Abstract

A process for activating clays having high residual moisture by: feeding wet clay into a device for drying, comminuting the previously dried clay in a device for comminuting, thermally activating the comminuted clay in an entrained flow reactor or in a fluidized bed reactor in which the comminuted clay is in suspension in a hot gas, removing the gas from the entrained flow reactor or the fluidized bed reactor in a device for removing, and cooling the thermally activated clay in a device for cooling with a cooling gas, and to a corresponding plant. The cooling gas, heated after cooling the thermally activated clay, is combined with the gas from the reactor, and the combined gases are introduced into the drying device. The drying air is filtered after drying, and clay removed by filtration is unified with the dried clay.
