GRANULATION METHOD OF UREA CONTAINING FERTILIZER |
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 into the matrix and then progressively cooling the mixture of pellet and urea to recrystallize the urea within the matrix of the pellet. The result is a substantially harder particle relative to pretreatment hardness, reduced solubility for longer lasting pellets and substantially reduced dust and other handling problems of the formed pellets. |
