Organic fertilizer production equipment processes straw manure into organic fertilizer. Fertilizer granulator shapes the physical shape of fertilizer. Organic fertilizer made into granules is easy to store and sow, and improves practicability. According to the different properties of raw materials, we use the corresponding fertilizer granulator. Different fertilizer granulators form different shapes of organic fertilizer particles, such as spherical, elliptical and cylindrical. Here we introduce two kinds of fertilizer granulator which are widely used and suitable for most organic fertilizer production.
This organic fertilizer granulator is specially designed for chicken manure, pig manure, cow manure and other fecal fermentation granulation equipment. It is suitable for crop straw, wine residue, fungus residue, drug residue, animal manure, etc. It also achieves good granulation effect for raw materials such as humic acid and municipal sludge. The new type organic fertilizer granulator has good product shape and spherical particles. The granulation rate of organic fertilizer granulator is more than 90%. The size of particle diameter can be adjusted by the amount of material put into the granulator and the speed of the granulator.
Flat die granulator
Flat die granulator is suitable for fertilizer granulation with more crop straw in fermentation products, and has unique granulation effect on non-mouldable materials. Flat die granulator can granulate material by extrusion, and there is no obvious temperature change in granulation process, so it is also used for granulation of biological bacterial fertilizer. The processing technology of flat die granulator can keep the nutrients in organic fertilizer raw materials well and keep the raw materials in the water for a long time. It is also an important pelletizing equipment for feedstuff processing in aquaculture industry because of the good hardness of the pellets produced by the flat die granulator.
In the production of organic fertilizer, we should compare different granulators, select suitable fertilizer granulators according to the performance of granulators and the characteristics of raw materials used, and improve the processing efficiency of organic fertilizer.
