The use of livestock manure to produce organic fertilizer is a more effective way of harmless treatment and resource utilization for large-scale pig farms. The organic fertilizer npk fertilizer production line is fermentation, crushing, stirring, granulation, drying, cooling, coating and packaging. If there is no organic fertilizer dryer or organic fertilizer coating machine, it can be packaged and stored or sold after cooling after granulation. In addition to the unnecessary granulation process of powder fertilizer, other processes are similar.

In the organic fertilizer npk manufacturing process, the organic fertilizer equipment for producing granular fertilizers requires organic fertilizer granulation equipment. The granulation of mixed fertilizers is an important process in the dry powder granulation process, which is not only related to the internal and external quality of the product, At the same time, it is related to the size of the output and the level of cost, and the granulation production process is not only related to the physical and chemical properties of the material itself, but also closely related to the form and mechanical properties of the granulation equipment. The main types of granulation equipment are disc granulator machine, drum granulator, twin-shaft granulator, double roller granulator and spray granulator dryer. Usually, drying is also required to make the fertilizer water and reach the national fertilizer standard, so as to meet the requirements of storage, transportation and application. At the same time, cooling equipment must be set up in actual production, and ventilation measures must be taken to force cooling.

The investment in organic fertilizer is not only in equipment, but also in site and infrastructure. Therefore, the investment in organic fertilizers ranges from tens of thousands to hundreds of thousands. The simple configuration of organic fertilizer equipment includes: fermentation equipment, organic fertilizer pulverizer, horizontal mixer, organic fertilizer granulator, drum screening machine and quantitative packaging scale.

Equipment configuration and process flow of livestock manure granular organic fertilizer production line

The annual production line of 50000 tons of granular organic fertilizer mainly includes fermentation equipment, granulation equipment, and screening equipment.

Fermentation equipment

Fermentation is one of the key links in the production of granular organic fertilizers, and the main equipment includes a fermentation tank and a tipping machine. The fermentation tank is used to store materials for aerobic fermentation. The tipping machine is used to flip materials during the fermentation process, allowing them to come into full contact with air and accelerate the fermentation process.

Granulation equipment

Granulation equipment is the core equipment for the production of granular organic fertilizers, mainly divided into two types: disc granulator and agitator toothed granulator. The disc granulator uses a high-speed rotating disc to knead the fermented material into granules. The stirring teeth granulator uses the stirring teeth to force the material into particles, which has higher production efficiency.

Screening equipment

The screening equipment is used to screen the particles after granulation, and the main equipment includes a vibrating screen and a flat screen. The vibrating screen separates materials with different particle sizes through vibration, while the flat screen separates particles from unqualified products by swinging back and forth.

The main process flow of the granular organic fertilizer production line includes three stages: fermentation, granulation, and screening.

Fermentation process

The quality of the fermentation process directly affects the quality of the granular organic fertilizer. In this process, the raw materials are added to the fermentation tank, and through the irregular flipping of the stacker, the raw materials are fully in contact with oxygen for rapid fermentation. The fermentation time is generally 7-10 days.

Granulation process

The fermented material is fed into the granulation equipment and made into granules through a disc granulator or a toothed granulator. In this process, the size and shape of particles can be controlled by adjusting device parameters. After the granulation process is completed, the embryonic form of granular organic fertilizer has been formed.

Screening process

The screening process is the final and crucial step in the production process. The vibrating screen and flat screen will screen the particles after granulation, separating qualified particles from unqualified particles and impurities. In this process, it is necessary to select the appropriate mesh size according to the product requirements to ensure product quality.

The price and equipment configuration of organic fertilizer production equipment for cow manure

The pollution generated by animal husbandry has become the main source of pollution in rural areas of China. The huge amount of data on livestock and poultry production cannot be ignored. If not handled properly, it will cause serious pollution to the environment. For example, if animal manure is not treated in a timely manner, it can cause serious pollution to surface water, groundwater, soil, and air.

The production equipment for cow manure organic fertilizer has a compact process layout, scientific rationality, advanced technology, energy conservation and consumption reduction, no three emissions, stable operation, reliable operation, convenient maintenance, and wide adaptability to raw materials. Adapting to various ratios of organic compound fertilizers, bio organic fertilizers, urban sludge, household waste organic fertilizers, etc., is a promotion project of practical environmental protection technology in the country.

