Embodiment 1
[0045] Raw material ratio: 360 parts of urea, 145 parts of monoammonium phosphate, and 300 parts of potassium sulfate.
[0046] The specific production process is as follows:
[0047] 1. Measure urea, monoammonium phosphate, and potassium sulfate according to the ratio and then fully stir and mix them in the stirring pot;
[0048] 2. After the above materials are mixed evenly, they are conveyed into the granulator by a belt. A nozzle is installed in front of the granulator to spray steam to make the materials into balls and granulate. The granulation temperature is controlled at 40°C-50°C;
[0049] 3. The preliminary pelletized material enters the first drying drum and the first cooling drum in turn, and the temperature of the first drying outlet is controlled at 60°C-70°C;
[0050] 4. After the first cooling drum is discharged, the material is screened, and the large particles screened out are crushed and put into the granulator for granulation; the semi-finished products ob...
Embodiment 2
[0054] Raw material ratio: 365 parts of urea, 120 parts of monoammonium phosphate, 65 parts of calcium magnesium phosphate fertilizer, 300 parts of potassium sulfate, 15 parts of borax, 8 parts of EDTA chelated iron, 6 parts of EDTA chelated manganese, 7 parts of EDTA chelated zinc, 1 part of ammonium heptamolybdate.
[0055] Concrete production technology is with embodiment 1.
[0056] The obtained product has the specifications of 18-7-15, contains medium and trace elements, and does not contain seaweed extract and seaweed residue.
Embodiment 3
[0058] Raw material ratio: 365 parts of urea, 120 parts of monoammonium phosphate, 65 parts of calcium magnesium phosphate fertilizer, 300 parts of potassium sulfate, 15 parts of borax, 8 parts of EDTA chelated iron, 6 parts of EDTA chelated manganese, 7 parts of EDTA chelated zinc, 1 part of ammonium heptamolybdate, 10 parts of seaweed extract (note: 50 parts of liquid, namely 10 parts of dry basis).
[0059] Concrete production process is the same as embodiment 1 except step 2.
[0060] Step 2: After the above materials are mixed evenly, they are conveyed into the granulator by a belt. Two nozzles are installed at the front of the granulator, one of which sprays a certain amount of seaweed extract calculated according to the proportion, and the other nozzle sprays steam to make the material into a granulator. Ball granulation, the granulation temperature is controlled at 40°C-50°C.
[0061] The obtained product has the specification of 18-7-15, contains medium and trace ele...
