The working principle of organic fertilizer production line processing agricultural waste

fertilizer granulator Apr 22, 2024

The raw materials for organic fertilizer can be methane residue, agricultural waste, livestock manure, and urban household waste. The investment of transforming waste into wealth is worth it; The entire production line can not only convert different organic wastes into organic fertilizers, but also bring environmental and economic benefits.

The working principle of organic fertilizer production line processing agricultural waste to produce fertilizers:

1. Directly enter the fermentation zone with recycled animal manure and other raw materials. After one fermentation and two aging piles, the odor of livestock and poultry manure is eliminated. At this stage, fermentation strains can be added to decompose the crude fibers in order to meet the particle size requirements for granulation production after crushing. During the fermentation process, the temperature of the raw materials should be strictly controlled to prevent excessive temperature from inhibiting the activity of microorganisms and enzymes. The stacker is widely used for flipping, mixing, and accelerating fermentation of stacks.

2. The fermentation materials that have completed the secondary aging and stacking process can be crushed. Customers can choose a semi wet material crusher, which has a wide range of adaptability to the moisture content of the raw materials.

3. Stirring: After the raw materials are crushed, other nutrients or auxiliary materials are added according to the formula for stirring. During the stirring process, a horizontal or vertical mixer is used to mix the raw materials and additives evenly.

4. Drying: Before granulation, if the moisture content of the raw material exceeds 25%, under certain humidity and particle size conditions, use a drum dryer for drying, and the moisture content should be less than 25%.

5. Granulation: Organic fertilizer granulator is used to granulate raw materials into balls, maintaining microbial activity. The survival rate of microorganisms using this granulator is over 90%.

6. Drying: After granulation, the moisture content of the particles is around 15% -20%, which generally exceeds the target. A drum dryer is needed for drying to facilitate the transportation and storage of fertilizers.

7. Cooling: The dried product enters the cooling machine through a belt conveyor. The drum cooler adopts air cooling products to fully eliminate waste heat and further reduce the moisture content of particles.

8. Screening: The drum screening machine achieves the classification of recycled materials and finished products. The recycled materials are returned to the crusher for further processing, and the finished products are transported to the fertilizer coating machine or directly to the automatic packaging machine.

9. Packaging: The finished product enters the packaging machine through a belt conveyor. The quantitative automatic packaging of finished products is carried out by this packaging machine, which has a wide quantitative range and high accuracy. When combined with a conveyor sewing machine with adjustable tabletop, it has high efficiency and is versatile. Meet the packaging requirements and usage environment of different products.

The fertilizer production line of the organic fertilizer production line mainly includes pre-fermentation and post-granulation, drying and packaging, etc. The npk production line is mainly for mixing, crushing, granulating, screening, drying, etc, granulation and drying are essential for fertilizer production few, common organic fertilizer granulators include: double roller granulator, transfer granulator, disc granulator, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator, ring die granulator, all kinds of granulators have their own production characteristics, and the prices of granulators vary. Today I will explain to you how the organic fertilizer production line dries the particles.

The tube jet dryer is a new type of drying device improved on the basis of the original plate type drum dryer. After the modification, the principle of the device is more scientific, and the drying efficiency is increased by more than 30%. It is mainly used for drying of organic fertilizer production line granules and npk manufacturing process granules.

The round granules with high moisture content from the organic fertilizer granule shaping section are conveyed to the feeder of the tubular jet dryer through the conveyor belt, and the chute in the feeder directly enters the rotating drying drum. With the rotation of the drying drum, the granular organic material is brought to a certain angle. When the main tube of the drying tube and the branch tube of the drying tube are installed, they form a certain angle with the horizontal ground, which coincides with the picked-up material. The picked-up granular material will bury the outlet end of the drying tube branch, so that the granular material can fully Contact with hot air to prevent heat loss. After the particles are heated, hot water vapor will go up to the upper end of the drying drum. Under the action of the high-power induced draft fan for outdoor dust removal and water vapor removal, the water vapor dust, etc. are discharged out of the drying device through the air intake, and finally the dry organic fertilizer granular material with low moisture content is obtained.

fertilizer granulator Apr 22, 2024

The flat mold granulator uses the center of gravity force of the material for feeding, and the material falls onto the template through the center of gravity force. Does this solve the feeding problem of materials with poor fluidity; The flat mold granulator is an open type machine with good heat dissipation, and the rotational speed is not as fast as the ring mold machine, so it can achieve low-temperature granulation and ensure the survival rate of beneficial bacteria (which is very suitable for fermenting feed).

