Common organic fertilizer granulators include: double roller granulator, rotary drum granulator, disc granulator machine, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator, Ring die granulator, etc. Today we will talk about the skills of choosing an organic fertilizer granulator.

Selection skills of disc granulator machine: First of all, be familiar with the performance characteristics of the disc granulator.

Disc granulator is divided into two types: plane rotating disc granulator and inclined disc granulator. It is a professional organic fertilizer equipment for producing spherical granules.

The inclined disc granulator is a traditional process. The base of the disc granulator is fixed, the reducer runs through the motor, and then pushes the outer disc of the inclined disc granulator to rotate, and the incoming material rolls into a ball. The disc granulator has low rotation speed and adjustable inclination angle, and is suitable for producing spherical granules of organic fertilizer, compound fertilizer, chemical raw material, biological bacterial fertilizer and biological fertilizer. Both organic fertilizer production lines and npk production line can be used, which are characterized by high output and simple operation.

The characteristics of the plane rotary disc granulator are that the main body is fixed, the inner disc rotates, and the material entering the disc through centrifugal rotation is rolled into a ball. The plane rotating disc granulator runs at a higher speed and is more suitable for materials with good adhesion, high density and low output requirements. It is characterized by high particle symmetry and fast discharge.

With the upgrading of organic fertilizer equipment, the new horizontal centrifugal organic fertilizer granulator has become the leading role of the disc granulator, and the output and particle symmetry have been raised to a new level.

What equipment does the annual production line of 20000 tons of cow manure organic fertilizer belong to a medium to large scale?

1、 Fermentation equipment

The fermentation process plays a crucial role in the production of organic fertilizers, and can even determine the quality of organic fertilizers. There are two common fermentation equipment in an organic fertilizer production line with an annual output of 20000 tons:

Very suitable for medium to large organic fertilizer equipment factories.

2、 Cow manure manure fertilizer making equipment

Due to its suitability for agricultural production, granular organic fertilizers are quite popular in the market. A production line with an annual output of 20000 tons is relatively large, and it is recommended to equip it with granulation equipment.

The fertilizer making equipment mainly includes crushers, screening machines, granulators, dryers, cooling machines, packaging machines, etc. Except for the various types of granulation equipment, the other types of equipment are relatively single, with only differences in specifications and sizes.

The granulation equipment mainly includes rotary granulator, toothed granulator, disc granulator, flat mold granulator, etc. Suitable equipment can be configured according to the actual situation of the site, finished product form, etc.

The organic fertilizer vertical crusher is an optimized design based on advanced fine crushing equipment, which is a non sieve and adjustable fine crushing equipment, and can be widely used as the mainstream equipment in fertilizer equipment. It is also a crushing equipment used in the compound fertilizer industry, suitable for crushing raw materials and return materials, especially for materials with high moisture content, with strong adaptability, not easy to block, and smooth feeding.

The material enters from the feeding port and collides with the high-speed rotating casing inside the casing. After being impacted, the material is compressed and crushed, and then collides with the inner wall of the casing for counterattack before colliding with the hammer. During the falling process, it undergoes several impacts and becomes powder or particles below 3mm, which are discharged from the lower part

The organic fertilizer vertical crusher adopts a counterattack crushing mechanism, which saves about 20% energy and improves production efficiency by 20-25% compared to other similar equipment. If used in the grinding process, the effect is more significant in terms of system energy conservation and increased mill output.

The organic fertilizer production line is a series of equipment and processes that convert organic fertilizers into organic fertilizers. It is a very important part of the agricultural production process and can help farmers use fertilizers more efficiently to improve the growth rate and yield of crops. The complete fertilizer equipment includes the following main equipment.

Process steps for producing granular organic fertilizer from cow manure

Step 1: Fermentation and maturation

Collect cow manure and urine, mix them with straw, hay, and other materials to control the moisture content by about 65%. Stack the materials into long strips with a width of 2-5 meters or more, sprinkle 1KG of aerobic fermentation bacteria with 2-3 cubic meters, mix thoroughly with a wheeled composting machine, and let them ferment. After fermentation, use a composting machine to cool the materials.

Step 2: Material crushing

Crush the fermented and matured organic raw materials. Organic fertilizer wet material crusher is a professional crushing equipment for high humidity, multi fiber substances. By using high-speed rotating chains, the particle size of the crushed fibers is good.

Step 3: Mixing and stirring

Add trace elements, excipients, humic acid, clay, etc. and mix and stir. Using a vertical mixer, the mixing speed is fast and the uniformity is good. It can mix viscous materials with an added liquid of 30%. During operation, there are two opposite rotating blade rotors stirred in the middle. Adopting a lower door for fast unloading speed and minimal residue.

