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.

fertilizer granulator Apr 25, 2024

For the production of compound fertilizers, a double roller granulator is essential. What equipment is needed in addition to the double roller granulator to produce compound fertilizers?

Compound fertilizer granulation press granulator, what supporting equipment is needed for compound fertilizer granulator? Roll extrusion granulator is the main equipment for compound fertilizer granulation of powder materials. In addition to the roller extrusion granulator, the entire npk fertilizer production line also needs automatic batching machines, mixers, vertical pulverizers, drum screening machines, dryers, coolers, secondary drum screening machines, and automatic packaging scales. Belt conveyor connection.

The principle of the double-roll extrusion granulator: The double roller granulator adopts two rollers, leaving a certain gap (adjustable) between each other, and the two reverse at the same speed. There are many arc grooves of the same shape and size on the surface of the roll. According to the difference of the target compression ratio of the material, the trough of the arc groove of one roll is selected to be aligned with the trough of the other roll. The two rollers are horizontally parallel, and the powdery material is continuously fed from the top of the two rollers, evenly relying on self-weight and forced feeding between the two rollers. When the material enters the bite, it is gradually bitten by the roller. With the continuous rotation of the roll, the space occupied by the material is gradually reduced and compressed.

How to solve the problem of high moisture content in fertilizer particles after granulation

fertilizer granulator Apr 25, 2024

Whether it is in the organic fertilizer production line or npk fertilizer production line, after the organic fertilizer granulator (roller granulator, disc granulator, drum granulator, etc.), the fertilizer granules will have moisture. How to find a way to deal with the granules What should I do if the moisture of fertilizer granules is too high after granulation? Then we will use coolers in the production of organic fertilizer production equipment. The cooler is the main equipment of the production system on the fertilizer processing line, with a simple structure and good stability.

The cooling equipment is specially designed for the needs of producing granular organic fertilizers and can be used in npk production line and organic fertilizer production lines. In the production of granular organic fertilizer, the granular organic fertilizer produced by the granular press needs to go through a cooling process to achieve the purpose of cooling and dehydration. In the existing equipment configuration, there are mainly two kinds of granular organic fertilizer cooling equipment, one is vertical cooler and the other is reverse flow cooler. The principle is that the temperature of the pellets produced by the pellet press is relatively high, generally 70~80°C. Through the cooling process of the cooler, the material can remove about 3 percent of water, which can meet the requirements of cooling and drying under ideal conditions.

The cooler is the main equipment of the production system on the fertilizer processing production line, with simple structure, good stability and reliable rotation. The waste gas after heat exchange can be introduced into the rotary kiln to improve the thermal efficiency of the whole system. Also known as drum cooler, it is used for the production of organic fertilizer and npk manufacturing process, cooling the fertilizer of a certain temperature and particle size, used together with the dryer. It can greatly improve the cooling speed, relieve labor intensity and improve efficiency. Further remove part of the water and reduce the grain temperature of the compound fertilizer. It can also be used for other powder. Granular material cooling. The cooling equipment has compact structure, high cooling efficiency, reliable performance and strong adaptability.

The application of semi wet material crusher in organic fertilizer production line

fertilizer granulator Apr 25, 2024

Semi wet material crusher is a professional crushing equipment for high humidity, multi fiber materials. The semi wet material crusher utilizes high-speed rotating blades to crush fibers with good particle size, high efficiency, and high energy. Semi wet material crushers are commonly used in the production and processing of organic fertilizers, and have good effects on crushing raw materials such as chicken manure and humic acid sodium.

A semi wet material crusher can also crush high humidity materials. It is composed of two sets of hammers on top and bottom, so it can also be called a double wet material crusher. Its basic structure is improved on the basis of the old hammer crusher, and it can be considered a relatively new type of double crusher structure.

The semi wet material crusher effectively solves the problem of high moisture content in materials. Even if the moisture content is high, the sample is easy to break and will not cause machine blockage. This is because the double crusher is designed without a screen bottom and mesh, so even if the moisture point of the material is large, blockage will not occur. Even on rainy days, normal production can still be carried out. In addition, although the coal crusher does not have a bottom screen, it uses two rotors on top and bottom for crushing, resulting in a more uniform and ultrafine discharge particle size, which can be controlled below 2 millimeters.

fertilizer granulator Apr 25, 2024

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.

How to control moisture during granulation of organic fertilizer granulator

fertilizer granulator Apr 25, 2024

Common organic fertilizer granulators include: npk fertilizer granulator, rotary drum granulator, disc granulator, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator, ring Various granulators have their own production characteristics, and the prices of granulators vary.

In the organic fertilizer granulation or npk manufacturing process, the raw materials are required to have a certain viscosity. Some raw materials are relatively loose after fermentation and are not easy to granulate. A certain amount of water or binder must be added to increase the viscosity of the material. Organic fertilizer machinery and equipment, such as disc granulator and drum granulator, etc., add water or binder during the whole granulation process to ensure the successful granulation of materials. The new organic fertilizer granulator adopts dry granulation, and the mellow material can be granulated immediately without other processing techniques. The double roller granulator is also manufactured by normal temperature processing technology, which is suitable for materials with low viscosity or low water content.

If the moisture content of the material is too high, some dry materials can be added appropriately to neutralize the moisture. If the water content is too low, you can take an appropriate amount of water to facilitate granulation.

The new organic fertilizer granulator is a kind of organic fertilizer granulator, which is constantly updated and transformed with the development trend of modern agriculture, technological progress and diversity of requirements. The new organic fertilizer wet test granulator can be used completely, and various reasonable and mellow organic matter can be granulated according to the new organic fertilizer granulator, which gets rid of the limitations and obstacles of traditional technology. There is no need to stop the daily tasks of raw material handling, crushing, and punching before granulation, and can be granulated immediately, which not only saves a small amount of power engineering project investment, reduces cost effectiveness, but also improves the efficiency of daily tasks, saving time and energy , the actual effect is satisfactory.
