How to effectively ferment and granulate organic fertilizer raw materials

In recent years, due to the excessive use of chemical fertilizers leading to low resource utilization and intensified environmental pollution, the market for organic fertilizer equipment has gradually opened up. We know that organic fertilizer, as a traditional fertilizer, has incomparable advantages in improving soil. Although fertilizers still dominate the majority of the market, they have shown an overall downward trend, gradually giving way to organic fertilizer products. So how does organic fertilizer equipment produce fertilizers?

The raw materials for organic fertilizer products mostly come from animal manure, which is a traditional fertilizer used in the planting industry. However, it is now being industrialized and commercialized for sale. These raw materials, although belonging to the category of livestock waste, have natural properties and contain a large amount of nutrients. They not only contain basic nitrogen, phosphorus, and potassium, but also contain organic matter, making them nutritious and comprehensive. Especially in the industrial production process, the addition of trace elements or biological strains further enhances the effectiveness of fertilizers.

When it comes to animal manure, the first thing that comes to mind is the continuous odor, sewage flowing horizontally, and the lack of any connection with the organic fertilizer products sold in the market. This also determines that the production of organic fertilizer is a complex process.

The first process of fermentation has a very long time cycle, which requires the cooperation of bacterial strains and organic fertilizer stackers to gradually kill harmful microorganisms in the raw materials, evaporate excess water, and ultimately become odorless and harmless organic fertilizer raw materials.

The fermented material can actually be used for fertilization because it has been thoroughly fermented and will not cause seedling burning or pests and diseases. Considering commercialization, it is necessary to further process the materials, that is, crush and sort them. The large pieces of fertilizer are crushed and easy to bag. If there are impurities inside, they can be screened out by an organic fertilizer screening machine, leaving only the fine and uniform powder. This not only looks good, but also is very convenient to use.

Common organic fertilizer granulators on the market include: roller extrusion granulator, rotary drum granulator, disc granulator machine, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die Granulator, ring die granulator, today we will take you into the double-roll granulator.

The double roller granulator, this equipment can directly compress and granulate powdery materials with water content mellow and less than 5% in the granulation process, and one-time molding, the product can be directly packaged by organic fertilizer packaging machine equipment. It avoids the drying and cooling process after granulation in the traditional organic fertilizer production process. So, how to install and debug the newly purchased dry roll granulator? The working principle of the dry roll granulator is that the material is forced to be compressed into small pieces through the gap between two relatively rotating rolls through external pressure. During the rolling process, the actual density of the material can be increased by 1.5 to 3 times to meet the requirements of the fixed particle strength.

Double roller granulator is granulation equipment, which can be used in organic fertilizer production line, npk fertilizer production line and so on. No waste discharge, stable operation, reliable operation and convenient maintenance. Wide adaptability of raw materials, suitable for granulation of compound fertilizers, pharmaceuticals, chemicals, feed and other raw materials.

The roller extrusion organic fertilizer granulator is an improved product that absorbs the new technology of the international granulator. The machine is equipped with a feeding system connected with a pre-feeder and a forced-feeding screw feeding hopper that is assembled with the machine to ensure the continuity, richness and symmetry of the feeding, which is a crucial step. Uniform arc grooves are engraved on the paired rollers, which is conducive to material biting into the rollers, resulting in arc grooves sealing the cavity (belt), and also conducive to material compaction, reducing the forming pressure of the mechanism and the load of the main machine, and improving the manufacturing rate of the rollers.

Production examples and main equipment of granular potash fertilizer equipment.

Granular potash fertilizer production equipment raw materials: powdered potassium oxide (0-0-60) or powdered potassium sulfate (0-0-50); magnesium chloride, magnesium sulfate, magnesium oxide bitter soil powder: fillers, including clay, bentonite, gypsum, etc. 

(1) Stir and dissolve human water, magnesium oxide (or ferric sulfate), magnesium oxide (or ferric sulfate), and potassium fertilizer production equipment into a solution, then add powdered magnesium oxide in a certain proportion, and stir evenly to form the required magnesium hydroxide hydrate (or sulfate hydrate).

(2) Potassium fertilizer production equipment add powdered potassium chloride or potassium sulfate to a rotary drum granulator or a double roller granulator, and spray wine in proportion. Hydrated magnesium oxychloride (or hydrated magnesium oxysulfide) is a granulation aid, and the addition amount is 0.5%~10.0% by dry weight. At the same time, the potash fertilizer production equipment can continuously granulate into balls through steam, and then dry, cool, and sieve to obtain the finished granular potash fertilizer.

The main equipment for granular potassium fertilizer production is dry powder granulator (double roller granulator), which is mainly equipped with forced eye feeder, rolling unit, frame platform, crusher, multi-stage screening machine, bucket elevator machine, electrical control cabinet. The dry powder granulator has reasonable design, compact structure, simple process and convenient operation. Powder raw materials can be directly processed into uniform particles of 0.5~5mm without any additives, which greatly increases the bulk density of materials, reduces consumption, controls environmental pollution, reduces packaging costs, and improves the working environment for workers. Our organic fertilizer equipment manufacturer specializes in the production of organic fertilizer equipment, including npk fertilizer production line, organic fertilizer production, etc.