Step 4: Forming granulation

The material is granulated using a disc granulator, an organic fertilizer stirring tooth granulator, or a new type of stirring tooth rotating strand three combination granulator.

Step 5: Drum drying

The organic fertilizer dryer further removes moisture from the granulated particles to meet the standard requirements for organic fertilizer moisture content.

Step 6: Drum cooling

Cooling the dried particle material with a cooling machine helps to preserve the quality of the particle storage.

Step 7: Screening and return system

Due to the difference in particle size of the granular material output by the granulation and forming system, it needs to be screened and graded. The selected drum type screening machine requires low vibration, low noise, convenient screen replacement, and is equipped with a screen cleaning device.

Step 8: Particle coating equipment

The coating machine is composed of a screw conveyor, a mixing tank, an oil pump, a main engine, etc., and is used for powder flapping or liquid coating technology. It can effectively prevent fertilizer from clumping, and the host is lined with polypropylene or acid resistant stainless steel.

Step 9: Packaging equipment

Granular materials are packaged and transported through conveying equipment into the finished product warehouse. Granular materials are quantitatively weighed and packaged through automatic packaging scales.

NPK compound fertilizer is a multifunctional fertilizer that contains three main nutrients: nitrogen, phosphorus, and potassium, which can meet the nutritional needs of crops at different growth stages.

Equipment process flow of NPK compound fertilizer production line:

Usually includes raw material pretreatment, material batching, hopper lifting, mixing and homogenization, particle granulation, drying, screening and other processes. In this process, different devices are involved in each link.

Firstly, the pre-treatment stage of raw materials involves cleaning, crushing, screening, and other processes to ensure the purity and particle size uniformity of the raw materials. Then, in the material ingredient stage, various raw materials are mixed in a certain proportion to ensure a balanced nutritional composition of the final product.

Next, the prepared materials will be transported to the mixing and homogenization equipment through a hopper elevator, which can fully mix and evenly distribute the materials. After the mixing and homogenization is completed, the material will enter the granular fertilizer granulator and be compressed into granules through the granulation process.

Finally, the particles will enter the fertilizer dryer for dehumidification treatment, and then pass through screening equipment for classification to obtain products of different specifications.

The above is a brief introduction to the process flow of NPK compound fertilizer production line equipment. There are various types of equipment involved in this process, but they all have their own characteristics and can effectively complete tasks in each link.

The organic fertilizer production line equipment includes: fermentation turner, crusher, feeder, horizontal mixer, double roller granulator, dryer, cooler, screening machine, weighing and packaging machine. Let’s take a look at the trommel screening machine. The trommel screening machine is a new generation of professional equipment for self-cleaning materials after the electric vibrating screen and the general mesh vibrating screen manufactured by major enterprises. It is generally suitable for the screening of solid materials with a particle size of less than 300mm. It has the characteristics of high screening efficiency, low noise, small dust volume, long service life, small maintenance, and convenient maintenance. It can be used in organic fertilizer and npk production line, etc, and its screening capacity is 60 tons/hour~1000 tons/hour.

Features of rotary screener machine:

(1) The screening efficiency is high, because the equipment is equipped with a plate screening mechanism. During the screening process, no matter whether the material entering the separation screen is sticky, wet or impurity, the relative movement of the screening machine and the screen body cannot stop the screening. Thus, the screening efficiency of the equipment is improved.

(2) The entire screening mechanism with a good working environment is designed in a sealed dust jacket, which completely eliminates the phenomenon of dust flying during the screening process, thereby improving the working environment.

(3) When the low-noise equipment is running, the noise formed by the material and the rotating screen is completely isolated by the sealing dust jacket, so that the noise cannot be transmitted to the outside of the equipment, thereby reducing the noise of the equipment.

(4) The equipment screen with long service life is composed of several round flat steels with a size of 16 mm × 12 mm, and its cross-sectional area is much larger than that of other separation equipment screens, thereby improving the service life.

Organic fertilizer is a common fertilizer, and now it is also a fertilizer strongly supported by the country. The use of chemical fertilizers is no longer advocated because the excessive use of chemical fertilizers has led to increasingly serious soil compaction. Promoting organic fertilizer is to solve soil compaction, increase soil organic matter and fertility, and organic fertilizer equipment is specialized in producing organic fertilizers. Therefore, the market for organic fertilizer equipment is very hot. In addition, the production of organic fertilizer requires fermentation to form. Below is an understanding of the granulation process of organic fertilizer equipment production lines:

1、 Mixing of ingredients

The organic fertilizer equipment uses two mixers to operate alternately. The operating formula puts N, P, K, M, additives, trace elements, etc. into the mixer, and after mixing evenly, they are placed on the conveyor belt to achieve continuous production and reduce the labor workload of workers.

