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.

In modern agriculture, organic agriculture is increasingly valued by people, and chicken farms, as an important agricultural production base, are actively exploring the path of resource recycling in the process of achieving sustainable development. This article will introduce how chicken farms use organic fertilizer production lines to process chicken manure into organic fertilizer, achieving maximum resource utilization.

1. Collection and treatment of chicken manure

The chicken manure produced by the chicken farm mainly comes from the cleaning of the chicken coop and by-products from the slaughter process. In order to ensure the quality and hygiene safety of chicken manure, chicken farms usually adopt strict management measures, such as regular cleaning of chicken coops and scientific treatment of poultry and livestock manure. The cleaned chicken manure will undergo preliminary treatment, including removing impurities, filtering, etc., to ensure the smooth progress of subsequent processing.

2. Processing of chicken manure

The preliminarily processed chicken manure will be sent to the processing workshop for processing. The processing process includes stages such as crushing, compression, and fermentation. Firstly, chicken manure will be sent to an organic fertilizer crusher for further processing. Then, the finely ground chicken manure will be sent to a compressor for compression, making it block or granular. Finally, the compressed chicken powder will be sent to the fermentation chamber for fermentation treatment, promoting the decomposition and transformation of organic substances.

3. Production of organic fertilizers

The fermented chicken manure will become the raw material for organic fertilizers. In the fermentation chamber, under suitable temperature and humidity conditions, the organic matter in chicken manure will be decomposed by microorganisms, producing organic fertilizers with high organic matter content and rich nutrients. After a certain period of fermentation, chicken manure will gradually turn dark brown and emit a pungent odor, indicating that the fermentation process has been completed.

4. Application of organic fertilizers

The organic fertilizers produced can be widely used in agricultural production. Chicken farms can use organic fertilizers to fertilize crops, in order to improve soil fertility and maintain soil ecological balance. Meanwhile, organic fertilizers can also serve as one of the important conditions for organic certification in ecological aquaculture, providing better market competitiveness for chicken farms.

By processing chicken manure into organic fertilizer through organic fertilizer production lines, the chicken farm has achieved resource recycling, not only reducing waste emissions, but also providing an important source of organic fertilizer for agricultural production. The production and application of organic fertilizers are not only beneficial for soil improvement and crop growth, but also contribute to promoting sustainable development of the agricultural industry and achieving coordinated development of economy, society, and environment.
