fertilizer production line

The roller squeezing granulator is a commonly used fertilizer granulation equipment, especially suitable for the granulation production of organic and compound fertilizers. The following is a brief introduction to the working principle and granulation process of the roller extrusion granulator:

operational principle

Extrusion molding: The core part of the roller extrusion granulator is composed of a pair of relatively rotating pressure rollers, which have grooves on the surface. When the material is fed between the two rollers, it is compressed to form a strip shape.

Shear cutting: After the extruded strip material passes through the pressure roller, it is usually cut by a fixed or rotating tool to form the required length of particles.

Adjustment control: By adjusting the gap and speed between the pressure rollers, the size and shape of the particles can be controlled.

Granulation process

Raw material preparation: Firstly, suitable raw materials need to be prepared, such as powder of organic fertilizers or mixtures of compound fertilizers.

Moisturizing and mixing: In order to improve the granulation efficiency, the raw materials usually need to be moistened and mixed with an appropriate amount of water and binder to improve their plasticity.

Conveying and feeding: The mixed materials are uniformly fed into the feeding area of the roller squeezing granulator through conveying equipment.

Squeezing: The material is compressed into strips under the high pressure of the pressure roller, and excess water is squeezed out.

Cutting: The extruded strip material is cut or cut into particles of the desired length.

Drying: Newly formed wet particles contain high moisture and require drying treatment through drying equipment to reduce moisture content, improve particle hardness and stability.

Screening and grading: The dried particles are screened through screening equipment to remove particles that do not meet the requirements and ensure product quality.

Cooling: The screened particles usually require further cooling to ensure their stability during storage and transportation.

Packaging: Finally, the qualified granular fertilizer is automatically weighed and packaged before leaving the factory.

The roller extrusion granulator has been widely used in the field of fertilizer granulation due to its advantages of high efficiency, energy saving, and strong adaptability. By optimizing process parameters and equipment maintenance, the production efficiency and product quality of fertilizer particles can be effectively improved.

Powdered organic fertilizer is commonly used to improve soil and provide the nutritional value components required for crop growth. When they enter the soil, they can also be quickly decomposed and release nutrients quickly. Due to the slower absorption rate of powdered solid organic fertilizers, powdered organic fertilizers have a longer storage time than liquid organic fertilizers. The use of organic fertilizers greatly reduces damage to plants themselves and soil environment.

The process flow of producing organic fertilizer from livestock and poultry manure:

1. Raw material ratio: Various animal feces such as chicken manure, pig manure, cow manure, biogas residue, or fermentable and fertilizer effective raw materials are prepared in a certain proportion;

2. Raw material mixing: Mix the prepared raw materials evenly to improve the overall uniform fertilizer efficiency of the fertilizer particles;

3. Raw material granulation: The evenly mixed raw materials are fed into a fertilizer granulator for granulation;

4. Particle drying: Feed the particles made by the granulator into the fertilizer dryer to dry the moisture inside the particles, increase their strength, and facilitate storage;

5. Particle cooling: The temperature of the dried fertilizer particles is too high, making them prone to clumping. After cooling, they are easy to pack, store, and transport;

6. Particle classification: The cooled particles are classified, and the unqualified particles are crushed and re granulated to screen out the qualified products;

7. Finished product coating: Coating qualified products to increase the brightness and roundness of particles;

8. Finished product packaging: Bag the finished product particles and store them in a ventilated place.

The above are the process steps of the organic fertilizer production line for the treatment of livestock and poultry manure. Of course, the specific operation also involves different processes and equipment choices, which need to be adjusted according to the specific site and actual situation. Because the production capacity requirements of each project, the ground processing site, and the configuration of the entire set of organic fertilizer production equipment are not fixed, there are often many different situations, so the specific price depends on the situation. You need to consider factors such as equipment power, production capacity, automation level, and additional functions. For some special equipment or high-end large-scale production lines, the price may be higher. It is recommended that you conduct market research and communicate with multiple suppliers before making a purchase to ensure that you can obtain the most suitable production line for your needs and budget.

Common organic fertilizer granulators include: double roller granulator, stock granulator, disc granulator, new organic fertilizer granulator, etc. The disc granulator is widely used and can be used for npk fertilizer production line , organic fertilizer production, bio-organic fertilizer production line, etc. Today, let’s understand the working principle of the disc granulator.

The organic fertilizer disc granulator machine is a new type of inclined granulation equipment. The granulation rate of this disc granulator machine  is about 90%. The reducer and motor in the machine are transmitted by a flexible belt, which makes the disc granulator start smoothly, slows down the impact force, and improves the service life of our equipment. The bottom of the granulator disc is reinforced with a variety of radiant steel plates, which are firm and durable and not easy to deform. This thickened and heavier base design is relatively firm, does not require anchor bolts to fix, and is relatively stable. When the disc granulator is running, the granulation is uniform and the spheroidization rate is high. Not only does it run smoothly, but the device is sturdy and durable.

How does the organic fertilizer disc granulator machine work? First, the main motor drives the pulley and belt. The pinion gear is driven by the reducer, and the pinion gear is engaged with the large gear fixed on the ground. The large gear is installed on the main shaft on the frame adjustment disc through a special and reasonable design to support the work of the entire granulation disc. After the material enters the granulation disc, the disc granulation equipment continuously rotates the spray device to make the material evenly bonded to form round spherical particles. The upper part of the disc granulation equipment is designed with an automatic cleaning device, which prevents the material from sticking to the wall and improves the service life of the machine. The motor continuously rotates and the material enters continuously, which can not only realize mass production, but also easily meet the needs of continuous work.

