Abstract
Method and apparatus for the thermal treatment of slurries such as slurries of magnesite hydrate or the like. The method involves suspending the slurry in an airstream, passing the airstream with the suspended slurry particles into contact with a heated gas stream in a dryer, passing the thus-dried slurry to a multi-tiered heated kiln, introducing heated gases into the kiln for drying contact with the thus dried slurry, and passing the exhaust gases from the kiln to the dryer to serve as the heated gas stream.
