Granular organic fertilizer can be spread by machine, which can improve the efficiency of farmers’ farming. Therefore, even if the investment cost of granular organic fertilizer production equipment is high, there are still many organic fertilizer companies willing to produce granular organic fertilizer. However, the problems of low pelletization rate and irregular particles in organic fertilizer granulation also trouble many organic fertilizer companies. Let’s take a look at what factors affect organic fertilizer granulation.
First, Material reason analysis
1. Water. Before organic fertilizer granulation, the material is in powder form. In order to granulate, some water needs to be added to condense. The more water is added, the larger the particles are, and the less water is added, the smaller the particles are. Therefore, it is also a big test for the skills of granulators. The disc granulator has high skill requirements for granulators, while the drum granulator has lower skill requirements for granulators.
2. Material fineness. The finer the material, the rounder the particles. On the contrary, the rougher the material, the more irregular the particles.
3. Is it sticky? The raw materials of organic fertilizer are generally poultry and livestock manure, straw, garden waste, etc., which have poor viscosity. Some strong viscosity fillers such as bentonite can be added.
Two,Analysis of granulators
The selection of granulators is also an important factor affecting the pelletization rate and regularity of particles. Common granulators are mainly disc granulators, roller extrusion granulators, flat die granulators, drum granulators, etc.
1. The particles formed by the disc granulator are round, the regularity is not very good, and the sizes are different. They are generally master batches.
2. The particles formed by the roller extrusion granulator and the flat die granulator are cylindrical. Because the mold is used, the particle size is relatively uniform.
3. The particles processed by the drum granulator are also round, and the size has a lot to do with the added water.
The above is the analysis of the reasons for the low granulation rate of organic fertilizer. If you want to know more about organic fertilizer granulation , please contact Huaqiang Heavy Industry.
