Embodiment 1
[0021] Example 1, an attapulgite modified urea ammonium nitrogen fertilizer, specifically sulfur-based nitrogen fertilizer, prepared by mixing the following components by weight percentage: attapulgite powder 20%, urea 25%, ammonium sulfate 50%, urea sulfate 5% %;
[0022] Its preparation method comprises the following steps:
[0023] a. Preparation of attapulgite fine powder: Hand-select attapulgite clay minerals→drying→crushing→grinding→grading to make fine powder of 100 mesh to 150 mesh, with a water content of ≤15%, and the color is off-white or red;
[0024] b. Prepare urea sulfate solution: mix and stir 93% sulfuric acid, urea, and water in a mass ratio of 1:2:0.1, and control the temperature at 40-60°C;
[0025] c. Granulation: Add attapulgite powder, urea, and ammonium sulfate to the granulator in proportion, then atomize and spray the urea sulfate solution onto the surface of the material bed of the granulator, and use a flow meter to control the flow;
[0026] d. A...
Embodiment 2
[0036] Example 2, an attapulgite modified urea ammonium nitrogen fertilizer, specifically chlorine-based nitrogen fertilizer, prepared by mixing the following components by weight percentage: 15%, urea 20%, ammonium chloride 60%, urea sulfate 5%;
[0037] a. Preparation of attapulgite fine powder: Hand-select attapulgite clay minerals→drying→crushing→grinding→grading to make fine powder of 100 mesh to 150 mesh, with a water content of ≤15%, and the color is off-white or red;
[0038] b. Prepare urea sulfate solution: mix and stir 93% sulfuric acid, urea, and water in a mass ratio of 1:2:0.1, and control the temperature at 40-60°C;
[0039] c. Granulation: Add attapulgite powder, urea, and ammonium chloride to the granulator in proportion, then atomize and spray the urea sulfate solution onto the surface of the material bed of the granulator, and use a flow meter to control the flow;
[0040] d. After drying, cooling, sieving, coating and measuring, the prepared granules are pa...
