Method for agglomerating suspended particles
Abstract
Abstract A PLURALITY OF FINELY SUBDIVIDED SOLID PARTICLES IS CONVERTED INTO A MASS OF DISTINCT AGGLOMERATED BODIES BY SUSPENDING THE SOLID SUBDIVIDED PARTICLES IN WATER HEATED TO AT LEAST 80*C. THE PARTICLES MUST BE SUCH THAT WATER IS INERT THERETO AND WHICH ARE AT MOST SLIGHTLY SOLUBLE IN WATER. THE GRANULATING AGENT IS A SYNTHETIC ORGANIC PLASTIC WHICH IS DISSOLVED IN A LIQUID ORGANIC SOLVENT AT AT LEAST 80*C. THE GRANULATING SOLUTION IS THEN ADDED TO THE SUSPENSION AND THE THUS-FORMED MIXTURE IS MAINTAINED, PREFERABLY UNDER STIRRING, AT AN ELEVATED TEMPERATURE BELOW 100*C. AND SUFFICIENTLY HIGH TO FORM GRANULES OF THE FINELY SUBDIVIDED PARTICLES AND THE GRANULATING AGENT SO THAT A PLURALITY OF AGGLOMERATED BODIES EACH COMPRISING A PLURALITY OF THE FINELY SUBDIVIDED PARTICLES ADHERED TO EACH OTHER BY THE GRANULATING AGENT WILL BE OBTAINED.
