It’s very easy to know that powdery matter is very easy to fly apart. Of course the powder fertilizer in not exceptional. That causing troubles in loading and unloading during transportation. When fertilizing, the powder fertilizer is easy to fly away with the airflow. That not only is harmful to workers’ health, but also will cause air pollution. Otherwise, the particle size of the powder is below 0.1mm. They are very easy to absorb moisture and bond together, that will reduce you a lot of profits. By contrast, the benefits of granulating powder fertilizer into pellets are very obvious.
Because of the mixing, granulating, balling, and densification during granulation, the powder fertilizer will be fertilizer balls with the hardness of 15-20N, the particle sizes of them are between 0.1mm and 20mm. They are much easier to transport and store than powder fertilizer. Furthermore, with fine hardness, the fertilizer pellets have more compact structure. Not easy to be broken greatly reduces the possibility of air pollution. Moreover, powder fertilizer has very little weight and small size. They are easy to stick on the leaves or roots of the plant, and dissolve rapidly, causing damage to the growth of plants. But after pelleting with powder granulator machine, the final granules can attach to the soil precisely and dissolve at more suitable speed than powder fertilizer. The nutrition of fertilizer can be used efficiently.
