Abstract
An improved process and apparatus for producing concentrated kaolin slurries and spray dried kaolin particulates through the use of an arrangement where an evaporation system for producing concentrated slurries is coupled with a spray dryer such that off gases from the spray dryer are used to supply heat energy to the spray dryer and to the evaporation system.
