Working Principle of Automatic Small Disc Granulator (Core of the Plant)

The automatic small disc granulator is the core equipment of the plant, and its working principle is scientific and simple, relying on the combined action of mechanical force and material characteristics to complete the granulation process. The entire working process is automatically controlled, ensuring stable and efficient granulation, and the specific steps are as follows:

1. Automatic Feeding

The fermented and crushed organic raw materials (powdered, particle size ≤2mm) are automatically transported to the feeding hopper of the disc granulator through the automatic conveyor. The feeding speed is controlled by the PLC system, which can be adjusted according to the granulation effect, ensuring uniform feeding and avoiding the problem of uneven granulation caused by excessive or insufficient feeding.

2. Automatic Parameter Adjustment

The PLC control system automatically adjusts the disc rotation speed and inclined angle according to the preset parameters and the actual granulation effect. The disc rotates at a speed of 10-30 rpm, and the inclined angle is adjusted between 30°-60° steplessly. Under the action of centrifugal force generated by the rotating disc, the materials move toward the edge of the disc; under the action of gravity, the materials slide downward along the disc surface; the friction between the disc inner wall and the materials, as well as between material particles, makes the materials roll continuously in the disc.

3. Automatic Granule Formation

During the rolling process of the materials, the automatic spray system sprays an appropriate amount of atomized water or binder (if needed) into the disc. The water or binder acts as an adhesive, making the powdered organic raw materials adhere to each other and gradually grow into spherical granules. The size of the granules can be precisely controlled by adjusting the disc rotation speed, inclined angle, and spray amount: increasing the rotation speed or inclined angle will produce smaller granules, while decreasing the speed or angle will produce larger granules (1-8mm customizable). The granulation process is fully automatic, and the operator only needs to observe the granulation effect and make simple adjustments if necessary.

4. Automatic Discharge

When the granules grow to the required size, the combined force of centrifugal force and gravity will make them automatically overflow from the edge of the disc, and the automatic conveyor will transport the wet granules to the dryer for subsequent processing. The entire granulation process is continuous, with high efficiency and stable performance, and the average non-fault operation time can reach more than 800 hours.

Complete Production Process of Automatic Small Disc Granulator Organic Fertilizer Plant

The production process of the automatic small disc granulator organic fertilizer plant is simplified, scientific, and highly automated, with clear division of labor between each link, ensuring efficient and stable production while reducing operation difficulty. It is mainly divided into 7 key stages, which are suitable for small-scale production and easy to popularize:

1. Raw Material Pretreatment (Automatic and Simplified)

The first step is to pretreat the organic raw materials (such as cow manure, crop straw) to remove impurities and adjust moisture. The fresh organic raw materials are first sent to the automatic solid-liquid separator to reduce the moisture content from 60%-70% to 50%-60%, which is suitable for subsequent fermentation. Then, the automatic vibrating screen removes impurities such as stones, plastic scraps, and grass roots, and the automatic semi-wet material crusher crushes the raw materials into powder (particle size ≤2mm). At the same time, the automatic batching system adds an appropriate amount of crop straw or sawdust to adjust the carbon-nitrogen ratio (C/N) to 25:1-30:1, creating optimal conditions for aerobic fermentation.

2. Aerobic Fermentation (Efficient and Automatic)

The pretreated raw materials are automatically transported to the simple fermentation tank, and the automatic fermentation bacteria adding device adds a small amount of fermentation bacteria (such as EM bacteria) to accelerate the fermentation process. The automatic compost turner turns the raw materials 1-2 times a day to ensure sufficient oxygen supply and realize aerobic fermentation. The fermentation temperature is automatically monitored and controlled at 55-70℃, and the fermentation time is 7-15 days, which can effectively kill pathogens, weed seeds, and insect eggs in the raw materials, eliminate odors, and decompose crude fiber to form mature organic materials. This stage adopts automatic temperature monitoring, which avoids the problem of insufficient or excessive fermentation caused by manual operation.

3. Automatic Mixing and Modulation

The fermented mature compost is automatically crushed again to remove caking, and then sent to the automatic double-axis mixer. The automatic batching system adds an appropriate amount of trace elements (such as iron, zinc, boron) according to the target nutrient requirements of organic fertilizer, and the mixer mixes the materials uniformly. At the same time, the automatic spray system sprays atomized water to adjust the moisture content of the mixed materials to 30%-40% — the optimal moisture content for disc granulation, ensuring the smooth progress of granulation.

4. Automatic Disc Granulation (Core Stage)

The mixed materials are automatically transported to the automatic small disc granulator, and the PLC control system adjusts the disc rotation speed, inclined angle, and feeding speed according to the preset parameters. Under the action of centrifugal force, gravity, and friction, the materials roll continuously in the disc, and the automatic spray system sprays an appropriate amount of water to make the materials agglomerate into spherical granules. The granulation rate is as high as 85%-95%, and the granules are uniform in size and smooth in surface. The unqualified granules are automatically returned to the crusher for reprocessing, realizing zero waste of materials.

5. Automatic Drying and Cooling

The wet granules produced by granulation are automatically transported to the automatic rotary dryer. The dryer uses natural gas, coal, or crop straw as fuel, and the temperature is automatically controlled at 80-100℃, reducing the moisture content of the granules to below 10% to prevent caking during storage and transportation. Then, the dried granules are automatically sent to the automatic cooler to cool down to around 40℃, ensuring the stability of the finished product. The waste heat generated by the dryer is reused to preheat the raw materials, further reducing energy consumption.

6. Automatic Screening and Grading

The cooled granules are automatically sent to the automatic multi-layer vibrating screen for grading. The qualified granules (meeting the required size) are automatically transported to the packaging link, and the unqualified granules are automatically returned to the crusher for reprocessing. The screening process is fully automatic, with high efficiency and accurate grading, ensuring the quality of the finished product.

7. Semi-Automatic Packaging

The qualified granules are automatically transported to the semi-automatic packaging machine, which quantitatively packages the granules (25kg/bag or 50kg/bag) according to the preset parameters. The packaging process is simple and efficient, and only 1 operator is needed to assist in sealing and stacking, further reducing labor costs. The packaged finished products are stored in a dry and ventilated place, ready for sale or use.
