Particles at the size between 100 and 3,000 µm have many benefits in industrial processes and consumer products. They are not dusty, they flow freely and they can be utilized by automated transport and dosing devices. Since they do not spill (like liquids) or emit dust (like powders) they are also very safe products. Fluid bed technology can be used to generate such particles from liquid and or powdery raw materials. The liquid may be a solution, a suspension or a melt and the end product can be customized for attributes such as particle size distribution, spherocity and bulk density.
Multiple industries also see a strong interest in adding a layer to the granule’s surface, thus adding a special function to the granule or controlled release of a core material. Fluid beds can also be used for such applications and can add coatings of various types at coatings weights between .5% to 20%. In addition to the production methods above, applications for the detergent, cosmetics and food industry will be presented.
