Why choose bucket elevator to transport fly ash?

Fly ash, as a by-product of coal-fired power plants, has the characteristics of small fineness, easy dust, and certain abrasiveness, which puts forward special requirements for transportation equipment. After years of practical verification, bucket elevator has become the best solution for vertical transportation of fly ash. The main reasons include:

Excellent sealing and dustproof performance: The fully enclosed structure design effectively prevents fly ash from leaking during transportation, avoids environmental pollution, and meets increasingly stringent environmental protection requirements.

High vertical space utilization: Compared with chute or screw conveyors, bucket elevators can be arranged vertically, greatly saving plant space, and are particularly suitable for renovation projects with limited space.

Adapt to the characteristics of fly ash: In view of the fine particle characteristics of fly ash, we provide a variety of hopper options (shallow bucket, deep bucket, arc bottom bucket, etc.) to ensure efficient loading and complete unloading to avoid residue.

Wear-resistant design to extend life: Although fly ash is not as abrasive as ore, long-term transportation will still cause wear on the equipment. Our elevators are specially treated with wear-resistant steel plates or rubber linings, and the life of key components is increased by more than 30%.

Energy consumption advantage is obvious: the principle of inflow feeding and gravity unloading is adopted, which can save 40-60% energy compared with the pneumatic conveying system, greatly reducing the operating cost.

Easy maintenance: the modular design makes daily maintenance more convenient, and the combined sprocket used in the NE series can only replace the wheel rim after wear, reducing maintenance costs

Note:

The conveying volume in the table is a reference value for fly ash (bulk density of about 0.6-1.0t/m³). The actual value may vary slightly due to material properties

The lifting height can be customized according to customer needs. Special design is required for more than 30 meters

The motor power depends on the lifting height and conveying volume, which needs to be calculated and determined according to actual conditions

Special models such as explosion-proof, high temperature resistant, and corrosion-resistant can be provided

How does the fly ash bucket elevator work?

The working principle of fly ash bucket elevator is to drive the body to rotate through the drive device, so that the conveying bucket moves upward along the track of the body. The material is loaded into the conveying bucket, and as the conveying bucket rises, the material is lifted to the top and then discharged through the discharge port. Throughout the process, the guide device and anti-deviation device ensure the stable operation of the conveying bucket to prevent deviation.

What are the applications of fly ash bucket elevator?

Dahan fly ash bucket elevator has been successfully applied in many industries such as power, building materials, metallurgy, and chemical industry.
