Spillage of high-temperature bulk material lifting: Cement plants use TH ring chain bucket elevator for suitable working

Common Pain Points of Vertical Conveying for High-Temperature Bulk Materials in Cement Plants
In cement production, vertical lifting of powder from kiln systems and by-product clinker powder creates challenges for conveying system design. These materials can reach up to 250℃. Ordinary conveying equipment often suffers from material spillage during discharge, thermal deformation of traction parts and unstable output.
Many conventional bucket elevators use belt traction. Belts age rapidly under high temperature, leading to frequent maintenance. Some units only support one discharge method, which fails to fit the flow property of cement powder. Material overflow causes dust, raw material loss and extra maintenance workload for plants.
For cement plant engineers, equipment must meet three requirements: temperature resistance, suitable discharge mode and stable conveying. Technical parameter matching is the core of equipment selection.

Structure & Working Condition Adaptation of TH Ring Chain Bucket Elevator
The TH ring chain bucket elevator uses forged ring chains as traction components with double chain layout and intermittently mounted buckets. It supports mixed discharge or gravity discharge, different from the centrifugal discharge design of HL type. It can handle materials with temperature below 250℃, matching the temperature limit of high-temperature powder in cement production.】

TH series provides two bucket types: ZH medium deep bucket and SH deep bucket for different throughput demand. Models range from TH160 to TH800, with capacity from 10 to 235 m³/h. Bucket speed is between 1.4 m/s and 1.6 m/s. Low operating speed helps reduce powder spillage.
Compared with belt traction, forged ring chains perform better under high temperature, suitable for long-time continuous industrial operation and lowering the failure risk of traction parts.

Selection Guidelines for Cement Plants

Match Discharge Mode with Material Property
Cement powder has medium flowability. Mixed and gravity discharge of TH elevator delivers gentler material release and reduces spillage. For powder with better flowability, HL centrifugal discharge can be considered as an alternative.

Select Model According to Production Capacity
Match the model and bucket type based on designed output. SH deep buckets are selected for higher throughput; ZH medium deep buckets are preferred for high powder ratio scenarios to control spillage.

Temperature Limit Control
This elevator is designed for material temperature below 250℃. If material temperature exceeds this limit, pre-cooling process is required to prevent accelerated wear of chains and buckets.

Conclusion
To solve spillage problems during vertical lifting of high-temperature bulk material in cement plants, TH ring chain bucket elevator is a practical option with forged ring chain structure, multiple discharge options and clear temperature rating. When selecting equipment, engineers should check not only conveying capacity, but also material temperature, flow property and discharge requirements to align equipment parameters with site conditions.
