METHOD AND DEVICE FOR OBTAINING SULPHUROUS NITROGEN FERTILISER

摘要

The invention relates to a method for producing sulphurous nitrogen fertiliser, said method being characterised in that calcium nitrate is reacted with a sulphurous compound in a mixing device, and the fertiliser is obtained by the granulation of the gypsum-containing suspension formed. The invention also relates to a device for carrying out said method. In this way, a technically simple method for producing sulphurous nitrogen fertiliser can be provided due to the fact that the gypsum-containing suspension formed by the reaction is highly fluid and thus easy to pump, and can be treated in conventional granulation devices. The inventive method can also be carried out without the technically complex separation of precipitated gypsum.
