Rotary Furnace - an overview ScienceDirect Topics

Rotary furnaces range in size from 3 to 10 m³ and produce between 3 and 30 tonnes per charge based on the metal content. The slag from a rotary furnace in general contains low levels of lead (2–4%). Some plants may tap bullion and slag together and remove the slag after solidification. A continuous rotary furnace is operated by Nova Pb [8 ...

The Tilting Rotary Process :: Total Materia Article

Tilt rotary process route: 1. Furnace is charged very quickly using the much larger charge opening. 2. Melting by double pass burner arrangement. Saving energy with faster melting. 3. The furnace is tilted to pour out the aluminum. The dry slag remains in the furnace – with no time wasted in opening tap hole.
