The advantages of powdery organic fertilizer

Powdery organic fertilizer is the organic fertilizer without granulation and drying, which occupies the absolute main market share. Compared with granular bio organic fertilizer, powdered organic fertilizer has the advantages of small investment, low production cost, less nutrient loss in the process of processing, low price and less ecological pollution, which is generally accepted by planting parks and fruit and vegetable bases. However, the powdered organic fertilizer has not been treated by disc granulator, and its shape is not beautiful enough, so it is not suitable for machine seeding and application.

Powder organic fertilizer production equipment

The production of powdery organic fertilizer is relatively simple. The main production machines are the following five parts: organic fertilizer turner, forklift, ration feeder, pulverizer, and screening machine (drum screener machine or vibrating screener).

Equipment and equipment need to be connected by belt conveyor to form a complete organic fertilizer production line

1. A belt conveyor above the crusher is connected to the large pieces of raw materials that have been screened.

2. A belt conveyor above the screening machine connects the fermentation raw materials.

3. A belt conveyor below the sieving machine connects the sieved finished material, and sends the finished material to the processing site for weighing and packaging.

4. The warehouse needs a conveyor for loading.

How much does the complete set of equipment for producing organic fertilizers cost?

fertilizer granulator May 11, 2024

The price of a set of organic fertilizer production equipment generally ranges from 200000 to 10 million yuan, and the specific price depends on factors such as the type, scale, technology, equipment quality, and brand of the fertilizer. At the same time, it is also necessary to consider transportation costs, installation costs, after-sales service costs, etc. Therefore, when purchasing organic fertilizer production equipment, one should choose appropriate equipment based on their own needs and budget, and comprehensively consider various factors to achieve the best economic and usage benefits.

1. The type of fertilizer is an important factor affecting the price of organic fertilizer production equipment.

Different types of fertilizers require different raw materials and production processes, so equipment prices may also vary. For example, the production equipment prices for organic fertilizers and bio organic fertilizers are generally higher because they require more raw materials and more complex production processes. The production equipment price of organic-inorganic compound fertilizer is relatively low because its production process is relatively simple, only requiring the mixing of organic and inorganic materials for granulation.

2. Scale is also one of the factors affecting the price of organic fertilizer production equipment.

Larger scale equipment requires larger venues, more workers, and more equipment, so prices are usually higher. Smaller devices are relatively cheaper, but their production is also relatively low.

3. The quality of technology and equipment is also a factor that affects prices.

Powder organic fertilizer processing equipment: flipping machine (used for composting process) – vertical crusher (crushing larger blocks in organic fertilizer) – screening machine (screening out non compliant organic fertilizers and returning them) – batching machine (adding other required nutrients to organic fertilizer in a certain proportion, which is an optional device) – horizontal mixer (mixing different materials evenly and using it in combination with batching machine) – single bucket packaging machine (used for quantitative packaging of finished organic fertilizer)

Granular organic fertilizer processing equipment: tipping machine – vertical crusher – drum screening machine (optional here) – batching machine and horizontal mixer (used in combination, belonging to optional equipment) – disc granulator – dryer and cooling machine – drum screening machine – round throwing machine (optional) – wrapping machine (optional) – single bucket packaging machine.

Different processes and equipment quality can lead to differences in production efficiency, product quality, and equipment lifespan. Therefore, equipment with higher prices usually adopts more advanced processes and high-quality materials to ensure production efficiency and product quality.

Improving physical properties: Granular organic fertilizers have better physical properties, such as fluidity, anti caking, and storage stability.

Improving application efficiency: Granular fertilizers can be directly applied to the soil through mechanical fertilization equipment, improving the efficiency and uniformity of fertilization.

Controlled release: The dissolution and nutrient release rate of granular fertilizers are usually slower than that of powdered fertilizers, which helps plants absorb nutrients more evenly.

Easy to store and transport: Granular fertilizers have a small volume, large weight, and are not easily scattered, making them easy to transport and store over long distances.

Improving market value: Granular organic fertilizers have a cleaner appearance, are easier to measure and sell, and enhance the product’s market competitiveness.

Reducing environmental pollution: Through granulation, the loss of fertilizers during storage and transportation can be reduced, reducing environmental pollution.

Adjusting moisture content: During the granulation process, the humidity of the finished product can be controlled by adjusting the moisture content of the raw materials to meet the requirements of subsequent processes.

Adding slow-release materials: During the granulation process, slow-release materials such as sulfur coatings can be added to organic fertilizers to control the rate of nutrient release.

Improving the consistency and uniformity of fertilizers: The granulator ensures consistency in the size and shape of fertilizer particles for each batch, improving the uniformity of fertilizers.

Enhancing the functionality of fertilizers: During the granulation process, other functional substances such as microbial agents, growth regulators, etc. can be added to organic fertilizers to enhance their functionality.

Meeting specific application requirements: Some specific agricultural applications may require granular fertilizers of specific sizes or shapes, and the granulator can be adjusted according to these requirements.

The role of fertilizer granulator in organic fertilizer production line is not limited to changes in physical form, but also includes improvement of fertilizer performance and expansion of fertilizer function. It is an indispensable key equipment in the organic fertilizer production process.

Production process of organic fertilizer for manure treatment in livestock and poultry farms

Process flow of organic fertilizer production line for manure treatment in livestock and poultry farms

In livestock and poultry farms, manure treatment is a crucial step, and the production of organic fertilizer is one of the important methods for converting these manure into valuable resources. The process flow is mainly divided into four steps: collection, separation, composting, and fermentation.

The first stage is the collection phase, where livestock and poultry manure is effectively collected and preliminarily separated. It is possible to separate livestock and poultry manure from urine through a centralized collection and separation system to reduce the generation of ammonia and odor, and improve subsequent treatment efficiency.

Then comes the composting stage, where the separated animal manure is sealed and stored, and organic waste is properly organized and stacked, supplemented by ventilation equipment to control temperature, humidity, and oxygen supply, accelerating the decomposition process of organic matter. During this process, it is important to maintain appropriate humidity and ventilation to avoid the generation of odors and harmful gases.

Finally, in the fermentation stage, after the completion of composting, the compost is subjected to secondary composting fermentation to further enhance the stability and efficiency of the fertilizer. This process requires attention to reasonable moisture control and temperature regulation to ensure the full decomposition of organic matter and the killing of harmful microorganisms.

Organic fertilizer provides organic matter to the soil, thereby providing the necessary nutrients for plants and helping to establish a healthy soil system, rather than destroying it. Therefore, organic fertilizers contain huge business opportunities, and with the gradual restrictions and prohibitions on the use of fertilizers by most countries and relevant departments, the production of organic fertilizers will become a huge business opportunity.

Most organic raw materials can be fermented into organic compost. In fact, after crushing and screening, organic fertilizer compost becomes high-quality and saleable powdered organic fertilizer.
