Chicken manure is a commonly used organic fertilizer, which is widely used in agricultural production due to its rich nutritional content and microorganisms. The nutrients in chicken manure mainly include nitrogen, phosphorus, potassium, etc., which play important roles in soil and crop growth. However, if chicken manure is left for too long, its fertilizer efficiency will be significantly reduced, and even lose its utilization value. Therefore, in order to ensure the fertilizer efficiency and quality of chicken manure, it is recommended to process and utilize it as soon as possible after collection and stacking to avoid prolonged storage time. For farmers, a simple composting method can be adopted by mixing chicken manure with other organic substances, promoting decomposition and fermentation through flipping and ventilation, and applying it to the soil as early as possible. For larger scale breeding plants or processing enterprises, more advanced organic fertilizer production line processes and equipment can be adopted, such as flippers, fermentation tanks, crushers, screening machines, etc., to improve the efficiency and quality of chicken manure treatment.

The complete set of chicken manure organic fertilizer production equipment includes the following parts:

1. Discharge system: used to transport raw materials (such as animal manure, straw, etc.) from the storage pile to the equipment for the next processing step.

2. Crushing system: Use an organic fertilizer crusher to preliminarily crush the raw materials, making them easy for subsequent processing and fermentation.

3. Mixing system: Mixing different types of raw materials to achieve optimal fermentation conditions, usually requiring the use of weighing equipment to control the proportion of each raw material.

4. Fermentation system: The mixed raw materials are fermented in a fermentation tank, usually requiring control of temperature, humidity and other parameters to accelerate the fermentation process.

5. Flipping system: The fermented organic fertilizer is flipped using an organic fertilizer flipping machine to increase aeration and improve fermentation efficiency.

6. Drying system: Used to dry organic fertilizers that have already been fermented, usually using equipment such as rotary dryers or belt dryers.

7. Packaging system: Packaging dried organic fertilizers for sale or storage.

The above is the main equipment involved in a basic organic fertilizer production process. The specific types and scales of equipment can be selected and customized according to actual needs.

 The 100,000-ton NPK compound fertilizer production line meets the needs of most customers. It is a large-capacity production line. We choose the rotary drum granulator as the main fertilizer making equipment, which is an ideal equipment for large-scale production of high- and low-concentration compound fertilizers. The double roller granulator can be used in small npk production line granulator.

The npk manufacturing process, the compound fertilizer production system has low requirements on formula. The steam with a pressure of 4-6kpa is passed into the drum granulator, mixed with powdered phosphorus, potassium or other nitrogen-containing fertilizers and conditioners, and further granulated. The steam melts the surface of the N, allowing the N to combine with other raw materials. This compound fertilizer production line is especially suitable for high nitrogen compound fertilizer. Various fertilizers can be produced in concentrations ranging from 25% to 48%. Since the moisture content of the material is 3-5% during granulation, the drying capacity is increased by 20%-40%, which greatly increases the fertilizer output and reduces the consumption.

100,000 tons of npk production line process The entire compound fertilizer production process: raw material batching, raw material mixing, granulation process, drying process, cooling process, screening process, coating process, packaging process.

Raw material mixing and granulation:

Mix the raw materials evenly to increase the nutrient content of the granular fertilizer. After mixing evenly, the raw materials are transported to the drum granulator for granulation, and steam and gaseous ammonia are introduced, or orthophosphoric acid, ammonium phosphate slurry, nitrogen solution, and calcium carbonate slurry are added, and a series of chemical reactions occur in the drum . A small amount of water can be added throughout the production process. The drum rotates, and the raw materials are condensed into fertilizer granules under specific temperature and humidity. This is the whole NPK fertilizer granulation process.

Drying and cooling of fertilizer granules:

The ammonia phosphorus potassium fertilizer is sent to the tumble dryer to dry out the moisture in the fertilizer granules and improve the strength of the fertilizer. After drying, due to the high temperature, the fertilizer is easy to agglomerate, so the NPK granular fertilizer needs to be cooled for storage and transportation. We chose the drum cooler because of its high efficiency and high output per hour.
