Chicken Manure Disc Granulator Organic Fertilizer Line

With the rapid development of organic agriculture and the increasing emphasis on environmental protection, the recycling of chicken manure has become a key focus for livestock breeding enterprises and organic fertilizer manufacturers. The chicken manure disc granulator organic fertilizer line is an efficient, environmentally friendly, and cost-effective solution that turns waste chicken manure into high-value organic fertilizer. This article comprehensively introduces the definition, working principle, core advantages, complete configuration, application scenarios, and selection guide of this production line.

What Is a Chicken Manure Disc Granulator Organic Fertilizer Line?

A chicken manure disc granulator organic fertilizer line is an integrated production system that takes chicken manure as the main raw material, with the disc granulator as the core equipment, and completes the entire process from chicken manure pretreatment, fermentation, granulation to finished product packaging. Different from traditional organic fertilizer production methods, this line is designed for large-scale, automated production, which can efficiently handle a large amount of chicken manure, solve the environmental pollution problem caused by chicken manure accumulation, and at the same time produce high-quality organic fertilizer that meets agricultural needs.

Chicken manure is a high-quality organic raw material, containing 2.34% nitrogen, 2.32% phosphorus, 0.83% potassium, and rich organic matter, which are indispensable nutrients for crop growth. However, fresh chicken manure has high moisture content (70%-80%), strong odor, and contains pathogens and eggs, which cannot be directly used as fertilizer. The chicken manure disc granulator organic fertilizer line realizes the harmless treatment and resource utilization of chicken manure through scientific fermentation and granulation processes, turning waste into "black gold" for agriculture.

Core Working Principle of Chicken Manure Disc Granulator Organic Fertilizer Line

The chicken manure disc granulator organic fertilizer line follows a scientific and systematic production process, which is mainly divided into 7 key stages. Each stage is closely connected to ensure the quality, efficiency, and environmental protection of the production process:

1. Chicken Manure Pretreatment

The first step is to pretreat fresh chicken manure to remove impurities and adjust moisture. Fresh chicken manure is first sent to a solid-liquid separator to reduce its moisture content from 70%-80% to 50%-60%, making it suitable for subsequent fermentation. Then, impurities such as stones, feathers, and plastic scraps are removed through a vibrating screen, and the chicken manure is crushed into powder by a semi-wet material crusher to ensure that the particle size meets the fermentation requirements. This stage lays a solid foundation for uniform fermentation and granulation later.

2. Aerobic Fermentation

The pretreated chicken manure is transported to the fermentation tank or fermentation field, and appropriate auxiliary materials (such as straw, plant leaves, weed powder) and fermentation bacteria are added in proportion to adjust the carbon-nitrogen ratio (C/N) to 25:1-30:1. With the help of a compost turner, the chicken manure is regularly turned to ensure sufficient oxygen supply, realizing aerobic fermentation. The fermentation temperature is maintained at 55-70℃ for 7-15 days, which can effectively kill pathogens, eggs, and grass seeds in the chicken manure, eliminate odors, and decompose crude fiber to form mature organic materials. This stage is the key to ensuring the harmlessness and nutrient stability of organic fertilizer.

3. Material Mixing and Modulation

The fermented chicken manure (mature compost) is crushed again to remove caking and ensure uniform particle size (1-2mm). According to the target nutrient requirements of organic fertilizer, an appropriate amount of nitrogen, phosphorus, potassium, and trace elements can be added, and then sent to a double-axis mixer for uniform blending. At the same time, the moisture content of the mixed material is adjusted to 30%-40% (the optimal moisture content for disc granulation) by spraying atomized water or adding dry auxiliary materials (such as talcum powder), ensuring the smooth progress of granulation.

4. Disc Granulation (Core Stage)

The mixed materials are sent to the chicken manure disc granulator, which is the core equipment of the entire production line. The disc granulator is composed of an inclined disc (adjustable angle) and a base. Under the action of centrifugal force, gravity, and friction generated by the rotating disc, the materials roll continuously in the disc. With the assistance of atomized water or a small amount of binder (such as humic acid), the powdered materials gradually agglomerate into spherical granules. The disc's inclination angle (45°-50° stepless adjustment), rotation speed (20-25 rpm), and edge height can be precisely adjusted according to the material characteristics, ensuring a granulation rate of up to 93% and uniform granule size (1-8mm customizable).

5. Drying and Cooling

The wet granules produced by granulation contain a lot of moisture, which is easy to cake during storage and transportation. Therefore, they need to be sent to a rotary dryer to remove moisture. The dryer uses hot air (80-100℃) to dry the granules, reducing the moisture content to below 10%. The dried granules are then sent to a rotary cooler to cool down to around 40℃, which not only ensures the stability of the finished product but also avoids caking caused by high temperature. The waste heat generated by the dryer can be recycled to preheat raw materials, reducing energy consumption by 20% or more.

6. Screening and Coating

After cooling, the granules pass through a multi-layer vibrating screen for grading. Qualified granules (meeting the required size) are sent to a coating machine to spray anti-caking agents or nutrient coatings, which can improve the fluidity, storage performance, and nutrient retention capacity of the finished product. Unqualified granules (too large or too small) are returned to the crusher for reprocessing, realizing zero waste of materials. The exhaust gas generated during the screening process is treated by a cyclone dust collector and a deodorization system to meet environmental emission standards.

7. Automatic Packaging and Storage

The qualified coated granules are transported to the automatic packaging line, where they are quantitatively packaged by automatic packaging machines (with a packaging speed of up to 800 bags per hour), sewn, and palletized by robots. This greatly reduces labor costs and improves packaging efficiency. The finished organic fertilizer is then stored in the finished product warehouse, waiting for delivery. The entire packaging process can be intelligently controlled, ensuring accurate measurement and consistent packaging quality.