Blended fertilizer, also known as BB fertilizer, is a chemical fertilizer that contains any two or three of the three nutrients of nitrogen, phosphorus, and potassium. Blended fertilizer has strong targeting and formula flexibility. Different crops and soil textures can be formulated with targeted fertilizers before application. Reduced the occurrence of nutrient deficiency or excess during the fertilization process.

The shape of mixed fertilizers is mostly granular, and the mixed fertilizer particles are granulated using a pair of roller granulator. The pair of roller granulator is an important equipment for granulating mixed fertilizers, compound fertilizers, and other fertilizers.

Characteristics of the roller extrusion granulator for mixed fertilizer:

1. The roller extrusion granulator can produce fertilizer particles at room temperature without the need for drying.

2. When squeezing and granulating on the roller, the fertilizer is put in from the inlet, and then squeezed by two opposite rotating roller shafts through the ball socket on the roller skin, expelling air and squeezing into granules.

3. The production capacity, particle diameter, and roller ball pressure shape of the roller squeezing granulator can be customized according to customer needs.

The BB fertilizer production line, as a modern solution to improve agricultural efficiency, has advantages such as high-quality fertilizer production, customized production, efficient production processes, and environmental sustainability. Through precise ingredients, mixing, and dissolution processes, efficient nutrient supply can be provided to promote the growth and development of crops. The application prospects of BB fertilizer production line are broad, and it plays an important role in agricultural production, greenhouse planting, and environmentally friendly agriculture. With the development of agricultural modernization, the BB fertilizer production line will play an increasingly important role in agricultural production, contributing to agricultural efficiency and sustainable development.

We purchase organic fertilizer equipment to build organic fertilizer production lines or npk production line. We know that a complete organic fertilizer production line is worth a lot of money. A fertilizer production line equipment usually includes: crusher, feeder, horizontal mixer, rotary drum granulator, dryer, cooler, screening machine, weighing packaging machine . So the maintenance of organic fertilizer production line is very important. Many people do not know this knowledge is very distressing. Next, we’ll explain some tips for maintaining your organic fertilizer equipment.

How to reduce equipment damage in fertilizer production line

    1. One of the factors that are relatively easy to damage organic fertilizer production line or npk fertilizer production line fertilizer equipment is dust. After the organic fertilizer equipment is discharged, it will actually produce a certain amount of dust. If it is not cleaned and maintained in time, dust will enter various joints such as equipment. As time goes by, the greater the friction of the equipment connection, it will even lead to the accumulation of bacteria, which will cause certain erosion to the system and affect the performance of the equipment. Therefore, we require employees to conduct comprehensive inspection and maintenance when using organic fertilizer equipment.

    2. During the operation of organic fertilizer, attention should also be paid to the lubrication level of the equipment connection. Long-term use of equipment is a serious condition for equipment lubrication. Once blocked, the friction of the equipment will also increase. Only in this way can it provide good power support for the operation of organic fertilizer equipment. Employees should form a good habit of cleaning and maintaining equipment on time.

    3. In addition, pay attention to the friction of the motor, otherwise it will affect the application of organic fertilizer equipment, and the staff should always pay attention to check the operation of the motor. Especially before load operation, the wiring of the motor should be checked. If damaged, it should be updated immediately to ensure safe operation.

The organic fertilizer production line, npk production line, and bio-organic fertilizer production line are all composed of different production equipment, so in order to prolong the service life of the equipment and improve production efficiency, it is very important to maintain the equipment. Organic fertilizer equipment must be well maintained in daily use, so as to prolong its service life. Let’s take a look at the maintenance secrets of organic fertilizer production equipment.

1. Keep the workplace clean. After each organic fertilizer equipment experiment is completed, the residual plastic sand inside and outside the granulation leaves and granulation pot should be thoroughly removed, the plastic sand and flying objects scattered or splashed out of the organic fertilizer equipment should be cleaned, and the exposed organic fertilizer equipment processing surface should be wiped. Apply anti-corrosion paint and wear corresponding shields to avoid secondary intrusion of dust.

2. The organic fertilizer equipment has no external oiling holes, and the gears and worm gears are lubricated with special butter for organic fertilizer equipment. The upper and lower gears should be buttered quarterly. When refueling, the gearbox cover and gear shaft cover of the starting group can be opened. The oil should frequently drip into the sliding surface between the gearbox and the bracket.

3. Always pay attention to the operation of the organic fertilizer machine, there should be no serious abnormal noise and dry sound, let alone metal friction sound. If any abnormality is found, the inspection should be stopped immediately, and it can be used only after troubleshooting.

4. Regularly check the standard clearance between the granulation cylinder and the granulator.

5. When maintaining the organic fertilizer granulator (double roller granulator, rotary drum granulator, etc.), when updating the organic fertilizer granulator or granulation leaves, the working gap should be re-measured each time and adjusted several times. It can be used normally only after meeting the requirements.

6. If the organic fertilizer machine cannot operate according to the stroke controller, check the power supply voltage, power plug socket, connection plug socket, etc., and check the internal fault of the controller.

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.
