Urea Finishing Process: Prilling Versus Granulation

Jan 01, 2015· Results of size distribution of the samples show that the most of the granules fall in the size range between 2.82 and 3.06 mm, whereas the prills size is around 1.65 mm. Strength measurement using side crushing test also shows that the prills with the average failure load of 3.80 N remain significantly weaker than the granules with failure load of 10-17 N. Strength distribution of the particles also shows that a more uniform strength distribution is observed for the prills than the granules.
