TB/ TD/ TH Bucket Elevators: Characteristics, Advantages, and Applications
Author :
In the realm of industrial vertical conveying, TB, TD, and TH bucket elevators are widely used core equipment. The primary differences among these three types stem from their traction components—chain plates, belts, and round chains, respectively. This key distinction directly affects their wear resistance, load-carrying capacity, and suitability for different materials. Therefore, selecting the right type requires a precise match with material characteristics and working conditions to ensure efficient conveying and equipment stability.

Introduction, Advantages, and Applications of Each Type
TB Chain Plate Bucket Elevator
Structure: The TB chain plate bucket elevator uses high-strength chain plates as the traction component, with the buckets rigidly connected to the chain plates. This design ensures extremely high stability during operation, minimizing the risk of bucket loosening or displacement.
Performance Advantages: The chain plate material endows the equipment with excellent wear resistance, enabling it to withstand the long-term impact of highly abrasive materials.
It also boasts outstanding load-carrying capacity, capable of handling high-volume material conveying.
Additionally, its high-temperature resistance allows stable operation at temperatures up to 250℃. The equipment has a long service life and low maintenance costs.
Applications: The TB chain plate bucket elevator is suitable for conveying highly abrasive, high-temperature lumps or granular materials.
For example, it is used in the mining industry for ores, in the metallurgical industry for coke, and in the cement production process for cement clinker. It can meet the efficient conveying needs of these demanding materials.
TD Belt Bucket Elevator
Structure: The traction component of the TD belt bucket elevator is a rubber belt, with the buckets fixed to the belt via bolts. This unique belt traction design results in significantly lower noise levels during operation, creating a quieter working environment.
Advantages: The overall structure is lightweight, making installation and commissioning easier and saving time on initial construction.
The operation is smooth, reducing the risk of material spillage during conveying.
The manufacturing cost is relatively low, making it suitable for budget-limited or low-load conveying scenarios.
It also has low energy consumption, reducing long-term energy costs, especially for continuous, low-load conveying conditions.
Applications: Its application scope is mainly focused on conveying powdery or granular materials with little or no abrasiveness.
For example, it is used in the grain processing industry for flour and grains, in the building materials sector for cement powder, and in some chemical industries for light powdery materials. It is important to note that this equipment can only be used in environments where the material temperature is ≤120℃, and the working conditions must be strictly controlled.
TH Round Chain Bucket Elevator
Structure: The TH round chain bucket elevator uses a round chain as the traction component, with the buckets firmly connected to the chain. This structural design gives the equipment an extremely high load-carrying capacity, allowing it to easily handle heavy-load material conveying tasks without chain breakage or bucket detachment even under high-intensity working conditions.
Performance: The TH round chain bucket elevator has high tensile strength, capable of withstanding significant material weight impacts.
It also has good wear resistance, with slow chain wear when conveying abrasive materials.
It also has high-temperature resistance and can operate normally in environments up to 250℃, making it suitable for heavy-load, high-demand industrial conveying scenarios.
Applications: In practice, it is mainly used for conveying highly abrasive, high-density lumps.
For example, it is used in the coal mining industry for raw coal, in stone quarries for crushed stone, and in the metallurgical industry for ore raw materials. It can maintain stable performance in complex, high-intensity conveying conditions.

Conclusion
In summary, TB, TD, and TH bucket elevators each have their unique characteristics and advantages, making them suitable for different industrial conveying needs. Proper selection based on specific material and working conditions is crucial for achieving efficient and stable conveying operations.
