Safety nets protect workers in preheaters
Safety nets make it possible to safely arrest falling debris and assure the safety of the employees working below. An important aspect is the fact that the brakes must be mounted on the exterior of the riser duct. The safety net is also installed in the riser duct from outside. Dyckerhoff is now equipping all its clinker plants with such nets, in view of the extremely good experience gained up to now and the high safety level achieved for employees working in the kiln inlet chamber and riser duct.

The following safety precautions are customary in the cement industry before work is performed in preheaters:
Visual inspection of the masonry by experienced colleagues for condition and encrustations
Removal of encrustations in the riser duct from the inside by industrial climbers or from...
