Ammonia granulation, spraying granulation, high tower granulation ,which is the best
Send Time:2023-2-12
1. The fertilizer granules produced by drum spraying granulation is hard, fertilizer efficiency is longer than high tower granulation, can be used for base fertilizer for long growth period of crop .The disadvantage is that nitrogen is easy to be lost when combining, so there is a secondary nitrogen adding process.
2. High tower granulation particles are smooth, hollow anti-counterfeiting, balanced content, NPK can be freely deployed, fertilizer effect in compound fertilizer is the fastest, easy to dissolve, the most suitable for top dressing. The disadvantage is that when granulating and spraying, urine melting, if the process time is not well controlled, easy to produce a large number of biuret, and is easy to exceed the standard of water in the production.
3. Ammonia granulation is pipe reacting granulation, fertilizer efficiency between the drum granulation and the spraying granulation, the utilization rate is better than the spraying, but lower than the tower granulation, water solubility is good, particles into irregular shape, high nitrogen and potassium content can be adjusted freely, suitable for formula fertilization.
4. The drum granulation process is simple and the granulation is smooth, the fertilizer effect is better than the rotary drum grouting granulation, this method is widely used for most fertilizer factories.
