Close-up of our ceramic steering plates at the machine after 12 years

Ceramic steering plates 12 years after assembly and under the following working-conditions:
5 days per week, 6-7 hours a day
Media:
ceramic tiles in green stage or after furnacing.

After approx. 12 years the ceramic plates can be turned and reused. Time for changing : approx.. 2-4 hours. The ceramic plates are fixed with assembly adhesives or heat-resistant special adhesives.
