摘要： The invention concerns a method for the production of nitrate containing products (fertilizers, technical products) from undercooling melts, wherein a XN—water solution is evaporated up to a content of 50-99.8 weight % XN, where X is one or more selected from Ca, Mg, NH, Na and K, and N means nitrate. The preferred range of XN is 70-99.5 weight %. The melt is cooled down to and kept at a temperature at or below the crystallisation point and finely divided solid XN powder consisting of the equilibrium phases is added to the melt. Melt drops are then formed and allowed to cool and solidify during up to 70 seconds. It is preferred to use a cooling belt for solidification of the particles. The belt is cooled by air, water, oil or another medium.

摘要： The invention relates to a method for making NK-fertilizers basically from calcium nitrate fertilizers and potassium nitrate and homogeneous NK-fertilizer products. Calcium nitrate fertilizer is melted together with potassium nitrate to form a melt or suspension thereof which is particulated to form a homogeneous NK-fertilizer. The calcium nitrate fertilizer and the potassium nitrate are melted at 90-120° C. and then heated to the desired particulation temperature being 160-190° C. for prilling and 90-140° C. for granulation. The components are mixed in ratios giving a melt or suspension comprising 40-14 weight % calcium nitrate, 55-85 weight % potassium nitrate, 0.5-6 weight % water, 0-4 weight % ammonium nitrate and 0-5 weight % magnesium nitrate.

摘要： The present invention relates to NPK-fertilizer manufactured during application of KCl and/or K.sub.2 SO.sub.4 as potassium source and which also contains magnesium in an amount of 0.2-3.0% calculated as MgO and added in the product as MgO, and method for manufacture of this product. The special features of the method is that to an evaporated nitrogen, phosphorous solution 0.2-3.0% reactive MgO and potassium salts are added before prilling or before/during granulation. MgO is preferably added as lightly calcined MgO having an average particle size of 0.2-3.0 mm, and is added in the mixer just before the prilling means. The new product has reduced tendency to swelling and caking.