The small-scale cow manure organic fertilizer production line has simple and complete configurations, which only require crushing, stirring, granulation, screening, and packaging processes. The entire set of equipment only costs tens of thousands of yuan, which is suitable for customers who do not have sufficient funds in the early stage. When there is sufficient funds in the later stage, they can add a flipper, dryer, cooler, and coating machine to form a complete organic fertilizer production line.

The price of organic fertilizer production lines varies depending on the equipment you need, ranging from tens of thousands to hundreds of thousands of yuan. This is mainly determined by the type of finished product and production volume you need. For example, if only one flipping machine is needed for aerobic fermentation treatment of livestock and poultry manure, it only requires tens of thousands of yuan to purchase a flipping machine. However, if you want to equip a complete set of equipment, the cost may start at tens of thousands of yuan.

Necessary processes for processing high-quality granular fertilizers on organic fertilizer production lines

With the rapid development of animal husbandry and planting, a large amount of livestock and poultry manure produced by large-scale farming has become a source of pollution if it is not disposed of in time. How to control these pollution sources from the source and utilize them rationally as soon as possible? Combining various factors, the ideal way is to use various organic fertilizer npk fertilizer production line and their processing equipment to recycle and ecologically utilize these wastes.

Composting is mainly divided into aerobic composting and anaerobic composting. At present, aerobic composting is mainly used. The composted manure has more stable nutrients, is more conducive to crop absorption, and can improve soil conditions. Therefore, farmers, small and medium-sized farms or farms mostly use this organic fertilizer equipment treatment mode.

The most common types of granulation are double roller granulator, disc granulator, tooth stirring granulator and drum granulator. The granules produced by each granulator are different, and the applicable materials have certain requirements. , the type of granulator can be determined according to the selection of raw materials.

In the organic fertilizer npk manufacturing process, the dryer dries the excess water in the organic fertilizer particles, which is convenient for material storage and not easy to deteriorate. In the production process of biological fertilizers, not only the water content of the granules after forming generally exceeds the index and needs to be dried at low temperature, but also the water content of the organic raw materials after fermentation is about 30% to 40%, and the water content of the granules after granulation is generally 15%between % and 20%, the fertilizer quality index requires that the moisture content is less than 14%, and it needs to be dried. The drying section is an indispensable and important process in the production process of biological fertilizers, which directly affects the output, quality and energy consumption. It is very important to choose the model and specification of the dryer reasonably and control the process conditions.

The noise reduction method of organic fertilizer granulator in the granulation process

fertilizer granulator May 23, 2024

The organic fertilizer granulator consists of several parts. First, it’s the collection part of the device. Secondly, it is the most important transmission component and also a bracket device with special technology. Finally, there are conveyor belts and auxiliary wheels, and different granulators have different granulation characteristics.

1. The principle of rotary drum granulator is that the material relies on the surface tension, an appropriate amount of liquid phase, and the extrusion force generated by the rolling between the materials.

2. The processing operation of the double roller granulator equipment adopts the non-drying and normal temperature process, the particle strength is high, and the bulk specific gravity increase is more obvious than other granulation methods, especially suitable for occasions where the product bulk specific gravity increases.

3. The new organic fertilizer granulator uses the high-speed rotating mechanical stirring force and the generated aerodynamic force to continuously realize the mixing, granulation, spheroidization, densification and other processes of fine powder materials in the machine, so as to achieve the purpose of granulation.

4. The control of water content, material quality and water temperature in the operation of the disc granulator of organic fertilizer equipment.

How to reduce the noise of the organic fertilizer granulator in the npk manufacturing process, there are the following suggestions:

1. There may be a problem with the bearing of a certain part of the organic fertilizer granulator, which makes the machine work abnormally, the working current fluctuates, and the working current is too high.

2. The ring die is blocked, or a part of the die hole is detached from the material. If the ring die enters the foreign body, the ring die is out of the circle, the gap between the roller and the die is too tight, the roller is worn or the roller bearing is damaged and cannot rotate, which will cause the vibration of the granulator.

3. The coupling correction is unbalanced, the height and height are deviated, the granulator vibrates, and the gear shaft oil seal is easily damaged.

4. If the main shaft is not tightened, the loosening of the main shaft will cause axial movement before and after the movement, the roller swings obviously, the granulator is noisy, and the granulation is difficult.

