FERTILIZER GRANULATION METHOD

摘要

Fertilizer granulation method for incorporating urea directly into the matrix of fertilizer pellets. The process involves introducing the urea in a liquid form i nto the matrix and then progressively cooling the mixture of pellet and urea to recrysta llize the urea within the matrix of the pellet. The result is a substantially harder parti cle relative to pretreatment hardness, reduced solubility for longer lasting pellets and subs tantially reduced dust and other handling problems of the formed pellets.