The organic fertilizer tank type flipper is a device used for treating and fermenting organic waste. It improves the ventilation conditions of compost and accelerates the fermentation process through flipping action. The slot type tipping machine is particularly suitable for large-scale composting operations, especially in organic fertilizer production lines. The following are some advantages of the slot type flipper for fermenting raw materials:

1. Improve fermentation efficiency: The trough type flipper increases the ventilation of the compost by flipping it, providing sufficient oxygen for microorganisms and accelerating the decomposition rate of organic matter.

2. Uniform fermentation: The flipping machine can mix fresh materials in the compost with already fermented materials, ensuring a uniform fermentation process throughout the entire compost pile.

3. Reduce odor: Due to the fact that the flipping machine can accelerate the decomposition of organic matter, it reduces the production of ammonia and other odor gases, thereby reducing the odor problem during the composting process.

4. Space saving: The slot type tipping machine usually works in a fixed fermentation tank, which saves space and is easy to manage and control.

5. Reduce manpower: The automated flipping process reduces reliance on manpower, lowers labor intensity and production costs.

6. Improve product quality: Through the uniform flipping of the slot flipping machine, more consistent quality organic fertilizers can be produced.

7. Easy to control: The operation of the slot flipping machine is usually relatively simple, making it easy to control the frequency and depth of flipping, and can be adjusted according to the needs of fermentation.

8. Strong adaptability: The flipping machine can handle various organic waste, such as livestock and poultry manure, crop residues, food processing waste, etc., with strong adaptability.

9. Improving soil structure: Fermented organic fertilizers help improve the physical structure of the soil, increase the organic matter content of the soil, and enhance the soil’s water and fertilizer retention capacity.

10. Environmental protection: The use of slot type tipping machines helps to convert organic waste into valuable fertilizers, reducing waste disposal issues and making it an environmentally friendly treatment method.

11. Improve compost maturity: Through the uniform flipping of the flipper, the organic matter in the compost can be more fully decomposed, producing more mature compost.

12. Reduce pathogens and weed seeds: During the high-temperature fermentation process, the flipper helps maintain the high-temperature state of the compost, thereby killing pathogens and weed seeds, ensuring the safe use of organic fertilizers.

The slot flipper is an important part of the organic fertilizer production line. Through its efficient fermentation treatment, it can produce high-quality organic fertilizers and provide support for agricultural production.

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.

1. Keep the workplace clean. After the production of the organic fertilizer equipment is completed, the granulating blades and the residues inside and outside the double roller granulator should be cleaned, the glue sand and splashes scattered or splashed on the organic fertilizer equipment should be cleaned, the mechanically exposed processing surface of the organic fertilizer equipment should be scrubbed, and the anti-corrosion should be brushed. Anti-rust paint, and cover it with a corresponding protective cover to prevent the dust workers from invading again.

2. The organic fertilizer equipment has no external oil holes, gears, and worm gears to be lubricated with special grease for organic fertilizer equipment. The upper and lower gears are added with ternary grease once a quarter, and the gearbox cover and gearbox gear cover can be opened respectively when refueling. The lubricating oil should drip into the sliding surface that supports the hinge joint between the gearbox and the bracket. The worm gear case and bearings have been filled with sufficient transmission grease at the factory. However, the transmission should be cleaned once a year and the protective lubricant replaced.

3. Always pay attention to the operation of chicken manure organic equipment during organic fertilizer production or npk manufacturing process, without serious abnormal noise and dry sound, and without metal friction sound. If there is an exception, close the check. After troubleshooting, it can be used. If no appropriate cause is found, the machine cannot start. If there is a metal friction sound, please check the gap between the organic fertilizer equipment first.

4. Regularly check the standard clearance between organic fertilizer equipment.

5. During the maintenance of organic fertilizer equipment, the working gap should be re-measured every time, and adjusted several times before it can be used normally.

6. If the controller cannot operate the chicken manure organic equipment according to the program, check whether the power supply voltage, power plug socket and connecting plug socket are normal, and check the internal fault of the controller.

The sheep manure processing organic fertilizer production line is an industrial process that converts sheep manure into organic fertilizer. It involves multiple steps to ensure that the final product is both safe and efficient. The following is a typical process flow of an organic fertilizer production line for sheep manure processing:

The semi wet material crusher is widely used in the production process of organic fertilizers, and has a good crushing effect on wet raw materials such as chicken manure and sludge. This crusher greatly shortens the production cycle of organic fertilizer and saves production costs.

3. Mixing treatment

After the raw materials are crushed, they are mixed with other auxiliary materials and stirred evenly before granulation. The dual axis mixer is mainly used for pre adding water and mixing powdered materials. Its spiral blades have multiple angles and can quickly and uniformly mix raw materials regardless of their shape, size, and density.

4. Screening

After cooling, there are still powdery substances in the finished product particles. All powdered materials and unqualified particles can be screened out through a drum screening machine. Then, it is transported by a belt conveyor to a mixer for mixing and granulation. Unqualified large particles need to be crushed before granulation. The semi-finished products are transported to the organic fertilizer coating machine.

5. Packaging

This is the final production process. The fully automatic quantitative packaging machine is an automated packaging machine designed and manufactured specifically for particles of different shapes. The weighing control system meets the requirements of dust and water prevention, and the material box can also be configured according to customer requirements. Suitable for batch packaging of bulk materials, it can automatically weigh, transport, and seal bags.
