    摘要： A fluidized bed apparatus comprises a chamber having a perforated floor, a spray nozzle located in the chamber above the perforated floor, whereby material to be granulated is introduced into the chamber in the form of a solution or dispersion, means for passing heated gas upward through said perforated floor, whereby solid particles of said material are formed in said chamber, particle size-reducing means outside of said chamber, whereby particles larger than a first predetermined size are reduced in size, a screw shaft located above said perforated floor and communicating with said size-reducing means, whereby particles are withdrawn from said chamber and conveyed to said size-reducing means, a pipe having one end located downstream of said size-reducing means and its other end communicating with said chamber, and means for generating a flow of air whereby particles smaller than a second predetermined size exiting from said size-reducing means are returned through said pipe to said chamber.

    摘要： A METHOD FOR CONTROLLING DUST IN A NORMALLY-HIGHDUSTING MATERIAL WHICH INCLUDES WORKING THE MATERIAL WITH A MINUTE AMOUNT, LESS THAN 1% BY WEIGHT OF THE MATERIAL, OR A FINELY DIVIDED FIBRILLATABLE POLYTETRAFLUOROETHYLENE (HEREINAFTER REFERRED TO AS PTFE) TO FORM A DRY MIXTURE WITH THE MATERIAL WITHOUT CHANGING THE PRIMARY PRACTICLE SIZE OF THE MATERIAL, AND CONTINUING TO WORK THE MIXTURE SUFFICIENTLY SO AS TO ESSENTIALLY GEGATE THE DUSTING OF THE MATERIAL WITHOUT APPRECIABLY CHANGING IT PHYSICAL PROPERTIES. FINE POWDER PTFE OBTAINED BY COAGULATION OF A COLLODIAL AQUEOUS DISPERSION OF THE RESIN IS USED IN THE "DRY" TREATMENT OF NORMALLY-HIGH-DUSTING SUBMICRON AND SUPERFINE MATERIAL. AGAIN, THE NORMALLY-HIGH-DUSTING MATERIAL MAY BE MIXED WITH COLLOIDAL AQUEOUS DISPERSION OF THE RESIN, IN AN AMOUNT INSUFFICIENT TO CHANGE THE ESSENTIALLY DRY CHARACTER TO THE MATERIAL AND WORKED, AS DESCRIBED HEREIN, TO NEGATE DUSTING OF THE MATERIAL. ALTERNATIVELY, THE FINE POWDER OF THE COLLOIDAL DISPERSION MAY BE USED TO SLURRY THE MATERIAL IN A "WET" TREATMENT TO FACILITATE THE HOMOGENEOUS DISPERSION OF THE RESIN; THE SOLID CONTENT OF THE SLURRY MAY THEREAFTER BE WORKED IN THE WET STATE, PREFERABLY AS A PASTE, OR WORKED IN AN ESSENTIALLY DRY STATE, WITH A MASTICATING OR KNEADING ACTION, AS BEFORE. IN ANOTHER EMBODIMENT, FOR CONTROLLING DUSTING IN A NORMALLY-HIGH-DUSTING MATERIAL, A METHOD IS DISCLOSED WHICH INCLUDES MIXING THE MATERIAL WITH FINELY DIVIDED FIBRILLATABLE PTFE IN AN AMOUNT IN THE RANGE FROM ABOUT .02 TO ABOUT 3% BY WEIGHT IN THE PRESENCE OF A LIQUID PROCESSING AID, IN WHICH THE MATERIAL MAY OR MAY NOT BE SOLUBLE, AND SPRAY DRYING THE SOLUTION OR SLURRY SO THAT UPON SEPARATION OF THE LIQUID PROCESSING AID, A DRY TREATED SOLID MATERIAL IS RECOVERED, VIRTUALLY INDISTINQUISHABLE FROM UNTREATED MATERIAL, BUT CHARACTERIZED BY A SUBSTANTIALLY COMPLETE ELIMINATION OF ITS NORMALLY-HIGH-DUSTING NATURE. NOVEL DUSTLESS COMPOSITIONS ARE FORMED BY WORKING A NORMALLY-HIGH-DUSTING, SUBMICRON OR SUPERFINE MATERIAL WITH A FIBRILLATABLE PTFE RESIN IN AN AMOUNT FROM ABOUT 0.02 TO ABOUT 1% BY WEIGHT, BASED ON TOTAL SOLIDS, UNTIL A VISUAL INDICATION OF NON-DUSTING IS OBTAINED. EVEN COARSE, DUSTY MATERIALS UP TO ABOUT 100 TYLER MESH, WHICH CONTAIN FINES AND SUPERFINES ARE RENDERED DUSTLESS. DUSTY MATERIALS WHICH INCLUDE FINES IN THE RANGE FROM ABOUT 10U TO ABOUT 44U OR SUPERFINES UP TO ABOUT 10U IN SIZE ARE PARTICULARLY SUITABLE FOR DEDUSTING TREATMENT.

    摘要： Described is a process for the production of substantially dustless water-soluble dye or optical brightener compositions, which process comprises mixing a dry, solid inorganic salt, heated to at least 50.degree. C., with a mixture of at least one dye or optical brightener, an adhesive as e.g. sorbitol, a dust binding surface active agent and further additives. Such compositions are negligibly dusty to dustfree, and retain these properties even after storage for months, particularly in the case where spray-dried material is used.
