Evaluation Of Rotating Fluidized Bed As A Dry Coater, William Christopher Dunphy
Theses
Coating of particles is normally carried out with the use of environmentally unfriendly solvents. Development of dry coating methods is therefore quite important.
A Rotating Fluidized Bed was constructed, instrumented and verified as to operation. Twelve coating experiments were carried out with PMMA 200μm mean diameter as host and alumina 0.25μm primary particle size as guest with the RFB being operated in the fully fluidized range.
In all analyzed samples, coating was observed. Analysis was carried out on the qualitative basis by SEM and EDX.
