Situation 
• Permeability of the sinter mix on the strand unknown
• Water dosing in the granulation suboptimal 
• Inhomogeneous burn-trough
• Losses of productivity and quality
 
Solution 
• Injection of air trough permeability probes
• Measurement of permeability on the strand by the pressure loss
• Analysis and optimisation of granulation and water dosing
• Control of burn-through and strand speed

Benefits
• Sinter process more steady
• Raised sinter quality
• Increase of permeability and production
• Reliable permanent operation
• Release of staff
