PROCESS FOR PRODUCING FERTILIZER GRANULES |
摘要 |
A process for producing fertilizer granules. A process for producing fertilizer granules containing urea and ammonium sulphate by granulation in a fluidized bed of particles is described. Ammonium sulphate particles are introduced into a fluidized bed and urea is applied to the particles in the fluidized bed by spraying an aqueous urea-containing liquid with a urea concentration of 70-99.9% by weight. Preferably, the aqueous urea solution contains a granulation additive and/or ammonium sulphate. |
