Roary Dryer for Efficient Fertilizer Production

Rotary dryer is the main energy consuming equipment in organic fertilizer production line. Only when the dryer reaches the operation state of high quality, high yield and low consumption, can the loss be reduced and the production income be maximized. The traditional rotary dryer has been in a low efficiency working state: low output, high energy consumption, low thermal efficiency, high water content and difficult to control.

From the perspective of the optimization of the rotary dryer itself, the efficiency of the organic fertilizer production line can be improved by improving the performance of the dryer itself.

Our factory has designed a combined lifting plate dryer, which avoids many disadvantages of the traditional rotary dryer. There are many problems in the structure of traditional drum dryer, which affect the drying effect.

The material dispersion of traditional dryer on the cross section of cylinder is low. The lifting plate installed on the dryer forms a wind tunnel on the cylinder section, and the materials are only distributed in part of the space. When the material falls, it will accumulate on the L-shaped lifting plate for a period of time. Only the surface material is in contact with hot air, and the material in the reactor cannot be in contact with hot air. Therefore, the dispersion of the material on the cross section is low and cannot be in full contact with hot air.

The traditional rotary dryer has a wind tunnel from front to back. The front and rear of the oil cylinder are equipped with lifting plates of the same specification. The wind tunnel will extend from the feed end to the tail. Some hot air cannot exchange heat and is discharged directly through the wind tunnel.

The new rotary dryer adopts a combined lifting plate, which improves the dispersion of materials on the cross section of the cylinder, reduces the front and rear wind tunnels, improves the heat transfer efficiency of fertilizer particles and reduces the energy consumption of the organic fertilizer production line.

Fertilizer Drying Process in Granulation Plant

The dryer of organic fertilizer production process equipment is mainly used for drying organic fertilizer in the production line. In fertilizer processing, the dryer uses the dryer and hot blast stove for heat circulation heat exchange, which can quickly realize material drying, drying cooling and coating, and can directly package organic fertilizer. The dryer can not only remove the water in the organic fertilizer, but also sterilize and deodorize to avoid the deterioration of the organic fertilizer during storage and transportation. This is also one of the important process steps in the production of organic fertilizer.

1. Safe, some dust and some organic fertilizer raw materials will be produced in the process of organic fertilizer processing. After decomposition of organic fertilizer, some residues are flammable, explosive and easy to oxidize. Therefore, safety should be considered when selecting heat source. When using direct combustion source, flame retardant or explosion-proof measures shall be taken.

2. Stability, ensure the drying quality of the organic fertilizer dryer, and then analyze the heating temperature and purity of the heat source of the dryer to ensure that the heat source can easily meet the quality of dried materials and dried materials, so as to achieve the stability of the operation of the organic fertilizer dryer.

3. Environmental protection and reduce environmental protection expenditure in the process of organic fertilizer processing. When burning materials, it will produce pungent smell and emit toxic gases that pollute the environment. In order to reduce emissions, it is necessary to increase the investment of dust removal equipment. Therefore, environmental protection heat source is also to reduce the investment of environmental protection equipment.

4. Easy to collect, need to consider the convenience of the source. In order to reduce the cost of heat source, the heat source used is disorderly, which is easy to damage the drying stability of dryer equipment and heat source.

5. The dryer of organic fertilizer production equipment affects the utilization of heat source in the process of fertilizer manufacturing. Therefore, when selecting the heat source, we should select the appropriate heat source to avoid unnecessary waste and avoid blind thrift.

It can be seen from the above aspects that the selection of heat source in the drying process of dryer of organic fertilizer production equipment should comprehensively consider safety, drying cleanliness, drying stability, environmental protection and different quality of raw materials and finished products. As long as the above conditions can be fully considered, the appropriate heat source of organic fertilizer dryer can be selected, so as to realize environmental protection from the heat source, save raw materials, reduce costs, improve the drying effect of organic fertilizer and improve product quality.

Fertilizer Dryer Installation Tips

In the production line of organic fertilizer and NPK fertilizer, drum dryer is an indispensable equipment for drying treatment. When installing the dryer, the height of the near fire end is higher than that of the far fire end, which is a wrong method. The device will speed up the movement of fertilizer particles and shorten the fixed time of materials in the rotary drum of dryer. 

In this case, the lifting plate in the oil cylinder cannot be lifted normally, and the drying effect is not very good. At the same time, it will cause unnecessary trouble to the installation and operation of fertilizer equipment.

Drum dryer in chemical fertilizer production line

The dryer is usually a downstream dryer. If the steam can not be discharged in time during the drying process, the steam in the drum will run for too long, and even lead to the material fusing with moisture again. As an organic fertilizer manufacturing machine, in the installation process, a set of anti-skid supporting wheel fixed belt is used to switch on and off, so as to prevent the drying equipment from slipping during operation.
