How is dust in compound fertilizers tested? Are there any standards?
Could the original poster describe in detail what the dust in the compound fertilizer you mentioned is like? How is this dust measured? It is the dust generated during the production of compound fertilizers (shards from the compound fertilizers themselves? Dust in the production environment? ）? Is it still the dust generated during packaging and transportation? Is it still due to the debris and powder generated during storage, transportation, and repackaging? Is it the compound fertilizer powder that floats into the air during application? It's better to describe the problem clearly.
It refers to the amount of dust in the finished products. In order to improve the visual quality of the products, the company needs to establish such a corporate standard; it’s worth checking whether any other companies have already done this and learning from them.
Describe it in detail. Refers to the ultra-fine particles in the product that can easily cause dust formation?
The standards for your own company, of course, are set by you yourselves. Find a standard sieve; it’s sufficient to set the limit at the particle size below which the debris of that particular size is considered dust.
Now, use a 100-mesh standard sieve for screening, and then weigh it directly to make the calculation. It involves directly testing the dust present in the finished products, including the dust generated during the factory inspection of compound fertilizers; over time, compound fertilizers may become more powdered, resulting in an increased amount of dust compared to before.
Thank you, that’s exactly what I’m doing now. Sorry for the delay in responding.
