Author: organic fertilizer production line

NPK fertilizer refers to chemical fertilizers with nitrogen (N), phosphorus (P), and potassium (K) as the main nutrients. Small NPK fertilizer production lines typically involve multiple key steps aimed at mixing and processing these basic ingredients and other auxiliary materials into granular fertilizers that are easy to store and use. The following are the core granulation steps of a small-scale NPK fertilizer production line:

Raw material pretreatment: Firstly, the solid raw material is crushed into fine powder, and NPK and other additives (such as trace elements such as sulfur, magnesium, zinc, etc.) are accurately weighed according to the formula. The liquid composition needs to be measured and kept as a backup.

Mixing: Put powdered NPK components and other solid raw materials into a high-speed mixer to ensure uniform distribution of each component and form a homogeneous mixture.

Granulation: Use a fertilizer granulator to make granules. There are two common ways:

Disc granulation: Wet the mixture with water, pour it into a rotating disc granulator, and use centrifugal force to form spherical particles.

Squeezing granulation: using high pressure to squeeze the mixture through a mold, then cutting it into cylindrical or sheet-like particles of a certain size, and then crushing them into the desired size.

Drying: After granulation, the particles need to enter a dryer to reduce moisture content, prevent clumping, and maintain stable physical properties of the fertilizer.

Cooling: The dried particles will be sent to a cooling tower or cooler for rapid cooling, preventing the quality of fertilizers from being affected by high temperatures.

Screening: The cooled particles are passed through a vibrating screen to remove oversized or undersized non-conforming particles, ensuring the consistency of the product’s particle size.

Coating treatment (optional): To extend the shelf life of fertilizers and enhance moisture resistance, a protective layer such as wax or resin can be applied to the surface of particles.

Packaging: The final step is to weigh, package, label, and prepare the finished product for shipment or storage.

Quality inspection: Strict quality testing should be conducted throughout the entire production process, including before the finished product, to ensure that every bag of NPK fertilizer meets the standards.

Although the small-scale NPK fertilizer production lines is small, each process is indispensable, and precise coordination is necessary to produce high-quality products. Proper operation and maintenance of equipment, optimization of process parameters, are key to ensuring efficient operation of production lines.

The cow manure organic fertilizer production line refers to a series of processes that convert fresh or dry cow manure into high-quality organic fertilizers. This process involves multiple steps aimed at fully utilizing the nutrients in cow manure while removing potential harmful substances, as shown below:

1. Preliminary preparation

Collection and storage: Firstly, collect cow manure, usually fresh or dried cow manure after solid-liquid separation.

Mixed raw materials: If necessary, other organic waste such as straw, sawdust, chicken manure, etc. can be added to adjust the carbon nitrogen ratio for subsequent fermentation.

2. Fermentation pretreatment

Composting fermentation: This is the most critical step, where the mixture is stacked in strips or flipped for fermentation, promoting microbial activity, high-temperature sterilization and disinfection, decomposing organic matter, and generating heat. The temperature can reach 50 ° C to 70 ° C.

Pile flipping ventilation: Regularly flip the pile to ensure sufficient oxygen, accelerate the fermentation process, and avoid adverse reactions under anaerobic conditions.

3. Drying and screening

Drying: The fermented material is dried by air drying or mechanical drying to reduce its moisture content to an appropriate level for storage and granulation.

Screening: Remove large impurities to ensure uniform and consistent particle size in the finished product.

4. Add auxiliary materials and mix well

Microbial agents, mineral elements, or other additives can be added and mixed in specific proportions to enrich the nutritional value of fertilizers.

5. Granulation molding

By squeezing, rotating, and pressing the mixture into particles, it is easy to package and sell.

6. Cooling and packaging

The particles are cooled to prevent excessive moisture and maintain stability.

Finally, use a packaging machine to seal the bags, label them, and prepare for shipment.

7. Quality inspection

Strict quality inspection procedures are implemented throughout the entire process of processing fertilizers on the organic fertilizer production line to ensure that the products meet industry standards and meet customer needs.

The specific process and equipment configuration for each step may vary depending on the production scale, raw material characteristics, and expected output. Modern organic fertilizer production lines typically integrate automated control systems, which improve efficiency, reduce labor costs, and ensure consistent product quality.

The raw materials for processing fertilizers in small-scale organic fertilizer production lines are very extensive, covering almost all types of organic waste in agriculture, animal husbandry, forestry, and daily life. These raw materials can be used individually or mixed and blended according to different needs to prepare organic fertilizers that meet specific soil and crop requirements. Here are some common types of raw materials:

Livestock and poultry manure, such as chicken manure, cow manure, pig manure, sheep manure, etc., are the most commonly used organic fertilizer raw materials, rich in major nutrients such as nitrogen, phosphorus, potassium, and organic matter.

Agricultural by-products, such as straw, wheat straw, corn cobs, soybean meal, molasses, etc., are rich in cellulose and lignin, which help regulate the carbon nitrogen ratio and increase organic matter content.

Forest fruit branches and leaves: fallen leaves, sawdust, tree branch fragments, etc., are also good organic sources that can be used to improve soil structure and provide trace elements.

Kitchen waste: Vegetable residues, fruit peels, coffee grounds, tea leaves and other household kitchen waste, although not in large quantities, are also useful additives in small-scale systems.

Industrial by-products, such as distiller’s grains, soy sauce residue, rice bran, etc., are rich in protein and minerals and are suitable for making composite organic fertilizers.

Urban sludge: Sludge from domestic sewage treatment plants that has been properly treated contains certain organic matter and nutrients, but it needs to be handled carefully to ensure safety.

Herbaceous plants: Green manure plants such as clover, sesbania, ryegrass, etc. can quickly improve soil quality by planting and turning them into the soil or harvesting and fermenting them.

Seaweed: Marine organisms such as kelp and seaweed contain abundant trace elements, especially iodine and magnesium, which are particularly beneficial for certain crops.

These raw materials can be transformed into valuable organic fertilizers in small-scale organic fertilizer production lines through different combinations and processing methods. It is worth noting that before using any raw materials, their safety, especially the content of heavy metals and pathogens, should be evaluated to ensure the quality and safety of the finished fertilizer. Reasonable selection of raw materials and scientific formulas are the key to the success of small-scale organic fertilizer production lines.
