The investment cost of NPK fertilizer production line varies greatly depending on multiple factors, including the scale of the production line, degree of automation, equipment selection, raw material processing requirements, geographical location, construction costs, and whether additional facilities (such as warehouses, laboratories, etc.) are needed. The following are some of the main factors that affect the investment cost of NPK fertilizer production lines and their possible ranges, but please note that these are for reference only and the actual cost may vary depending on the specific project:

NPK fertilizer production line scale: The investment for small-scale production lines (with an annual production capacity of less than 10000 tons) may range from tens of thousands to several million RMB; The investment for medium-sized production lines (with an annual capacity of 10000 to 50000 tons) may range from several million to tens of millions of RMB; The investment in large-scale production lines (with an annual production capacity of over 50000 tons) may exceed tens of millions or even hundreds of millions of RMB.

Equipment selection: High end and highly automated equipment have higher prices, but lower long-term operating and maintenance costs. For example, a fully automated granulator may cost several times more than a traditional manually controlled granulator.

Raw material processing: If raw materials require pre-treatment (such as drying, crushing), additional equipment and costs may be required. The cost of pre-processing equipment may range from tens of thousands to hundreds of thousands of RMB.

Geographical location: The cost of building production lines varies greatly in different countries or regions, including land costs, construction costs, labor costs, transportation costs, etc. For example, the cost of building production lines in developed countries may be much higher than in developing countries.

Auxiliary facilities: including raw material warehouse, finished product warehouse, laboratory, office area, etc. The construction and operation costs of these facilities also need to be included in the total investment.

Installation and commissioning: The installation and commissioning of new equipment also require a certain cost, which may account for 5% -10% of the total investment.

Reasonable material structure improves the granulation efficiency of rotary drum granulator

fertilizer granulator Aug 23, 2024

In order to improve the pelletizing rate of the rotary drum granulator, it is necessary to configure the material structure reasonably in order to improve the pelletizing rate of the rotary drum granulator.

Material structure mainly refers to the following aspects.

1. Reasonable matching of fineness of raw materials. According to our experience, the fineness of the whole raw material should be matched as follows: raw materials of 100-60 mesh account for about 30% – 40%, raw materials of 60 mesh to diameter of 1.00 mm account for about 35%, and small particles with a diameter of 1.00-2.00 mm account for about 25% – 30%. The higher the fineness of the material, the better the viscosity, and the higher the surface finish after granulation. However, in the production process, the use of super proportion of high fineness materials can easily lead to the problems of too large particles, irregular particles and material sticking to the wall.

2. Reasonable collocation of cohesive materials and dispersive materials. In the production process formula, the proportion of viscous raw materials is high, which is easy to form balls, the proportion of dispersive raw materials is high, and there are more fine powders. In the conventional formula of fertilizer production line, the proportion of viscous raw material for low concentration compound fertilizer is 45% – 50%, and that of high concentration compound fertilizer is 35% – 40%. At the same time, it should be combined with material fineness. If the matching is not good, there will be no fine powder, no particles, particles are not round, easy to get big ball and so on.

3. Chemical reactions between materials should be considered in formulation. After the formulation of some materials, free water will be precipitated during the production process, which will cause the liquid phase of the material to exceed the standard and cannot be produced normally. Some raw materials will greatly reduce the critical relative humidity of the mixture after matching. During the production process, due to the large amount of moisture absorption Unable to produce normally. Therefore, the chemical reaction between the materials must be considered when formulating to achieve a reasonable match between the materials.

4. The comprehensive moisture content of materials after mixing. The water content of raw materials directly affects the granulation. Even if steam and water are not added in the production of some materials after mixing, they can not be produced normally. Therefore, low moisture content of materials in organic fertilizer production line is conducive to the addition of steam in granulation. This is beneficial to improve the temperature and viscosity of the materials, thus improving the compatibility and pelletizing rate of the materials.

What factors affect the energy consumption of fertilizer crushers in NPK fertilizer production

fertilizer granulator Aug 23, 2024

In the production of NPK fertilizers, the energy consumption of fertilizer crushers is influenced by various factors, including the physical properties of the materials as well as the operation and design of the equipment. Understanding these influencing factors can help optimize the crushing process and reduce energy consumption. Here are some of the main influencing factors:

Material hardness and toughness: The higher the hardness and toughness of the material, the more energy is required for crushing. Materials with excessively high hardness can significantly increase the energy consumption of the crusher, so when choosing a crusher, it is necessary to consider the hardness characteristics of the material.

Material humidity: Materials with high humidity are prone to adhere to the interior of the equipment during the crushing process, forming bonds or clumps, which increases the difficulty and energy consumption of crushing. Pre drying materials can effectively reduce energy consumption.

Feed particle size: The larger the feed particle size, the more energy is required to grind it to the desired particle size. Pre screening or pre crushing can reduce the particle size of the feed and lower energy consumption.

Target granularity: Crushing to finer granularity requires more energy. Reasonably setting target granularity based on production needs to avoid excessive crushing can effectively save energy.

Types and designs of fertilizer crushers: Different types of crushers have different energy conversion efficiencies. For example, there is a significant difference in energy consumption between hammer crushers and cage crushers when processing materials with different characteristics. Optimizing equipment design, such as improving transmission efficiency, reducing friction losses, and also reducing energy consumption.

