Quick Summary

Prilling is a process used to convert molten solids into spherical pellets, often referred to as prills. This method involves forming the molten material into drops, which then solidify as they fall. The resulting product is a pellet known as a prill. This technique is used to create a specific form for various substances, making them easier to handle and use. The term "prill" was first used in 1944, with the noun form appearing in 1952.12

Ammonium nitrate–fuel oil mixtures
ANFO applications were based on prilled rather than crystallized ammonium nitrate. Prills, or free-flowing pellets, were developed for the fertilizer market, which requires a coarse product that has little tendency to set and can be spread easily and smoothly. A small amount of kieselguhr is generally added to improve the…

…which in granular form (prills) can be blown into the drill hole by compressed air. While AN-FO-type agents are cheaper, their lower power increases the quantity required, and their fumes usually increase ventilating requirements. For wet holes, the prills must be changed to a slurry requiring special processing and…
