Prill
From Wikipedia, the free encyclopedia
Prill is a small aggregate of a material, most often a dry pellet, usually formed from a liquid. Prills are formed by allowing drops of the prill substance to congeal in mid-air by being dripped from the top of a tall Prilling Tower. Fertilizers (ammonium nitrate, urea, NPK) and some detergent powders are commonly manufactured as prills.
