  • Patent number: 4962279
    Abstract: An improvement is disclosed applicable to the production of calcined and hydrous kaolins in particulate form. A process and system are disclosed in which the calciner is integrated with a filtration process and a preceding spray dryer by passing the dust-laden calciner hot off-gases to the spray dryer to achieve savings in energy. Waste heat from the calciner, and concomitantly dustlike clay particles carried in the off-gas, are thereby passed to the dryer and subsequently treated and their values recovered.
