Working Principle of TH-Type Bucket Elevator
The TH-type bucket elevator operates on a continuous vertical conveying system using metal chains with attached buckets. Material is loaded into the buckets at the bottom inlet through gravity or forced feeding. As the driven sprocket rotates, the chain-and-bucket assembly moves upward within a sealed casing, preventing dust leakage. At the top, material is discharged primarily by centrifugal force (for fine powders) or gravity (for larger lumps) into the outlet chute. The empty buckets then descend along the return side to complete the cycle. Key features include high-strength forged chains for heavy loads, wear-resistant buckets, and fully enclosed design for dust control. Typical speed ranges from 0.8–1.5 m/s, with capacities up to 365 m³/h depending on model size.
