Abstract
An improved Wurster-type coater including a separator screen located within the Wurster tube in surrounding relationship to the spray nozzle and forming an annular volume through which at least a portion of smaller feed material particles are permitted to preferentially enter the spray pattern before the larger-sized particles can do so, thereby causing the smaller particles to become agglomerated first, resulting in finished product having a more even distribution of particle sizes.
