Organic fertilizers are mainly derived from plants and/or animals and are applied to the soil to provide carbonaceous materials whose plant nutrition is its main function. When organic fertilizers are stored for a long time, they will agglomerate and are not conducive to application. So what is the way to prevent organic fertilizer from agglomerating? In order to prevent agglomeration, we should pay attention to the following aspects in the
organic fertilizer manufacturing process.
First, reasonable choice of raw materials, that is, the choice of raw materials that are not easy to agglomerate as raw materials for our production, such as trace element foliar fertilizer, iron, copper, manganese, zinc, sulfate and boric acid, ammonium molybdate as raw materials, additives to Magnesium sulphate is the main material. The main material is relatively dry. When the air is not too humid, the produced fertilizer will not agglomerate. The fertilizer with humic acid as the main raw material and the fertilizer with amino acid as the main raw material are not easy to agglomerate. Also choose the material as dry as possible.
Second, choose the right production time. Since most of China belongs to the North Temperate Zone, the rainy season is mostly concentrated in June, July and August. The higher temperature is also concentrated in this time, so the fertilizer is produced in spring, late autumn and winter. The probability of the block is also lower, which is because the air humidity is small and the temperature is not high, which is not conducive to agglomeration.
Third, add some anti-caking agents, such as talc, humic acid and other powders, which are not easy to agglomerate, they play a bridge in the middle. It is also possible to add some surfactant to prevent agglomeration.
Fourth, it is necessary to take reasonable packaging to prevent extrusion. The packaging materials are mainly used to prevent moisture absorption and ventilation, and prevent excessive extrusion during transportation and storage, and can effectively prevent caking.
Fifth, the granulation technique can prevent agglomeration, and the contact area between the particles and the particles is small, and it is difficult to crystallize and agglomerate. Therefore, using a
fertilizer granulator machine to granulate is a better way to prevent agglomeration if conditions permit.
