Installation for continuous treatment of molten materials to obtain pelletized products

Apparatus for treating molten mineral materials, including metallurgical slags, for recovery of expanded particles, granules or pelletized products, comprising

• means for forming the molten material into a sheet and subjecting the molten sheet to spraying with water jets;
• a rotary drum having blades and means to rotate said rotary drum in the path of the stream of partially expanded and water jet cooled molten material to fragment said stream and project the formed particles into the atmosphere where cooling continues;
• means for receiving the partially cooled particles projected by said rotary drum;
• said rotary drum being fluid-tight and including internal cooling means for effecting cooling of said fluid-tight drum by internal circulation of water in a closed circuit;
• said rotary, fluid-tight drum having blades of a scoop or chistera shape;
• and
• said means for receiving the cooled particles comprising a series of vibratory tables arranged in a cascade, the last and farthest from said rotary drum of which receives the contents from the tables upstream thereof, and which last table delivers collected dry pellets onto a conveyor means.
