Processing sulfur coated urea in 15 t / h NPK fertilizer production line
Sulfur coated urea is a kind of coated slow release nitrogen fertilizer. In the process of NPK fertilizer production line, spherical urea is coated with a layer of molten sulfur to improve the physical properties of urea.

Sulfur coated urea is increasing in agricultural applications. With the increase of high concentration fertilizer application rate, the application amount of sulfur-containing super phosphate was relatively reduced, and the crop yield increased. The amount of desulfurization in soil increases, and the area of sulfur deficient land is expanding at home and abroad.

Therefore, the application of sulfur coated urea can not only improve the utilization rate of nitrogen, but also supplement the sulfur in soil.

Processing technology of sulfur coated urea in NPK fertilizer production line

Urea particles are heated by a heater and then coated with a sulfur-containing outer film. After urea coating, it is sent to powder machine by large angle belt conveyor. The powder machine sprays particles to seal the cracks of the coating and reduce the biodegradation of the sulfur coating. Two series of machines are used to ensure the quality of fertilizer. The coating of NPK fertilizer production line on the outer layer of urea ensures the slow release of fertilizer efficiency.

The outer envelope provides a physical barrier for urea, so that urea is slowly permeated by water and decomposed by microorganism. In the soil environment, urea gradually diffuses through the envelope, and releases nutrients slowly through the envelope cracks and the structure formed naturally on the envelope surface.

Fertilizer Coating Process

Coated fertilizer is a kind of NPK compound fertilizer widely used in agricultural production. It is popular with farmers for its low cost and high fertilizer efficiency. When NPK chemical fertilizer production line produces compound fertilizer, the treatment of coating machine is increased, which greatly improves the influence of fertilizer on crops.

The controlled release time of coating controlled release fertilizer is long, and the fertilization effect can be as long as 2 months to 1 year. NPK coated fertilizer can promote root growth, make crops mature early, solve the problem of crop fertilizer shortage caused by severe drought, and create favorable conditions for high yield of various crops.

NPK coated fertilizers can be used in the production of many crops. The output of rice, wheat, peanuts, corn, cotton, tobacco, vegetables, fruit trees, flowers, lawns and other crops increased significantly.

How to process NPK fertilizer production line

In the process of coating fertilizer, NPK fertilizer production line uses various nutrients, such as blood acid as coating layer, and the fertilizer is coated by coating machine. The coating can greatly reduce the loss of fertilizer and soil fixation, and greatly improve the utilization rate of fertilizer. The proportion of NPK and its trace elements in coated fertilizer processed by NPK fertilizer production line is determined according to crop demand and different soil conditions.

When we use NPK fertilizer production line to process coated fertilizer, we can produce special or general coated compound fertilizer for crops. This special NPK compound fertilizer has high fertilizer efficiency.

The application amount should be reduced according to the specific situation of crops and soil. The time interval of fertilization should be determined according to the length of controlled release cycle.

Therefore, when farmers use coated compound fertilizer, the production cost will be reduced.

How to make organic compost fertilizer at industrial scale?

Composting process is to reduce moisture and decomposition odor through decomposition and fermentation, so that manure can be used. Organic fertilizer equipment for composting livestock manure, not only can eliminate odor, but also can be used in agricultural production, provide nutrients for crops, and greatly improve crop income.

Compost fermentation, temperature rise, make it harmless. The feces of livestock and poultry contain pathogenic bacteria, parasite eggs and weed seeds. Compost is treated by organic fertilizer equipment system, and harmful substances are destroyed by the rise of fermentation temperature. During the composting process, the temperature of the fermentation product continuously rises to 70 ° C, which is enough to kill pathogens and parasites.

Compost fermentation requires oxygen for microbial activities. We can use composting turning machines with organic composting equipment to mix materials, increase material air and increase the gap between fermented materials.

The compost is sent to the hopper, and the screening material of drum screen is crushed by the chain crusher, which is the finished composting product.

