ABSTRACT:
Sintered phosphor chunks are deagglomerated by feeding the chunks into a crushing machine to break them into pieces small enough to be vacuum-transported to a vacuum tank from which they drop into a controlled device which distributes the phosphor pieces into a uniform flow. The pieces are then uniformly fed into a roll crusher having an upper pair and a lower pair of rolls, which crush the phosphor into pieces small enough for use in preparing phosphor coating suspensions.
