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.

Model Selection of Organic Fertilizer Granulator

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

The difference in the selection of organic fertilizer granulator models lies in the selection of appropriate granulation methods according to the use requirements of materials. This is just a big general term. There are subdivisions and branches under it. It is mainly divided into dry method and wet method:

Dry process mainly refers to products with relatively low water content. Generally, water content below 10% is a zero limit. (There are also few materials that can reach 16%, for example, some materials only carry crystal water.) Most of the particles produced by dry granulation are irregular particles (for example, ordinary granular potassium fertilizer) or the more common shape is similar to small gravel. With the current industrial upgrading and increasingly strict environmental protection requirements in China, many chemicals and building materials need granulation.

The main index of wet granulation is the material with a water content of more than 20%. There are various equipment and methods for wet granulation. For example, disc granulation, drum granulation and spiral granulation have been carried forward many years ago, and have been greatly improved by increasing the use environment and processing requirements of different materials. For example, the particle size of relatively popular organic fertilizers over the years ranges from 1mm to 6mm. These methods were adopted.

Compared with wet granulation, dry granulation in organic fertilizer granulator consumes less energy, is more environmentally friendly, does not require drying, does not add water and binder, and does not change the properties of materials; Compared with wet granulation, these are also several advantages of dry granulation. It is more suitable for industrial production.

In another case, some materials require relatively small particle sizes. Products between dozens of meshes and 100 meshes can also be reduced by airflow, spray and rapid drying.

Equipment and technology of packaging machine in npk fertilizer production line

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

Automatic packaging machine is an indispensable production equipment of NPK production line, which improves the efficiency of the whole production process.

Innovation is an important part of the development of automatic fertilizer packaging machine. Although there are many kinds of automatic fertilizer packaging machines, most of them are semi-automatic operation. They only carry out targeted bagging and sewing. The packaging method is relatively single and lack of innovative elements. If we don’t pay attention to the renewal of packaging machine technology, the enterprise will be eliminated in the saturated automatic packaging machine market in the future.

Fertilizer automatic packing machine

Automation and intelligence of mechanical equipment is always the direction of its development. Only by constantly innovating and adapting to the needs of the market, can the packaging industry walk out of a new production road. In addition, the technological innovation and upgrading of fertilizer packaging machinery will become a powerful boost to the development of enterprises, and the fertilizer automatic packaging machine, which starts to develop in the direction of diversification, will change the traditional production mode and will develop rapidly. In the fertilizer production industry, the granules produced by the organic fertilizer granulator machine are quantitatively packed in the flow industry.

Through the continuous use of high technology, the position of the automatic packaging machine in the market is becoming more and more stable, and at the same time, its development is opened. Continuously through the improvement of technology, it not only guarantees the efficiency and quality of product packaging production, but also makes it easier to expand into new markets. , To open a new field of development for it. At present, it has been imitated by many companies, but it is still unable to surpass in terms of corporate image and after-sales service, forming a situation where the packaging machine market is uneven and mixed.

We also need to know that the success of the automatic quantitative packaging machine comes from the perfect application of science and technology, and the automatic packaging machine is fully used in the fertilizer production line. In order to maintain its market position, manufacturers of automatic fertilizer packaging machines must carry out the application of science and technology to the end and continuously improve the independent innovation capabilities of core technical personnel.

The reason of raw material precipitation during npk fertilizer granulation

Written by fertilizer production line on December 22nd, 2022.

When some compound fertilizer equipment production lines are processed by rotary drum granulator, they can dissolve the fertilizer into a certain proportion, but if the energy exceeds a certain amount, it will produce salt analysis and precipitate another substance.

Amino acids and zinc sulfate dissolve well in water, but when they are together, Zinc Sulfate Precipitates amino acids. The pH value of solution, part of the supply, metal salt dissolved in acid will produce precipitation and dissolve in alkaline medium, while some substances such as humic acid will form precipitation and dissolve in acid solution. Amino acids and humic acids can be analyzed by salt analysis, zinc, copper, iron, manganese and salt analysis. Therefore, it is more important to choose suitable raw materials for fertilizer production.

Fertilizer granulator granulation should consider whether the substances are compatible. Some substances cannot be mixed in the precipitation reaction, and precipitation occurs when they are mixed into water, such as zinc, copper, iron and manganese plasma. In the case of phosphate, borax will precipitate, the precipitate is insoluble in water, and the phosphate precipitates molybdate ammonia water, and these commodities cannot be produced at the same time. They not only produce precipitation, but also lose their fertilizer efficiency.

Raw materials are insoluble in water, so the proportion of fertilizer is blindly increased. At room temperature, the solubility of borax and boric acid in water is 30 kg / T, and most of them will precipitate. If several kinds of fertilizers are soluble in water, there is also a great demand. For example, zinc sulfate is soluble in water, potassium sulfate is soluble in water, and two kinds of raw materials are soluble in water, which can produce potassium sulfate crystals.
