Why should organic fertilizer be granulated?
2020-01-03
Conventional fertilizers are divided into two types: powdery and granular, but the proportion of granular fertilizers is relatively large. Why is this? Why should granulation be carried out during the organic fertilizer manufacturing process?
This is because the granular fertilizer has no dust pollution during the handling process, and also avoids unnecessary losses, which meets the requirements of environmentally friendly production of organic fertilizer. Compared with ordinary powdery organic fertilizers, granular organic fertilizers are suitable for long-distance transportation, and no separation phenomenon occurs, and the nutrient content is evenly distributed. At the same time, granular organic fertilizers are more suitable for the needs of mechanized fertilization. Therefore, farmers apply fertilizers habitually. The higher the commercial performance of organic fertilizers, the greater their economic value and their competitiveness.
In the production of organic fertilizers using granulators, the material is required to have a certain viscosity. Some raw materials are loose after fermentation. If it is not easy to pellet, it is necessary to add some water or a binder to increase the viscosity of the material. Today, the organic fertilizer granulator manufacturers mainly introduce to you: Which organic fertilizer granulator machine can be used when using pig manure to produce organic fertilizer?
1. Wet granulation machine adopts wet granulation. The moisture content can be as high as 30% ~ 40%. The materials after fermentation can be granulated directly without the need of other processes. At the same time, granulation by mechanical friction, the strength of the particles is relatively large, and the drying process can be omitted in the later stage, which saves the investment cost of organic fertilizer equipment.
2. The new two-in-one granulator has a moisture content of 30% to 40%. It is a combination of agitator granulator and drum granulator. This machine has uniform granulation particle size, and the yield can reach more than 97%. It is very suitable granulation equipment for organic-inorganic compound fertilizer, organic fertilizer and biological organic fertilizer.
Due to the peculiarity of raw material fiber, the drum pelletizer has a low ball forming rate. The agitator pelletizer cannot produce materials with nitrogen content exceeding 8% (easy to stick to the wall). It can produce both organic fertilizer and organic-inorganic compound fertilizer.
3. Other organic fertilizer granulation equipment: disk granulator, water or binder will be added during the granulation process to ensure the material can be granulated smoothly. The double-roll extrusion granulator is produced by non-drying normal temperature process, which is suitable for granulating materials with relatively low viscosity or relatively low water content.
