Organic Fertilizer Granulation Making Machine: New Type Stirring Tooth Granulator

The new organic fertilizer stirring tooth granulator is an advanced equipment that adopts wet granulation technology. It uses the high-speed rotating mechanical stirring force and the resulting air power to continuously achieve mixing, granulation, spheroidization, and densification of fine powder materials in the machine, and finally form uniform spherical particles. This granulation method breaks through the limitations of traditional organic granulation technology. There is no need to dry and crush the raw materials before granulation. Spherical particles that meet the standards can be processed directly by mixing the ingredients, which greatly reduces energy consumption and production costs.

Compared with traditional granulation equipment, the new stirring tooth granulator has the following significant advantages:

• High granulation rate: sphericity of particles ≥ 0.7, adjustable particle size range 0.3-5mm, granulation rate of more than 90%, and adjustable parameters.
• Energy saving and environmental protection: The allowable range of raw material moisture content is wide (20-40%), and organic matter can be directly granulated after fermentation, eliminating the drying process, and the energy saving effect is significant.
• Strong adaptability: It can process all kinds of organic waste, including livestock and poultry manure, crop straw, sludge, etc., to achieve pure organic granulation.
• Easy operation: The particle size can be flexibly controlled by adjusting the material mixing amount and the spindle speed. The lower the mixing amount and the higher the speed, the smaller the particles, and vice versa.
• Convenient maintenance: The equipment has a reasonable structure design, is sturdy and durable, has a long service life, and is simple for daily maintenance.

Application range

The new organic fertilizer stirring tooth granulator has a wide range of raw material adaptability, can efficiently process various types of organic waste, and realize resource utilization. Its main application raw materials include:

• Livestock and poultry excrement: chicken manure, pig manure, cow manure and other livestock excrement, which can be directly granulated after fermentation treatment.
• Agricultural waste: crop residues such as straw, rice husks, and pomace, which are converted into high-quality organic fertilizer through fermentation.
• Industrial organic by-products: food and pharmaceutical industry by-products such as alcohol grains, monosodium glutamate residues, and drug residues.
• Urban organic waste: organic components such as kitchen waste and garden waste that have been sorted and processed.
• Other organic materials: peat, sludge, lignite, cake fertilizer and other raw materials rich in organic matter.

It is particularly worth mentioning that this equipment is not only suitable for organic fertilizer production, but also can be used in the field of feed processing, such as granulation of mixed feed such as corn flour, bean powder, and grass powder. This versatility greatly improves the return on investment of the equipment and creates more profit possibilities for users.

Complete process flow of organic fertilizer pellet plant: from raw materials to finished products

Establishing a complete organic fertilizer pellet production line requires systematic planning of each process link and equipment selection. An organic fertilizer pellet plant based on an agitator granulator usually includes the following main process flow and equipment composition:

1. Raw material pretreatment

Fermentation equipment: trough compost turner or chain plate compost turner, used for aerobic fermentation and maturation of raw materials.

2. Crushing equipment: semi-wet material crusher, to handle large pieces of raw materials after fermentation.

3. Batching and mixing

Batching system: electronic dynamic batching scale, to accurately control the proportion of various raw materials.

Mixing equipment: double-shaft mixer or horizontal mixer to ensure uniform mixing of materials.

4. Granulation process

Core equipment: agitator granulator, to make the mixed materials into spherical particles.

5. Conveying equipment: belt conveyor, to connect the material flow between each process.

6. Granule drying and cooling treatment

Drying equipment: drum dryer, to reduce the moisture content of the granules (depending on the process requirements).

Cooling equipment: drum cooler to prevent the finished product from caking due to excessively high temperature.

7. Screening equipment: drum screener to separate qualified and unqualified particles.

8. Coating equipment: rotary drum coating machine to improve product appearance quality and anti-caking performance (optional).

9. Packaging and storage

Packaging equipment: an automatic quantitative packaging machine to complete finished product metering and packaging.

Storage system: a well-ventilated warehouse to ensure product storage quality.

For organic fertilizer plants of different sizes, equipment configuration can be flexibly adjusted. Small plants (annual output of less than 10,000 tons) can adopt a simplified process, focusing on fermentation, crushing, mixing, granulation and packaging equipment; medium-sized plants (10,000-50,000 tons) are recommended to be equipped with a complete pre- and post-processing system; large plants (more than 50,000 tons) should consider full-line configuration with a higher degree of automation, and may add secondary fermentation, aging and other processes.
