The TH-type bucket elevator is a high-capacity conveying system that offers nearly double the conveying capacity compared to the HL-type of the same model. It provides convenient replacement options, resulting in cost savings. The bucket elevator features modular sprockets, where the wheel body and rim are connected with high-strength bolts. When the sprocket wears out, the rim can be easily replaced by simply removing the bolts, reducing maintenance costs.
With low noise levels, the TH-type bucket elevator meets current environmental requirements. It utilizes the ZLY-type gearbox, a newly developed hard-tooth surface reducer produced according to the ZBJI9004-88 standard. The gears undergo processes such as carburizing, quenching, and gear grinding, resulting in a compact size, lightweight, high load-bearing capacity, long service life, high efficiency, and low noise.
The transmission device is equipped with a backstop, effectively preventing "material backflow" from occurring.
The traction component consists of high-strength circular link chains made from low-alloy steel. After proper heat treatment, the chains exhibit high tensile strength, good wear resistance, and a long service life.
The TH-type bucket elevator is available in two bucket types:
ZH-type (medium-depth bucket) is suitable for conveying wet, lumpy, and difficult-to-discharge materials such as wet sand, molding sand, fertilizers, and alkali powder.
SH-type (deep bucket) is suitable for conveying dry, loose, and easily dischargeable materials such as cement, clinker, crushed stone, and coal. It also offers a higher conveying capacity than the ZH-type.
Application fields: Coal, cement, sand, clay, ore, construction materials, power generation, chemical industry, metallurgy, coal mining, light industry, and grain industries.
Applicable materials: Conveying powdery, granular, and small block materials that are non-abrasive or semi-abrasive.

Explanation: The capacity of the hopper in the table refers to the volume when it is filled with water. The conveying capacity calculated based on this hopper capacity assumes 100% filling. However, when selecting the appropriate equipment, it is necessary to refer to the table and consider the material characteristics. By determining the correction factor ψ from the table, the actual conveying capacity can be adjusted accordingly.
Table of Hopper Fill Factors
| Material characteristics | Fill factor of the material ψ | ||
| Fill factor of powder-like materials | 0.95-1 | ||
| Fill factor of granular materials below 20mm | 0.9-1 | ||
| Fill factor of small block-like materials between 20mm and 50mm | 0.8-0.9 | ||
| Fill factor of medium-sized block-like materials larger than 50mm | 0.7-0.85 | ||
| Fill factor of generally moist, slightly sticky powder and granular materials | 0.6-0.7 |
