How to select suitable dryer in npk fertilizer production line

Written by fertilizer production line on January 7th, 2023.

In the production process of bio organic fertilizer, the moisture content of fertilizer is required to be lower than 14%. If the particles are too wet, they need to be dried. Therefore, drying is an indispensable and important process in the fertilizer production line, which directly affects the output, quality and energy consumption. It is very important to select the fertilizer granule dryer machine reasonably.

In the fertilizer production process, the fertilizer processed by the rotary drum granulator enters the dryer for drying. In order to avoid the death of effective live bacteria due to high temperature in the drying process, the temperature of hot air contacting with materials is different according to the moisture content of materials. It is suggested that the hot air temperature can be controlled in sections, which can improve the thermal efficiency and avoid the death of effective living bacteria.

Combined with these characteristics, a drum dryer suitable for low temperature and low moisture drying is selected, which can control the temperature of hot air to ensure that the material temperature is not higher than the specified temperature in the whole drying process. A cooler can be added at the tail of the machine, which can be cooled immediately after drying, which has the function of multi-purpose.

A section of secondary granulation area is set in the front of the rotary drum dryer for fertilizer, in which the material can realize secondary granulation. After that, the material is lifted up by the lifting plate for full drying. The wet hot air is drawn out through the exhaust fan through the pipeline at the tail of the dryer, and then enters the settling chamber for settlement. After the secondary dust reduction treatment, the tail gas of NPK production line can be discharged into the atmosphere.

double roller granulator is applicable to various NPK fertilizer production lines

Written by fertilizer production line on January 7th, 2023.

The rotary drum granulator can form powder materials through wet granulation process, which is suitable for the production of various NPK fertilizers.

Through the use of steam, the drum granulator improves the temperature and viscosity of the material, so that the moisture content of the material can be reduced in the pelletizing process, thus reducing the drying load, and the liquid phase distribution of steam is more uniform than that of adding water. Only when the liquid phase of the material is insufficient and the material is unstable, water can be added as a supplementary means.

The design of compound fertilizer production by rotary drum granulator is that steam pipe is buried in the material bed, and sprinkling water pipe is arranged above the material bed. Under the condition of stable production and supply, saturated steam can provide heat and part of water to humidify materials.

In the process of NPK production line treatment, we have encountered that due to unreasonable installation of steam nozzle and uneven distribution of material liquid phase, the place where there is more liquid phase of material will stick into big ball, and where there is insufficient liquid phase, the material is difficult to form ball, which affects the formation of particles. In view of this situation, we can increase the steam nozzle to increase the steam receiving area of the material.

How to use organic fertilizer composter to ferment fertilizer raw materials

Written by fertilizer production line on December 29th, 2022.

In the production of organic fertilizer, fermentation of organic raw materials is the first step. The decomposed materials determine the quality of organic matter, so composting is also a very important link in the fertilizer production line. How to ensure the smooth fermentation?

1. When the fermentation tank is used for composting, ventilation and oxygen supply should be ensured at the bottom of the fermentation tank.

2. The results showed that the suitable height and width of the compost were 0.8-1.5 m and 1.5-2.0 m respectively. The length of the compost could be determined by the material yield. The small volume of the compost was not conducive to temperature rise fermentation and complete decomposition.

3. If the composting time is too long or the straw is too much, fresh manure should be added to adjust the fermentation.

4. Cover the compost pile to avoid the compost on the air dried surface can not be completely fermented.

5. Naturally fermented compost needs to be adjusted accordingly before it can undergo secondary fermentation. The compost turning machine used in the fermentation process can improve the fermentation efficiency.

Troubleshooting of bucket elevator in NPK compound fertilizer production line

Written by fertilizer production line on December 29th, 2022.

Bucket elevator is used as the conveying equipment of organic fertilizer production line and npk blended fertilizer. How to deal with failures in the application process?

1. Aiming at the chain hook fracture problem of bucket elevator, the staff should lengthen the distance of the chain hook wire during maintenance, and add a reinforced base plate at the fixed part of the chain hook when installing the hopper, and weld the two parts together, so as to form a relatively complete chain link. This can not only reduce the occurrence of the chain hook fracture to a great extent, but also improve the safety One step to ensure the strength of the chain hook.

2. In view of the situation of the upper sprocket slipping, before NPK production line work, the relevant staff must check the situation of the sprocket of the elevator, and try to use the anti-skid sprocket as far as possible. The upper sprocket can be processed to form a chain nest shape, which can greatly reduce the occurrence of the sprocket slipping, and the transmission efficiency of the bucket elevator can also be effectively improved .

3. The bucket elevator transports the granules formed by the fertilizer granulator. In view of the situation that the materials stick to the wall in the bucket elevator shell, the shell situation must be fully considered when selecting the conveyor.

How to select appropriate equipment manufacturers for NPK fertilizer production line

Written by fertilizer production line on December 29th, 2022.

With the development of chemical fertilizer industry, NPK fertilizer equipment industry has developed rapidly in recent years, which has driven the development of the industry to a certain extent. NPK production line has been developing steadily. At present, the technological level of the world is to promote the development of numerical control technology by production as the mainstream, and the future development will be the same.

On the basis of further improving precision, efficiency, automation, intelligence and networking, our factory has gradually transformed fertilizer equipment into processing unit and cutting-edge flexible manufacturing system. At present, the fertilizer production equipment industry has entered the stage of scientific development and technology first, China’s international influence continues to heat up, and the industrial technology level is further improved. As our products are closely linked with strategic new industries, with the advantages of high efficiency, energy saving and high cost performance, our exports to developed countries are mainly at the middle and low end, and this part of consumer demand is rigid. Therefore, there is still a large market space for the development of fertilizer equipment industry.

Facing the huge demand of agricultural development, fertilizer granulator equipment manufacturers have the responsibility to continuously develop products with better quality, lower price and more suitable for recycling. If we want to process fertilizer into high quality commercial fertilizer, we must carry out granulation.

Our granulation equipment includes disc granulator, rotary drum granulator and roller extrusion granulator. Because different organic fertilizer components are different, the organic fertilizer particles produced are different, and different soil requires different fertilizer particle size. Granulator solves this problem, and can produce organic fertilizer with different particle size and shape according to different needs.
