Knowledge related to compound fertilizer granulation

I would like to ask how to increase the hardness of compound fertilizer pellets in the compound fertilizer granulation process What is it all related to? Thank you
Let’s talk about the factors affecting drum ammoniation granulation: firstly, it is directly related to the formula; secondly, it is related to the granulation techniques used. When the formula remains constant, efforts should be made to increase the ammonia flow rate to facilitate the ammonolysis of the free acids on the particle surface ； Increase the speed of the granulator in order to enhance the shear force on the particles ； Increase the exhaust volume of the granulation exhaust fan. In short, there are many influencing factors, and continuous exploration is needed!
We still don’t have a good solution to this problem; at present, adjusting the size of the granulation area in the granulator helps to address it to some extent. The raw materials are crucial; the ratio between sandy substances and sticky substances needs to be continuously adjusted, and there are significant differences among various manufacturers!
In fact, there are many factors that affect particle hardness. Here I’ll share my practical experience; it may not be comprehensive, and I hope everyone will feel free to point out any mistakes so that they can be corrected. The main factors include: 1. The ingredients used, which play a key and decisive role; 2. The structure of the granulator; 3. The method of granulation employed; 4. Temperature control in the dryer; 5. Air flow volume. All of these are factors that influence particle hardness. I believe that with proper experimentation during production, it’s possible to get good control over these aspects. Since each system is different, the specific parameters also vary
Sandy materials are directly related to hardness. The granulation time is longer elsewhere. Lower moisture level. A little more clay will do. But be very careful. It’s too hard. It can’t be transformed in the fields. We’re going to have arguments again. I’m here to talk about sadness. After finally solving problems such as caking and an uneven surface, I was then asked to deal with the issue of it not being soluble. Never mind, I’ll just post such a thread myself to see if anyone else has encountered it.
The poster should provide a granulation scheme; the formula used in the pelletization method plays a crucial role. Different formulas in the slurry method result in varying hardness levels, and even with the same formula, different adjustment methods can lead to differences in hardness
With drum granulation, the particles produced aren’t very round or smooth, which is frustrating. I wonder, dear brother on floor 5, how can this issue of lack of smoothness be resolved? Thank you for the advice
Is the processing method upstairs mainly based on drum granulation, or something else? What is the desired content level?
The products upstairs don’t dissolve well – could this be related to the raw materials you use or the anti-caking agents? What is the moisture content of your products? It’s hard to determine just by hearing from you; this is for reference only
