Many powder particles are produced in the drum granulation process for 16-16-16 compound fertilizer
Thread Content
Our workshop uses tubular reactors (sulfuric acid + ammonia) for granulation. The materials added include ammonium chloride, potassium chloride, urea, and monoammonium phosphate. The processing method involves drum granulation followed by two drying and two cooling stages. The problem is that the granulation results are not satisfactory: the powder is heavy, there are few particles, a lot of material needs to be recycled, and the finished products are not round. When producing 15-15-15, the particle quality is very good, with a production rate of 50 tons per shift; however, when producing 16-16-16, the quality is poor, and the production rate drops to only 20-30 tons per shift
Reply to 1# c376523477: “Pelletization in a tubular reactor (sulfuric acid + ammonia gas)” and “drum pelletization” – I’m not sure how pelletization is carried out in these methods
Our workshop uses drum granulation; a tubular reactor is installed inside the granulation cylinder, located 60 centimeters from the feed end of the cylinder. Sulfuric acid and ammonia react inside the inner tube of this tubular reactor. Heat is released during this reaction, and the product obtained is a liquid slurry, which helps to reduce the amount of steam required! Other nutrients are also measured using a batching scale and then conveyed via a belt to the granulation cylinder for granulation!
Please send me your ingredient list; there might be issues with the ratio of the ingredients, with the control of granulation temperature, with the amount of amino acid used in the tubular reactor, as well as factors such as pressure and drying temperature, all of which can have an impact.
I’m sorry; the recipe is a confidential company document
At high concentrations, the yield of the product is low; it’s even more difficult to produce at concentration 51. It’s also possible that an excess amount of amino acid is used, which causes the system to dry out
Reply to 5# c376523477: Isn’t it just a recipe? What’s there to keep secret? Who doesn’t make it? ? If you’re keeping it secret, then why post a thread at all? ? If you have a problem, handle it on your own and keep it confidential! ! Ha
The person on floor 7 said it well. Now some people want to know how others do things, yet they don’t want others to be aware of their own methods. There’s no such logic in the world. From what the original poster says, it seems to be a very large device. The throughput is 50 t/h. That’s amazing; who designed such a large system? How many people are needed?
The regular formula is still kept secret, so why do you keep asking? I’m not sure how to analyze your ingredient details for you; I’m confused
It’s funny – coming here to learn*, to communicate with others, while keeping one’s own information secret. Do I have to pay to answer your questions then? ? ? People like you should not come here anymore… Is it just about skills? 》We’re all working together; why can’t we communicate with each other? . .
