ABSTRACT:
A process is disclosed for the production of a urea sulfur fertilizer by mixing urea and molten sulfur to obtain a molten mixture and solidifying the molten mixture to obtain a homogeneous, solid, particulate urea sulfur fertilizer wherein the sulfur has particle sizes of smaller than about 100 micron. The process comprises passing molten urea and molten sulfur through a mixing device at a temperature above the melting points to produce a finely divided sulfur dispersed in urea with the molten sulfur added in amounts sufficient to produce said urea sulfur fertilizer, maintaining a pressure drop across said mixing device of at least about 200 kPa to form a homogenized melt of urea sulfur, and solidifying said homogenized melt by prilling or agglomeration.
