DEVICE FOR MIXING AND DISSOLVING SOLID GRANULES IN A LIQUID, IN PARTICULAR FOR PRODUCING NITROPHOSPHATE FERTILISERS |
摘要 |
<p>The invention concerns a device for mixing and dissolving in a liquid (L) solid prills or particles (G) of a substance soluble in said liquid but having a density lower than that of the liquid, and in particular for preparing a sulpho-ureic reagent corroding natural phosphates to produce phosphonitrate fertilisers. The device comprises a vat (2) containing first stirring means (A1) for driving the solid prills towards the vat (2) lower part, and second stirring means (A2) for generating in the reaction mixture a movement for dissolving the prills, in particular a shearing motion.</p> |
