摘要： 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.

摘要： A method of obtaining crystals of a solute in which the fresh solution is initially cooled by contacting with a mother liquor containing crystals below the desired grain size to produce a mother phase in a state of incipient crystallization. The latter is crystallized with or without further cooling by passing it through an elongated crystallizer body with angularly adjoining portions swung around an offset axis and having cooled walls. The resulting slurry is then continuously filtered to separate out the crystals of the required size and form the mother liquor containing particles below the required size.

摘要： An apparatus for crystallization which utilizes a treating device for the formation of a crystal slurry having a prismatic drum at the inlet end of the device and a zigzag body eccentrically connected to the wide end of the drum and formed by ducts which have their axes intersecting the axis of the drum, the final duct section terminating at a ring which is coaxial with the drum. The duct walls are planar as well. The entire system is closed and includes a filter having a prismatic drum and duct arrangement but with walls which are perforated.
