Case Study: Wurster Coating of Metal Powder

This trial contributes to the development of a novel coating process for fine particles with diameters of around 40μm. The innovation lies in the use of Freund-Vector’s patented Wurster spray system that utilizes an outer sleeve placed around the Wurster gun called the Wurster Accelerator. The accelerator creates an air curtain that diverts product away from the spray nozzle tip, optimizing product movement through the spray zone and reduces processing times. The system is suited for the coating of particles ranging from fine powders (~10 micron) up to small pellets (2-3 mm).
