How does the disc granulator handle agricultural waste and process fertilizers

 The disc granulator plays an important role in the process of processing fertilizers from agricultural waste, especially in converting animal manure such as chicken manure, cow manure, pig manure, crop residues such as corn stover and straw, and by-products of the food processing industry into controllable release organic fertilizer particles. The manufacturing process of the machine is roughly as follows:

Overview of Process Flow

1. Pre processing

Raw material preparation: Firstly, agricultural waste needs to be preliminarily treated, such as cutting and crushing, to reach the acceptable particle size range of the granulator.

Fermentation: Some raw materials, especially animal feces, require pre fermentation to kill potential pathogens, promote beneficial microbial activity, and improve nutrient availability.

2. Mixing

Mix the fermented raw materials with other components such as mineral supplements, organic matter, binders, etc. to achieve a more balanced distribution of nutrients and improve physical properties.

3. Granulation

Entering the disc granulator: The mixed raw materials are fed into the disc granulator, where the disc is tilted and slowly rotated.

Granulation process: The material at the bottom of the disc slides towards the edge due to gravity and begins to aggregate under the influence of centrifugal force. As it rotates, small particles attract each other in a moist environment and gradually aggregate into larger and denser particles.

Spray/liquid ingredients: To assist in particle formation, water or liquid additives are sometimes sprayed in moderation during this stage to enhance agglomeration effects.

4. Finished product sorting

Screening: After granulation is completed, the particles need to be screened to remove particles that are too small or too large, in order to ensure the consistency of the final product.

Drying and cooling: In order to ensure that the particles are stored for a long time without mold or deterioration, they need to be dried and then cooled to room temperature.

5. Packaging and Storage

Qualified particles that have been screened and cooled will be sent to the packaging line, measured and bagged, sealed and stored for sale or further processing.

Key advantages

Easy to operate: The design of the disc granulator makes it easy to operate and maintain, making it very suitable for small and medium-sized agricultural waste recycling projects.

Strong adaptability: able to handle various types of agricultural waste, including raw materials with different physical and chemical properties.

Low energy consumption: Compared to other granulation technologies, the disc granulator consumes less energy, which is beneficial for reducing production costs.

matters needing attention

Moisture management: Ensure that the humidity of the raw materials is moderate, as too high or too low can affect the granulation effect.

Adhesive application: For difficult to form raw materials, it may be necessary to add adhesives to improve their agglomeration ability.

Maintenance: Regularly inspect and clean equipment, especially nozzles and granulation discs, to prevent blockages and wear.

Through the above process, the disc granulator effectively promotes the recycling of agricultural waste, reducing environmental pollution and improving soil fertility, achieving a win-win situation of ecological and economic benefits.
