METHOD TO PRODUCE GRANULATED FERTILISER Russian patent published in 2013 - IPC C05C9/00

Abstract RU 2484072 C1

FIELD: agriculture.

SUBSTANCE: method for production of a granulated fertiliser, which contains carbamide and elemental sulphur, by means of spraying of carbamide and sulphur in liquid condition to a curtain of loose material in the volume of a rotary drum, besides, spraying is carried out in a drum with blades installed on its inner surface, sulphur melt and melt or solution of carbamide is sprayed simultaneously with two separate non-crossing flares of circular section with diameters that are approximately equal to half of the circumference diameter formed by free ends of the drum blades, besides, spraying of the sulphur melt and melt or solution of carbamide is carried out along the axis of drum rotation in one direction.

EFFECT: invention makes it possible to provide for distribution of sulphur in a volume of a fertiliser granule in finely dispersed condition without preliminary mixing of components.
