Drying Process in Fertilizer Production

With the development of economy, the agricultural industry is also developing, driving the development of some agricultural equipment. The dryer of organic fertilizer production line is one of them. The rotary drum dryer has reasonable design, excellent production performance, advanced technology, high output and small floor area.

The technology and adaptability of bio organic fertilizer dryer are constantly improved.

The dryer with electricity as fuel has environmental protection technology. The smaller, the more uniform. This is a better dryer. Fuel makes fuel fuller and dry material better. But in this case, the cost of fuel will increase. Therefore, some customers add the quality of this coal to some inferior coal, which can reduce the investment cost. However, in this case, the temperature in the machine will fluctuate and uneven, which will affect the quality of the dried material and achieve the desired effect, so it is not worth paying for this.

But we have to add inferior coal. Experts said that some inferior coal can be added to high-quality coal, but not too much, so the consequences are not obvious and fuel costs can be saved. Therefore, the use of coal as fuel drying equipment, the correct use of coal will produce unexpected results.

Rotary drum dryer is a special drying equipment with high moisture content, high viscosity, high water holding capacity and low calorific value specially designed for NPK fertilizer production process. The internal structure of the dryer has been specially designed, which not only improves the thermal efficiency, but also has the advantages of simple process design, low investment and operation cost. It is more suitable for users who need long-term storage of the granules treated by drum granulator

Increasing the inlet air temperature of the dryer can improve the thermal efficiency of the dryer, and the inlet air temperature is limited by the allowable temperature of the product. In the parallel flow particle suspension dryer, the surface temperature of the particles is low, so the inlet temperature of the drying equipment may be much higher than the allowable temperature of the product.

How to get compound fertilizer granules dried?

In the process of compound fertilizer production line, the material must be dried and cooled. At this point, a dryer, cooler and screening machine are required. Many customers are not familiar with chemical fertilizer processing technology. Here is how to dry and cool the materials in theĀ  fertilizer production line.

The particles to be dried processed by NPK fertilizer granulator are transported to the feed port of the feeder through the belt conveyor, and the granular materials flow into the drying cylinder along the feed trough. The feeder is mounted outside the drying cylinder.

Driven by the deceleration drive system, the granular material moves backward with the rotation of the drying cylinder, and the heated hot air is blown into the feed end. It directly contacts the material of the drying cylinder, evaporates its water vapor and dries it.

In the drying process, according to the drying degree of the material, the deceleration drive system can adjust the speed through the frequency converter.

The intermediate sensing draft hood draws steam from the drying cylinder. Then, as the drying material rotates, it enters the cooler again. Under the action of the middle induction draft hood, the natural wind enters the cooler from the unclosed end.

As the cooler rotates, the material is picked up and the material temperature is directly reduced to the natural temperature. After that, the granular material will enter the drum screen, and the unqualified material will be screened out from the drum screen, and the qualified material will go directly to the next packaging part.
