Digesters

Chemical leach and extracting processes in the minerals industry are performed in rotating spherical pressure vessels called Rotary Globe Digesters. In addition to ores, fine and long fiber paper and proteins and fibrous materials products are processed in these rotating pressure vessels.
   Reaction rates are enhanced by increased pressure and the unique blending and folding agitation that occurs in a rotating sphere. Low-grade ores are improved by the acid or caustic leaching of impurities from the ground material. In some cases, desired materials are dissolved and removed in the liquid phase. Materials subject to size degradation or caking can be successfully blended and dried in a rotary globe vessel.
   McGill AirPressure supplies Rotary Globe Disgesters in sizes up to 20 feet (6,100 mm) in diameter. Our Globe and Cylindrical Digesters offer the versatility of temperature, pressure, and mixing control and the reliability required to withstand hostile environments of simultaneously applied high temperature, high pressure, and acid/alkaline solutions.

Rotary Globe Digesters installed at a major chemical manufacturing facility.
