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.

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.
