Abstract
A process for the continuous drying of chemical products by milling fluidization, in which a fluidized bed of particles of an inert carrier, e.g., quartz sand having a particle diameter of 0.5-1.0 mm., is maintained and the chemical product to be dried is introduced in a wet state, e.g., wet solid or paste or suspension, into the fluidized carrier bed. The chemical product dries on the surface of the inert carrier particles and dry particles of the chemical product leave the relatively large and heavy carrier particles and are carried off in the exit gas. The carrier particles, however, are too large and heavy to leave in the exit gas and so remain in the fluidized bed. If desired, the dried product particles can be further dried, for example by additional drying gas in a cyclone chamber, after which the dried particles are separated from the gas which can be vented and/or recycled.
