This granular fertiliser is a mixture of ammonium nitrate and lime. It is sold under various trade names. Because of the calcium carbonate present it does not cause acidity when added to the soil. • Urea (46% N). This is the most concentrated solid nitrogen fertiliser and it is marketed in the prilled form. It is sometimes used for aerial top-dressing.

Urea Granular & Prilled - Royal Global Energy

Solid urea is the largest nitrogen fertilizer product which is produced in two forms of granules and prills. Although the chemical properties of both prills and granules remain similar, their different physical and mechanical properties are distinguishable and make them suitable for different application either as fertilizer or raw materials for chemical industry.

Urea Finishing Process: Prilling versus Granulation

Results of size distribution of the samples show that the most of the granules fall in the size range between 2.40 and 3.50 mm, whereas the prills size is around 1.60 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.

US5378259A - Process for granulating ammonium nitrate

The invention relates to a process for granulating ammonium nitrate fertilizer with a nitrogen content of between 25% and 34% by weight, by forming a mix of NH 4 NO 3 , limestone and/or dolomite, ammonium sulphate and/or ammonium phosphates and MgSO 4 , this latter being added in any one of its crystalline forms and its various degrees of hydration, then granulating or prilling, and cooling.

What is Prilled Urea and how it is different from Granular

Dec 29, 2011· Granular urea is chemically the same as prilled urea. Granular urea, however, is slightly larger and harder. Today, the use of prilled urea is more prevalent because it is more resistant to breaking down when being blended with the other components of fertiliser.

Prilling - an overview ScienceDirect Topics

Droplets are formed under a defined vibration frequency perturbation that sequences the droplets with a fixed diameter. As a result, the perfect spherical beads have a similar diameter chosen from 600 to 2000 μm Broadly speaking, all these cryogenic prilling techniques (cooling by contact with gaseous nitrogen or with liquid nitrogen, prilling monodispersed or not) produce beads or

Difference between Prilling and Granulation

In prilling, the droplet is formed and then solidified. Due to the density difference of the liquid and solid-state a small cavity is created. The layer built up in granulation prevents this for granules [5]. Product Purity. Prilling is a process where melt in is melt out, leading to a product with the highest purity. For a granulation process