Operating parameters: including the speed of the fertilizer crushers, feed rate, equipment load, etc. Excessive speed or load can increase energy consumption, and reasonable operating parameter settings can optimize energy use.

Maintenance status: The wear and maintenance of equipment have a significant impact on energy consumption. Severely worn components will increase friction losses, leading to increased energy consumption. Regular maintenance and timely replacement of worn parts can maintain the optimal operating condition of the equipment and reduce energy consumption.

Environmental temperature: Higher environmental temperatures may affect the cooling efficiency of equipment and increase energy consumption. Keeping the equipment running at an appropriate temperature can reduce energy consumption.

By controlling and optimizing the above factors, it is possible to effectively reduce energy consumption in NPK fertilizer production while ensuring the crushing effect of the fertilizer crushers, achieving a dual improvement in economic and environmental benefits.

A large amount of chemical fertilizer has a great impact on the land. In fact, the efficiency of sheep manure is very high. If it is used as fertilizer after being decomposed and fermented by organic fertilizer production line, it is very good for soil and crops. Let’s take a look at the following, fermented sheep manure do fertilizer have what benefits.

Soil itself has a lot of trace elements, but can not be absorbed by plants. However, there are a lot of organic components in sheep manure, which can make the soil more fertile. Moreover, various elements in it can be decomposed and utilized better, so as to improve soil fertility.

Using decomposed and fermented sheep manure as fertilizer can make a large number of beneficial microorganisms in the soil, which can improve the soil. In addition, after these beneficial ingredients die, the soil can become more loose. If there are more beneficial microorganisms, the soil will enter into a good cycle, and all kinds of harmful ingredients will be inhibited. In this way, the amount of pesticide used can also be reduced. At the same time, there are many enzymes in sheep manure, which can make the land more active when used in the soil. Then it is made into granules by fertilizer granulator to prolong fertilizer efficiency and promote plant production.

The results showed that there were more nutrients and more trace elements in sheep manure after fermented with organic fertilizer. At the same time, the fermented sheep dung can absorb heavy metals, which can reduce the pollution of crops and make the roots grow better.

Moreover, fermented sheep manure can improve the stress resistance of crops. There are a lot of ingredients in sheep dung, which are natural antibiotics, so that the resistance of crops is better, and it is not easy to infect diseases. It can also make the crops more drought resistant, waterlogging resistant and more adaptable.

It’s safer to use. After the organic fertilizer production line, the sheep dung will not burn roots and seedlings due to secondary fermentation, so it can be used safely. Our NPK fertilizer granulator is suitable for granulation of various fertilizers.

How to adjust the speed of fertilizer granulator to improve granulation efficiency

fertilizer granulator Aug 23, 2024

The speed regulation of fertilizer granulator is one of the key factors to improve granulation efficiency and particle quality. The correct speed setting can optimize the granulation process, but too low or too high a speed can affect the granulation effect. Here is a guide on how to improve granulation efficiency by adjusting the speed of the granulator:

Understand the relationship between rotational speed and granulation efficiency:

When the speed is low, the mixing and rolling effect of materials inside the fertilizer granulator is poor, which may lead to slow particle formation and low granulation efficiency.

When the rotation speed is high, although it can accelerate the rolling and mixing of materials, excessive rotation speed may lead to increased wear between particles, affecting the integrity and strength of particles, and increasing the energy consumption and wear of equipment.

Determine the optimal speed range:

Determine the optimal speed range suitable for specific material characteristics and production needs through experiments or reference to equipment manufacturers’ recommendations. This usually requires consideration of factors such as material particle size, humidity, and adhesion.

Some granulators, such as drum granulators, may have an optimal speed between 60% and 70% of the critical speed, which helps the material form the best parabolic motion inside the granulator and promotes particle formation.

Gradual adjustment:

During the production process, the speed of the granulator can be gradually adjusted to observe changes in particle quality and production efficiency. By fine-tuning the speed, find the speed point that can improve granulation efficiency without affecting particle quality.

When adjusting, it is recommended to only increase or decrease the speed by a certain proportion each time to avoid significant changes that may have adverse effects on the granulation process.

Monitoring and feedback:

Real time monitoring of the operating status of the fertilizer granulator using sensors and monitoring systems, including parameters such as speed, temperature, pressure, as well as quality indicators such as particle shape, size, and density.

Adjust the speed in a timely manner based on monitoring data and production requirements to maintain the stability and efficiency of the granulation process.

Consider changes in material characteristics:

The characteristics of materials, such as humidity and particle size, may change during the production process. Therefore, the adjustment of speed should take into account these changes to adapt to different batches or types of raw materials.

Regular calibration and maintenance:

Regularly inspect and calibrate the speed control device of the granulator to ensure its accuracy and reliability.

Regularly maintain the granulator, inspect and replace worn parts to avoid unstable speed caused by equipment failure.

Through the above methods, the speed of the granulator can be effectively adjusted to improve granulation efficiency and particle quality, while reducing energy consumption and equipment wear, achieving optimization of the production process. During the adjustment process, it is recommended to collaborate with equipment suppliers or industry experts to obtain more professional guidance and advice.
