Rotary Dryer

High-quality Fly ash dryer manufacturer

Tongli fly ash dryer is an industrial equipment specially used for processing fine particle materials such as fly ash. Fly ash is the fine ash produced after burning coal in thermal power plants. It usually contains a high moisture content and needs to be dried for further use or safe disposal. The thermal efficiency of Tongli fly ash dryer can reach 70% to 85%. The operating temperature inside the equipment is usually between 200°C and 600°C, depending on the heat source and the nature of the fly ash. Fly ash dryer is particularly suitable for processing large amounts of fly ash produced by thermal power plants and steel mills. The dried fly ash can be used to produce building materials such as cement, concrete, and wall materials.

FAQ

1. How to maintain the fly ash dryer?

Regularly check the operating status of the equipment, including the motor, transmission system, drum, fan and other parts to ensure that all parts are operating normally without abnormal noise or vibration.

Regularly clean the dust, dirt and accumulated materials inside and outside the equipment, especially the dust collector, air duct, screen and other parts to avoid dust accumulation affecting the performance of the equipment.

Check the wear of the drum lining, especially the wear-resistant materials (such as wear-resistant bricks or linings), and regularly replace damaged or worn parts to maintain the drying efficiency of the equipment.

Establish equipment maintenance and overhaul records, including the time, content, problems found and handling of each maintenance, so as to facilitate tracking of the equipment's usage status and maintenance history.

2. How to increase the output of fly ash dryer?

Increase the heat source temperature: Increase the heat source temperature in the dryer, increase the heat supply, and make the fly ash evaporate water faster, thereby improving the drying efficiency and output.

Optimize the feed speed and amount: Adjust the feed speed and feed amount according to the actual situation of the dryer to ensure that the material can fully contact the hot air in the dryer without affecting the drying effect due to excessive feed.

Increase the air flow speed: Properly increasing the air flow speed in the dryer will help speed up the evaporation of water in the fly ash and accelerate the movement of the material, thereby shortening the drying time and increasing the output.

Use pretreatment process: Perform appropriate pretreatment before the material enters the dryer, such as dehydration or preheating, to reduce the initial moisture content of the material, thereby improving the drying efficiency.

3. How does a fly ash dryer work?

Wet fly ash is fed into the feed end of the dryer through a feeding device (such as a screw conveyor or bucket elevator). The feeding system ensures that the material is evenly fed into the dryer. Hot air enters the dryer through the air duct system and comes into direct contact with the fly ash.

The temperature of the hot air is usually between 200°C and 600°C, depending on the characteristics and requirements of the material. The fly ash is constantly turned and stirred in the rotating dryer drum. This tumbling motion allows the fly ash to fully contact the hot air, improving the heat exchange efficiency.

The heat in the hot air causes the moisture in the fly ash to evaporate rapidly. The water vapor is carried away from the fly ash, leaves the surface of the material, and enters the air flow inside the dryer.

The dried fly ash is discharged at the end of the dryer through a discharging device (such as a screw conveyor, vibrating conveyor or air flow conveying) and enters the downstream storage or processing system.

4. What are the common problems of fly ash dryer?

The material is blocked at the feed port, drum or discharge port, affecting production efficiency. Possible reasons:

1. The material humidity is too high, resulting in agglomeration or adhesion.

2. The internal design or size of the equipment is not matched, affecting the flow of materials.

The conveying system is faulty or blocked. Solution:

1. Control the moisture content of the material to avoid agglomeration caused by excessive humidity.

2. Regularly check and maintain the internal structure of the equipment to ensure reasonable design.

3. Check and repair the conveying system to ensure its normal operation

What is the applicable scope of fly ash dryer?

Building materials industry: fly ash is an additive for building materials such as concrete, mortar, bricks, etc. After drying, fly ash is easier to mix with other materials to improve the performance and stability of the product.

Cement industry: In the process of cement production, fly ash can be added to cement as an admixture. By drying, the moisture in fly ash can be reduced and the quality and strength of cement products can be improved.

Power industry: Thermal power plants produce a large amount of fly ash. After drying, the volume can be reduced, which is convenient for storage and transportation. At the same time, it can also meet the requirements of reuse, such as preparing cement and concrete.

Mining industry: In some mining industries, fly ash can be used as a filling material or geological reinforcement material for tailings. After drying, its performance can be improved.

Chemical industry: Fly ash can be used as raw material or auxiliary material in the production of some chemical products. After drying, fly ash has better reactivity and stability.

Agricultural field: After drying, fly ash can be used for soil improvement, as a fertilizer or soil conditioner, to improve soil structure and increase crop yields.

Will the fly ash dryer be affected by the climate?

At a lower ambient temperature, the temperature difference between the inside and outside of the dryer is smaller, and the heat loss is relatively large, which will lead to a decrease in drying efficiency, increase drying time, and thus affect the output. At a higher ambient temperature, the drying efficiency will be relatively improved.

Therefore, we add an insulation layer to the outer shell of the dryer to reduce heat loss. In a high humidity environment, the water vapor content in the air is high, and the wet air is difficult to discharge during the drying process, which affects the drying speed of the fly ash.

In addition, high humidity may also cause the fly ash to absorb more moisture before drying, increasing the difficulty of drying. If conditions permit, you can choose to carry out the drying operation in a closed environment to reduce the interference of climatic factors. Through these means, the stable operation and efficient output of the fly ash dryer can be maintained under different climatic conditions.
