material systems, material properties and process conditions.

Treatable inputs:

  • Fine grain materials
  • Coarse grain materials
  • Suspensions
  • Powders
  • Granulates
  • Moulded forms





The rotary kiln technology is a thermal process for calcination, sintering, pyrolysing and burning of powders and granulates.

Test facilities

With eleven different test facilities of our direct and indirect heated rotary kilns we can individually serve the customer-specific requirements for various material systems, material characteristics and process conditions in customer trials and small amount productions.


The IBU-tec rotary kilns are used for calcination, sintering, pyrolising and firing. Treatment temperatures range from 50 °C – 1,550 °C.


Due to our unique technical equipment with a wide range of roatary kilns and plant peripheries, we are well prepared for various applications.
