Example Embodiment
[0011] Example 1
[0012] Utilize ammonium phosphate device 1 to produce ammonium phosphate slurry to obtain ammonium phosphate slurry with neutralization degree of 1.40-1.50, specific gravity of 1.45-1.50, and water weight percentage (the same below) of 25-30%. The dry base material of the slurry contains N: 14.5% with P 2 O 5 : 45.5%; using the additional raw material device, put the potash fertilizer, nitrogen fertilizer, phosphate fertilizer and other fertilizers or elements through the raw material warehouse 2 (2-1 to 2-4, etc.) ) after the measurement, conveyed to the stirring tank 5 through the conveyor 4, and the consumption ratio of potassium sulfate and ammonium sulfate is 2:1 by weight. The raw material is slurried with the added tail water in the stirring tank 5 to a raw material slurry with a concentration of 65-75% by weight (the same below), which is then transported by the raw material slurry pump 6 after being metered, and then added to the ammonium phosphat...

[0015] Example 3
[0016] Utilize the ammonium phosphate device 1 to produce ammonium phosphate slurry to obtain ammonium phosphate slurry with a neutralization degree of 1.40 to 1.50, a specific gravity of 1.45 to 1.50, and a water content of 25 to 30%. The dry base material of the slurry contains N: 14.5% and P 2 O 5 : 45.3%; using the additional raw material device, the potash fertilizer, nitrogen fertilizer, phosphate fertilizer and other fertilizers or elements are respectively passed through the raw material warehouse 2 (2-1 to 2-4, etc.) ) after metering, conveyed to the stirring tank 5 through the conveyor 4, and the raw materials are all potassium sulfate. The raw materials are mixed with the added tail water in the stirring tank 5 to be a raw material slurry with a concentration of 70-75%, and then transported by the raw material slurry pump 6 after being metered, and then added to the mixing tank of the ammonium phosphate slurry and the raw material slurry in propo...
