Clumping of powdered monoammonium phosphate
Thread Content
The clumping of the ammonium phosphate we produce is severe, which affects sales. We use stone dust as a anti-clumping agent, but the market responds negatively to the fact that the compound fertilizers do not form proper granules. I seek help from all experts in this field. Our products are available in 55% and 58% specifications; the moisture content of the finished product is 1.5%, and the packaging temperature is around 45 degrees.
Clumping of powder P is a quite normal issue. To be honest, there aren’t many solutions if this problem occurs. Generally speaking, the higher the moisture level and the higher the temperature during packaging, the greater the likelihood of clumping, but it seems like there shouldn’t be any problems with your case. The fundamental solution is to avoid scattering the material; after storage, it should be packed. A disperser should be used before packing. Of course, the current approach is to keep the stack not too high, in order to prevent heavy pressure from leading to caking. Another measure is to lower the temperature during packing. Using anti-caking agents is not a scientific approach – after all, how can they be used for granulation?
Thank you. We have visited several factories for inspections, and it seems that the production conditions are more or less the same in those factories; however, the problem of caking is not as severe there. In particular, Anhui Sierte performs better in this regard. Therefore, we want to look for the reasons in the production processes. Everyone is welcome to participate in the discussion.
This problem is easy to solve; there should be several solutions.
To prevent fertilizer caking, fertilizer anti-caking agents can be used. Try it and see the effect.
Product caking: 1. Product packaging temperature; 2. Product moisture content; 3. Packaging and storage methods; 4. The neutralization degree of the product should be above 1.0; 5. High impurity content in phosphate ore
At present, we have successfully resolved the caking issue of powdered monoammonium
Keep the moisture content of the finished ammonium carbonate powder at 0.45%-0.70%； Additionally, installing blower cooling equipment at the powder tower outlet can prevent caking.
Our company offers the KQ-102 anti-caking agent specifically designed for ammonium phosphate, as well as granulation aids for compound fertilizers; QQ number: 290238853
The simplest way to prevent clumping of powdered ammonium is to control the packaging temperature and moisture level. It is also important to manage various factors such as the impurity content in the mineral, the degree of neutralization, and the atomization pressure. Additionally, the material can be stored in a loose form before being packaged.
