The whole organic fertilizer granulation equipment is used to process the fermented organic fertilizer into granules, which is more convenient for storage, transportation, and use. The following is the basic process flow of organic fertilizer granulation:
technological process
Raw material preparation: Firstly, it is necessary to prepare organic fertilizer raw materials that have been fermented and properly dried. The moisture content of the raw materials should be controlled within a certain range, as being too high or too low can affect the granulation effect.
Preliminary crushing: If the organic fertilizer particles after fermentation are large or have clumping, they may need to be pre treated with an organic fertilizer crusher to be evenly crushed for subsequent granulation.
Ingredients: According to the formula requirements, it is sometimes necessary to mix different types of organic fertilizers in proportion, add an appropriate amount of binder (such as bentonite), and additives (such as trace elements) to improve the physicochemical properties of the fertilizers.
Granulation: This is the core process of the entire process, which forces the powdered organic fertilizer into shape through equipment such as drum granulators, disc granulators, or extrusion granulators. Among them, the drum granulation method is the most commonly used, which uses a rotating drum to drive the raw materials to roll and form spherical particles.
Drying: After granulation, the fertilizer also needs to go through a dryer to remove excess moisture, in order to prevent deformation or adhesion of the particles during storage and transportation.
Screening: After drying, the fertilizer is separated into particles that do not meet the size requirements through a vibrating screen for secondary granulation or recycling as powder.
Cooling: In order to prevent the fertilizer from deteriorating due to internal heat accumulation during storage, the cooler will lower the temperature of the fertilizer particles to a safe range.
Packaging: The final step is to weigh and package the qualified organic fertilizer particles for storage and sale.
matters needing attention
The entire process should strictly control the moisture content of raw materials and products to avoid being too high or too low, so as not to affect product quality.
The amount of additives and adhesives used should be moderate, too much may lead to difficulty in granulation, and too little may make it difficult to form strong particles.
The selection and operation of equipment must be adjusted according to specific fertilizer characteristics and production needs to ensure optimal results.
Operators should receive professional training, be familiar with the safety operating procedures of the equipment, regularly maintain and clean the equipment, and ensure production continuity and efficiency.
Through the above process, the organic fertilizer granulator can process fermented organic fertilizers into standard granules, which not only facilitates agricultural applications but also increases the commercial value of fertilizers, promoting the sustainable and healthy development of organic agriculture.
