Step four: a raw material formula is prepared, as shown in table 2, the sugar cane alcohol fermentation concentrated solution is added as the binder on the basis of taking kaolin as the binder, the sugar cane alcohol fermentation concentrated solution is added in a manner of spraying at the feed end of a disc granulator, the spraying amount is 6%, and the concentration is 65BX °.
Step five: and carrying out production debugging and determining the optimal operation parameters. The main equipment specifications and operating parameters are as follows: (1) the inner diameter of the disc granulator is 3.24m, the edge height is 0.6m, and the rotating speed is 16 r/min; (2) the inner diameter of the granulation and drying integrated machine is 1.85m, the length is 18.5m, the rotating speed is 3.5r/min, and the hot air temperature is 550 ℃.
The balling rate of the fertilizer obtained by the method is improved to 81.5 percent, which is 171.67 percent higher than that of the extrusion granulation process adopted before the improvement; the fertilizer productivity is improved to 9.7t/h, which is 223.33 percent higher than that of the extrusion granulation process adopted before the improvement. The fertilizer obtained by adding the sugarcane alcohol fermentation concentrated solution as the binder has higher utilization rate, better fertilizer efficiency and more obvious crop yield increase.