Urea fertilizer coating

With the continuous improvement of agricultural science and technology, the promotion of high-yield varieties, the improvement of land re cultivation index, the vigorous development of economic crops, flowers and urban greening. The phenomenon of crop growth and soil nutrient ecological balance is becoming more and more serious, and the phenomenon of crop sulfur deficiency is becoming more and more serious.

Sulfur urea has become a popular fertilizer product in the market. It is coated with sulfur and other trace elements on the outside of urea by coater and pulverizer, so that the nutrients of fertilizer are released slowly. It is different from the technology of rotary drum granulator of compound fertilizer.

Why should sulfur coated urea fertilizer be used

1. sulfur coated urea can improve the utilization of fertilizer, similar to the granular fertilizer made by disc granulator, and can control the release rate of fertilizer nutrients. Especially, the utilization rate of nitrogen fertilizer can be greatly improved, the efficiency of fertilizer can be nearly doubled, and the agricultural investment can be greatly reduced and the environment can be protected.
2. increase crop yield greatly. The application of different soil and crop has a good effect on the yield.
3. the sulfur coated urea fertilizer can improve the quality of the crop products.
4. fertilizer can be used as soil conditioner, and the effect of the treatment of saline alkali land is good.
5. reduce labor input.

The application of sulfur coated urea fertilizer at one time can meet the needs of different growth stages of crops. With the high cost and shortage of modern agricultural labor cost, the application of sulfur coated urea in some crops also shows its characteristics.

For example, planting sugarcane, because the cane grows for months, it is not easy to mechanized fertilization after the crown is closed. In the early stage of self-growth, single fertilization can meet the needs of crops and is welcomed by sugarcane farmers. Strawberries grown in plastic mulch are also easy to apply nitrogen, so 70 percent of California’s strawberry growers use sulfur coated waste.

We provide a complete production line of sulfur coated urea, as well as the chemical fertilizer production equipment such as disc granulator, drum granulator, double roller granulator, coating machine, packaging machine and so on.

How to make granules fertilizer with pan granulation machine?

Organic-inorganic compound fertilizer is a compound fertilizer that integrates organic matter and inorganic fertilizer. Organic-inorganic compound fertilizer has various components, which can not only provide crop nutrients, but also improve soil biological activity and soil fertility, so it is widely used in cash crops.

Organic matter is an important component in organic-inorganic compound fertilizer, and its content directly determines the actual effect of bio-organic compound fertilizer. Therefore, the granulation process of organic-inorganic compound fertilizer production line is particularly important. The organic fertilizer disc granulation production line can realize the complete treatment of organic-inorganic compound fertilizer.

For the pan granulator, the addition of organic matter is also the key to granulation. Want to know how does the granulator make fertilizer granules by wet granulation method, welcome to https://www.fertilizermachinesale.com/pan-granulation-process/

According to the actual situation, several kinds of materials with abundant raw materials, low price and convenient processing can be selected as the raw materials of the pan granulator.

Organic fertilizer: chicken manure, pig manure, peat, plant ash, etc.
Inorganic fertilizers: urea, ammonium sulfate, superphosphate, calcium magnesium phosphate, potassium sulfate, potassium chloride, etc.

Organic compound fertilizer disc granulator

Organic fertilizer has strong water absorption and looseness, and its water content, fineness and other factors have a greater impact on granulation. Therefore, organic matter plays an important role in the production of disc granulators. On the premise of keeping the compound fertilizer and other inorganic nutrients unchanged, increasing the input of organic matter is an important way to improve the quality of biological compound fertilizer.

However, organic matter has strong dispersibility and has a greater impact on granulation. The organic content is too high, which is not conducive to the production of the pan granulator.

Experiments show that in the production line of organic fertilizer disc granulation, the amount of organic matter is about 25%-35%, and a better granulation effect can be obtained. The process of organic fertilizer disc granulation production line is suitable for the production of granular organic-inorganic compound fertilizer.

How to buy quality produced compound fertilizer products?
