摘要

A lime hydrating plant is provided with an external cooler 16 in which the rawer solids portion which is recirculated into a return flow fluidizer 2 (hydrater) is cooled outside the hydrater. This means that less water has to be atomized into the return flow fluidizer 2 than by known plants in order to keep the adequate temperature essential for the hydrating process. Thus dew point decrease may be avoided and a highly reactive hydrated lime may be produced.