2、 Mixed crushing

In this process, a horizontal crusher is used, which can crush large particles in the raw materials and fully mix them.

3、 Organic fertilizer equipment granulator

The choice of granulation method is very important in the production of organic fertilizer. There are various methods in the industry, such as disc, drum, and extrusion, which have stable performance and long service life. They can produce both organic fertilizer and inorganic fertilizer as well as organic-inorganic compound fertilizer. In this process, a new type of organic fertilizer granulation machine is selected.

4、 Drying

After granulation, most particles will form, but they will still contain water and must be dried. A dryer can achieve the effect of drying materials.

5、 Cooling

After drying, the material is transported by belt to the cooling machine. The rotary cooling machine is also a rotating cylinder filled with lifting plates. Under the action of the plates, the granular material is lifted and exchanges heat with the cold air sucked into the cylinder, cooled to near room temperature, further improving the particle strength and reducing moisture.

6、 Screening

After cooling, there are powdery materials present. The fine powder and large particles are all screened out using a screening machine. The fine powder is directly returned to the mixer and mixed with the raw materials through a return belt conveyor before participating in the granulation process again. After the large particles are crushed, they are returned to the mixer through the same return belt conveyor as the fine powder, forming a complete production cycle, and the finished product enters the packaging process.

7、 Organic fertilizer equipment packaging machine

Qualified finished products are packaged using a manual weighing scale or an automatic packaging machine.

The organic fertilizer equipment production line generally consists of multiple links, including raw material processing, fermentation processing, drying processing, and packaging. Firstly, organic raw materials are processed and sent to fermentation equipment for biological fermentation. Through the action of microorganisms, organic matter is transformed into organic fertilizer. Then, the fermented organic fertilizer will be dried to achieve appropriate moisture content and particle size for storage and use. Finally, after packaging and quality inspection, organic fertilizers can be officially launched into the market.

Organic fertilizer production equipment is generally divided into granular fertilizer production lines and powder fertilizer production lines, and the price difference between the two is as follows:

Production line for equipment with an annual output of 50000 tons of granular organic fertilizer:

The complete set of granular organic fertilizer production line equipment roughly includes: raw material crushing equipment – fermentation equipment – screening equipment – granulation equipment – drying equipment – cooling equipment – screening equipment – coating equipment – packaging equipment – conveying equipment, etc. The annual production of 50000 tons of granular organic fertilizer production line equipment varies depending on the configuration and degree of automation, with prices ranging from approximately 800000 to 3 million yuan;

Production line for equipment with an annual output of 50000 tons of powdered organic fertilizer:

The equipment for powdered organic fertilizer is relatively simple, mainly including raw material crushing equipment, fermentation equipment, screening equipment, packaging equipment, conveyor equipment, etc. The annual production of 50000 tons of powdered organic fertilizer production line equipment varies depending on the configuration and degree of automation, and the price is approximately 300000 to 600000 yuan

However, due to factors such as brand, materials, equipment configuration, specifications, and market, the price difference will also be relatively large. Therefore, it is necessary to have a comprehensive understanding and comparison before choosing to purchase organic fertilizer production equipment.

Whether it is an npk production line or an organic fertilizer production line, the basic equipment includes: crusher, feeder, horizontal mixer, fertilizer granulator, dryer, cooler, screening machine, weighing and packaging machine. Common organic fertilizer granulators include: double roller granulator, stock granulator, disc granulator machine, new organic fertilizer granulator, etc. During the production process of the fertilizer production line, the fertilizer must be transported , then you need a conveyor. Common conveyors include: belt conveyors, bucket elevators, large inclination belt conveyors, screw conveyors, etc. Today, let’s take a look at the reasons for the failure of bucket elevators.

Since the bucket elevator is started and used through the operation of the switching power supply, it is difficult to avoid problems on the motor during use. When the bucket elevator motor is abnormal. Please don’t panic. In this case, close the program as soon as possible. Find professional technicians to investigate common faults and find out the main cause of the problem. The following is a detailed description of the reasons for the failure of the bucket elevator motor, hoping to help you.

1. If the power of the motor you use does not match the bucket elevator you configured, the working voltage is too low, the raw materials cannot be transported normally, and the machine is likely to suspend operation. At this time, the motors must be disassembled and replaced to find all the motors that are consistent with the operating power of the bucket elevator.

2. Check whether it is the cause of poor installation quality or the difference between the motor and the spindle of the machine tool. Check if the motor is overheating when clearing installation common problems, based on a specific search by engineering construction technicians. If power engineering is popular, consider whether it is caused by excessive use time, and need to analyze detailed problems in depth.

3. Check whether the pressure of the packing screw cap is too tight or the adjustment of the mechanical seal torsion spring is too tight, and adjust the reduction of the screw cap or the mechanical seal torsion spring again.