5. The wear of the big gear and the pinion, or the replacement of a single gear, will also produce a lot of noise.

fertilizer granulator May 23, 2024

The organic fertilizer pellet production line project is a process that uses organic waste fermented by microorganisms to produce organic fertilizer through granulation.

Process flow of a daily production line for 500 tons of straw granular organic fertilizer

1. Mainly, raw materials containing organic matter (such as sheep manure, pig manure, sludge, chicken manure, duck manure, cow manure) with a moisture content of about 70% are mixed with crushed organic waste (such as straw, corn straw and branches, mushroom residue) and then added with a biological fermentation agent for fermentation.

2. Use a forklift to load the mixed (sheep manure, pig manure, sludge, chicken manure, duck manure, cow manure) and other plant straw into a fermentation and maturation tank, and evenly add fermentation bacteria for maturation.

3. Fermented raw materials can be directly transported to the organic fertilizer crusher for crushing through an automatic material system using a belt conveyor. The crushed materials can be directly transported to the screening machine using a belt conveyor. The screening machine screens out impurities that are not fully decomposed or crushed, and then uses a belt conveyor to transport them to the waste disposal site for processing;

4. After fermentation and crushing, the raw materials are accurately proportioned (bentonite, humic acid) with a forklift into the automatic batching bin and other raw materials (adding nitrogen, phosphorus, and potassium with a total nutrient content of less than 25%) to produce organic and inorganic fertilizer compound fertilizers. After proportioning, they are quickly and evenly stirred by a mixer.

5. It enters the organic fertilizer granulator through a belt conveyor, and a small amount of water is added to the inlet for granulation. The particles formed by the granulator are then transported by the belt conveyor to the rounding machine for shaping

6. After drying and cooling, the particles are sieved by a belt conveyor through a powder screening machine for final product screening. The particles that do not meet the requirements are transported to the waste crusher by a (finished particle 2-4mm) belt conveyor for thorough crushing, and then returned to the granulator for further granulation by the return material belt conveyor.

7. After sieving the powder, the particles are coated by a coating machine and can be added (functional bacteria can produce bio organic fertilizers)

8. After adding functional bacteria to the coating machine, the particles are transported by a belt conveyor to the second screening machine for particle size screening. The particles (2mm and 4mm) can be separated and packaged separately, making them more beautiful,

Debugging method and granulation process of organic fertilizer double roll extrusion granulator

fertilizer granulator May 23, 2024

Advantages of double roller granulator:

1. Low energy consumption and energy saving road roller extrusion granulation is a kind of material granulation at room temperature. Compared with other methods, it does not require drying measures such as fuel and gas.

2. The low investment is due to the saving of the drying process, the low rate of return (about 15% of the total feed of the extruder), the simple process flow and the low investment.

3. The consumption capacity of extrusion granulation is only electricity, and there is no three waste discharge for environmental protection.

The double roller granulator has the characteristics of low energy consumption, high energy saving, low investment, simple operation, and no pollution of equipment emissions. Before the production of the npk fertilizer production line, the installation of the roller extrusion granulator needs to be debugged. Take the right approach:

1. Adjustment of the roller gap: In the npk manufacturing process, sometimes it is necessary to increase the output or bite angle, at this time, the distance between the two compression shafts can be increased, and the distance between the active shaft and the passive shaft can be increased. The steps are as follows: stop the machine, remove the upper rack of the two bearing seats, adjust the adjustment plate between the two bearing seats to the required thickness, the rollers cannot collide between the two rollers, and the minimum should be kept between 0.3-1mm.

2. The alignment adjustment of the ball socket. The ball socket is formed by the dimples on the main roller surface, so there are problems of axial alignment and circumferential alignment:

1) The axial alignment has been adjusted during installation. Generally speaking, it is not possible to adjust. When adjustment is required, tighten or loosen the glands on both sides of the passive bearing seat, thereby pushing the displacement of the eccentric sleeve to be in line with the drive shaft roller. correspond.

2) Align the ring direction, loosen the six connecting bolts between the driven gear and the adjusting sleeve, so that the adjusting device and the driven gear are slightly separated. Since the ball seat adjustment is considered in the design and two adjustment bolts are installed, the dislocation can be adjusted regardless of the dislocation.
