Fired phosphor powder is deagglomerated by introducing a slurry thereof to the bottom of a vibratory mill while water is added to the top of the mill. This establishes a vertical gradient in the phosphor concentration in the slurry, the bottom being thicker than the top. The fine phosphor particles move out faster through an outlet at the top, while the coarse particles receive longer milling time.
