Roaster Feed System

Improved safety, easier operation and online equipment monitoring and control capabilities by utilizing the Metso Outotec® Roaster Feed System. Our slinger belt feeder can handle high feed rates through a single machine on a continuous basis all year round.
  • Reduces operating costs
  • Eliminates false air ingress to the roaster through automatic flap valves   
  • Sensors signal via DCS offers operators continuous monitoring control   
  • Reduces material spillage via roaster feed gate sealed system   
  • Longer lifetime of slinger belt secures higher thermal resistance and longer durability
  • Easy movement through handle bars and rollers with lock system   

The spillage flap valves at the bottom opening improves the process conditions inside the roaster, particularly in the feed zone area. As a result, sulfate formation above the roaster feed gates will be reduced significantly, minimizing calcine accumulation and build-ups at the roaster wall. Such accumulation is a critical safety issue and a risk to damage the roaster’s cooling elements in the event that calcine accretion lumps falling down from the roaster wall.
