The process of recycling refractory materials involves sorting to remove contamination before being primary crushed and dried. After this, we process the material to individual customer specifications. We make sure that we carry out chemical analysis at each stage of the process to ensure consistency.

To make this more visible we have two videos available that explain our work with these materials in short:

  1. Sustainable Refractory Recycling
  2. Refractory Toll Processing
