发明名称 particulas de sulfato de amônio peletizadas
摘要 The invention relates to a method for preparing pelletized ammonium sulfate particles, the method comprising—providing ammonium sulfate crystals;—isolating a fraction comprising crystals having an intermediate size from crystals having a small size and from crystals having a large size, thereby obtaining remaining crystals comprised of crystals having small size and crystals having large size; and—pelletizing through a die at least part of the remaining crystals, i.e. at least part of the crystals from which the fraction comprising crystals having the intermediate size have been isolated, thereby forming pelletized ammonium sulfate particles.
