Fertilizer granulator is a key agricultural machinery equipment that converts bulk fertilizer raw materials into granular fertilizers through a series of process steps for easy application and storage. In modern agricultural production, fertilizer granulators play an indispensable role, greatly improving the efficiency and quality of agricultural production.

Firstly, the fertilizer granulator achieves precise application of fertilizers. By compressing loose fertilizer raw materials into granules, uniform mixing and distribution of fertilizers can be achieved, ensuring that each piece of land can obtain sufficient nutrients. This precise application not only improves crop yield and quality, but also reduces fertilizer waste and lowers the cost of agricultural production.

Secondly, the fertilizer granulator improves the storage stability of fertilizers. Granular fertilizers are easier to store and transport than bulk fertilizers, and are less susceptible to moisture and oxygen, thereby extending the shelf life of fertilizers. This is crucial for agricultural production, especially in the case of seasonal fertilization and large-scale planting. Stable fertilizer storage can ensure that crops can obtain sufficient nutrients throughout the entire growing season.

In addition, fertilizer granulators can also improve the chemical properties of fertilizers. By adding specific additives during the manufacturing process, the hardness, dissolution rate, and nutrient release rate of fertilizer particles can be adjusted to better meet the needs of different types and growth stages of crops. This customized fertilizer can maximize the nutritional needs of crops and improve the ecological and economic benefits of agricultural production.

In summary, as a key tool in agricultural production, fertilizer granulators play an important role in improving agricultural production efficiency, improving soil quality, and protecting the ecological environment. With the continuous progress of technology and the increasing demand for agricultural production, fertilizer granulators will undoubtedly play a more important role in the future, providing strong support for the modernization process of agriculture. The key process for achieving fertilizer customization in NPK fertilizer production line

The NPK fertilizer production line is a set of process equipment specifically used for producing NPK compound fertilizers. Its main function is to mix various nutrients such as nitrogen (N), phosphorus (P), and potassium (K) in a certain ratio, and make granular compound fertilizers through specific processes. This production line is of great significance in modern agricultural production, as it can achieve customized production of fertilizers and meet the needs of different crops at different growth stages

The npk production line equipment usually includes: crusher, feeder, horizontal mixer, double roller granulator, dryer, cooler, screening machine, weighing and packaging machine. Especially in the production of npk compound fertilizers and organic fertilizers, pulverizers are essential production equipment.

1. The maintenance of pulverizer equipment needs to focus on the following aspects

1) Check whether the power supply, power socket, plug, and power cord are deoxygenated and broken.

2) Check whether the bearing is well lubricated, and use lubricating oil regularly for maintenance.

3) Check whether all fasteners are fastened, and deal with them in time if they are loose.

4) Check whether the transmission belt is installed correctly and in good condition. If the belt is damaged, it should be replaced in time. When there is oil on the belt or sheave, wipe it with a clean rag in time.

5) Check whether there are materials or other sundries in the damaged cavity, and remove them if necessary.

6) Check the sealing condition of the fan to prevent the sand from severely abrading the fan, causing the rivet heads of the impeller and hub to fall off, and fatigue cracks in the rivet holes.

Second, the following points should be paid attention to when inspecting and maintaining equipment

1) Bearing lubrication replacement: After the crusher works for 300 hours, the bearing should be cleaned. If the bearing is lubricated by engine oil, add new engine oil to fill 1/3 of the bearing seat gap, not more than half. Before operation, just tighten a small amount of regular oil cup cover. When the crusher bearing is seriously worn or damaged, it should be replaced in time, and attention should be paid to strengthening lubrication; adjust the paper pad at the bearing cover.

2) Replacement of claws and hammers: Among the crushing parts, the crushing claws and hammers are the vulnerable parts of the straw crusher, and they are also the main components that affect the crushing quality and productivity. The broken claws and hammers should be replaced in time after they are worn out. When replacing the claws of the claw crusher, the disc should be pulled out first. Before pulling it out, we need to remove the screws on it, and then pull it out.

Whether it is to build an organic fertilizer plant or an NPK compound fertilizer plant, it needs to spend a certain amount of money. The most important costs mainly include the following parts.

• Website construction costs. First, if you want to produce commercial NPK fertilizers, you need to buy or rent a production site. But this price needs to be calculated according to your local charging standard.

• Organic fertilizer equipment cost. The exact price of our machine is related to the machine capacity. But when you buy any machine, you need to consider the purchase cost and operating cost. Your procurement cost will be lower if you choose a machine manufacturer instead of an intermediate supplier. More importantly, if you choose a professional fertilizer equipment manufacturer, the machines you buy will be of good quality and low energy consumption, which will also greatly reduce your operating costs.

In the npk manufacturing process, if you want to use a dry granulator, you need to control the moisture content of the raw materials at about 10%. A clear advantage of using a dry granulator is that you don’t need to buy a dryer and cooler. Here, we recommend you to use the double roller granulator. It is a multifunctional granulator used to make fertilizers of various shapes.

However, for some NPK fertilizer producers, they want to buy wet granulator. Because the use of wet granulator will not produce dust. In addition, the price of wet granulator is lower than that of twin-roller granulator. And, you can choose the right one between pan granulator and rotary drum granulator.

•Labor costs. When you are going to run npk production line, you need some workers to help you. So, you need to spend some money to hire people. Generally speaking, the small NPK fertilizer plants we designed only need 3-4 workers. One person can feed the raw material, two workers can operate the machine, and the last one can be responsible for packing NPK fertilizer.

Huaqiang plant chemical fertilizer equipment rotary drum granulator solves the problem of wall sticking. Fertilizer drum steam granulation production process has greater output flexibility. The drum granulator is cylindrical and has good heat preservation effect. Using steam to increase the temperature of the material during granulation to meet the liquid phase required for granulation can greatly reduce the water content of the material during granulation, reduce the load of the dryer, and increase the output of the whole machine.

The granulation method of the rotary drum granulator, the double roller granulator adopts dry granulation, and the main working method of the drum granulator is wet granulation. After the base fertilizer is humidified by a certain amount of water or steam or gaseous ammonia or phosphoric acid or nitrogen solution in the cylinder, the compound fertilizer granulation process for chemical reaction and heat supply or the cold granulation process for a small amount of compound fertilizer adds water. Under the condition of temperature and humidity, with the help of the rotating motion of the cylinder, the material particles are squeezed and agglomerated into balls.

The improvement of the drum granulator, the drum granulator has a wide range of adaptability to raw material production. It can be used in conjunction with low-solubility and high-solubility materials as required, and can also be used in conjunction with some organic matter and medium and trace elements. In the process of organic fertilizer manufacturing, the wall sticking problem of the drum granulator is relatively serious, which directly affects the movement of materials, affects the ball forming rate and the roundness of particles. In order to solve this problem, we have developed a high lining for the inner wall of the granulator. The active lining of molecular materials solves the problem of material sticking to the wall and plays the role of anti-corrosion and heat preservation.

The drum granulator is suitable for nitrogen, phosphorus and potassium nutrients, and the ratio of nutrient distribution is flexible. It can process high-nitrogen compound fertilizers, various special fertilizers, organic and inorganic compound fertilizers containing more than 20% nitrogen, and can be used in both npk production line and organic fertilizer production lines.
