Problems solved by technology

[0003] While the production of compound fertilizer is developing rapidly, the granulation process of compound fertilizer basically follows the traditional method without major improvement. Basically, it is water plus steam granulation, spray granulation, high-tower melting granulation, etc., all of which consume a lot of energy. energy, and the granulation effect of some proportioned fertilizers is poor, and the overall production cost is high, which is not conducive to survival in the competition, and does not conform to the low-carbon development trend of the compound fertilizer industry

Abstract

The invention discloses a granulation binder of compound fertilizer and an application method thereof. The application method of the granulation liquid binder is characterized by: using industrial aluminum sulfate or sulfuric acid to prepare a 5-10 % solution, and using soluble silicate to prepare a 5-10 % solution; uniformly mixing production raw materials of the compound fertilizer according to the proportions of the formula, conveying the mixed materials to a disc granulator or a drum granulator, spraying the two solutions as a granulation liquid phase according to a ratio of 1:2-3 by using different nozzles, wherein, the total spray volume is 5-8 % of the total amount of the compound fertilizer materials; carrying out reaction on the two binders to generate a cement, carrying out bonding, rolling, and granulation on the compound fertilizer materials, and then drying and sieving to obtain a compound fertilizer product. According to the invention, the cost of the binder is low, the operation process is simple, the granulation process can be simplified, the ball-forming effect is good, the strength of the particles is large, and the reverting ratio is low.

Description

1: Technical field [0001] The invention relates to a compound fertilizer granulation binder and a use method thereof, and discloses a compound fertilizer production granulation binder and a use method thereof. Two: background technology [0002] Since the 1980s, compound fertilizers have gradually started in China. In the mid-1990s, the compound fertilizer industry entered a period of rapid development. Since 2000, compound fertilizer projects have been launched across the country, and the industry has developed rapidly. The number of factories may have exceeded 5,000, making the already surplus compound fertilizer industry more competitive. [0003] While the production of compound fertilizer is developing rapidly, the granulation process of compound fertilizer basically follows the traditional method without major improvement. Basically, it is water plus steam granulation, spray granulation, high-tower melting granulation, etc., all of which consume a lot of energy. Energ...