The flat mold granulator also has a very important point, which is that it is suitable for a wide range of raw materials, because the flat mold granulator uses the principle of extrusion, and the particles produced have a certain strength. No matter what raw materials are, other granulation equipment such as cow and sheep manure with high fiber content, mushroom residue, and rice husks that are added to the fermentation and water absorption cannot form raw materials. The flat mold granulator can be extruded into shape, and the extruded finished products are not scattered during transportation, and are easy to melt when they come into contact with water on the ground.

NPK fertilizer is a diversified fertilizer that contains various nutrients such as nitrogen (N), phosphorus (P), and potassium (K), and is one of the commonly used fertilizers in agricultural production. The following is the basic production process of the NPK fertilizer production line:

Raw material preparation: The main raw materials for NPK fertilizers include urea, phosphate, ammonium sulfate, ammonium nitrate, potassium chloride, etc. Before starting the production line, it is necessary to prepare various raw materials and ensure that their quality meets production requirements.

Raw material processing: The raw materials undergo processing steps such as weighing, grinding, and mixing to ensure the proportion and uniformity of various raw materials. In this step, the ratio of various raw materials can be adjusted according to the formula requirements to meet the nutritional requirements of different crops.

Wet mixing: Add the processed raw materials to the fertilizer mixer and mix them evenly through wet mixing. During the mixing process, an appropriate amount of water or solution can be added to improve the fluidity and reactivity of the raw materials.

Granulation: Feed the mixed raw materials into a granulator or fertilizer granulator for granulation treatment. The purpose of granulation is to compress the mixed raw materials into granules for easy transportation, storage, and application.

Drying and cooling: The granulated NPK fertilizer needs to be dried and cooled to remove excess moisture and reduce particle temperature, ensuring product quality and stability.

Screening and packaging: After drying and cooling treatment, NPK fertilizer enters the fertilizer screening machine to remove particles that do not meet the specifications and is packaged. Packaging can choose from bagged, loose or large bags, depending on market demand and customer requirements.

Quality inspection and delivery: Finally, quality inspection is carried out on the produced NPK fertilizer, including appearance, component content, particle size, and other indicators. Qualified products will be packaged and shipped to the market.

The entire production process needs to strictly control the operating parameters of each link to ensure the quality and stability of the product. At the same time, attention should also be paid to environmental and safety requirements to ensure that the production process complies with relevant laws, regulations, and standards.

Dry roller squeezing granulator is a commonly used granulation equipment

fertilizer granulator Apr 18, 2024

Dry granulation mainly relies on the physical force of the machine to process the material. The huge compaction or compression force provided by this mechanism can make the material particles adhere to each other, the agglomeration is stable, and the appearance and fluidity are good. Granular products are suitable for transportation and storage due to the absence of chemical reactions. Common dry organic fertilizer granulators include double roller granulator and flat film granulators, etc. Low-moisture materials can be dry-granulated at room temperature. Dry granulation technology can be used in many places, such as fertilizer granulation, drug granulation, chemical granulation, livestock feed granulation, food granulation, etc. It is widely used and can be used in npk production line, organic fertilizer production line and so on as needed.

So is the dry granulator a universal granulation method? Of course, dry granulation is not a panacea, it has several disadvantages that you should know.

1. You must pre-prepare the material before pelletizing. The material needs to be fully fermented and chopped. In response to this problem, Heavy Industry Machinery has developed corresponding equipment. You can use our fertilizer composters and shredders for the job, which are also reliable and durable.

2. If the dry granulator is not good enough, you will end up with a lot of powder and dust in the process. But if you are using a dry granulator, this will not be a problem anymore. Our careful design will ensure that the process will not cause air pollution.

3. Since dry granulated granular products are made by extrusion or compression by a machine, they are not perfectly round. You can use a fertilizer granule polisher for this to make the granules look nicer and more spherical.
