In the lime production industry, twin-shaft lime kilns have become the global mainstream technology due to their excellent thermal efficiency, uniform lime reactivity, and low energy consumption. The reliability and precise matching of equipment systems directly determine kiln capacity, product quality, and operating costs. As a market promotion expert, we present a complete matrix of key equipment for twin-shaft lime kilns, along with a one-stop solution from engineering to core components.
| Category | Equipment | Function |
|---|---|---|
| Charging System | Disc Distributor, Rotary Distributor | Even distribution of limestone across kiln cross-section, preventing segregation |
| Flue Gas / Combustion Gas Valves | All Type Directional Valve of Flue Gas, Combustion Gas Valve Series | Precise control of gas flow direction, supporting reversing calcination process |
| Coal Injection & Metering | Coal Ball Valve, Coal Metering Valve, Coal Y Valve, disc distributor | High-accuracy feeding, shut-off, and switching for stable fuel supply |
| Combustion System | Burner Lance | Multi-stage adjustable flame shape for different fuels and loads |
| Discharging System | Lime Discharging Valve | Continuous or intermittent discharge, maintaining stable bed level |
| Sealing System | Sealing Valve | Prevents gas leakage, maintains kiln pressure and atmosphere |
| Heat Exchange | Heat-Exchanger Cylinder | Recovers waste heat, improves thermal efficiency (custom design & manufacturing available) |
| Engineering & Refractories | All Engineering, Critical Bricks | Full-cycle service from design to commissioning; various materials/OEM critical bricks |
Our equipment is engineered for seamless integration with the following kiln configurations:
Twin-O (circular twin-shaft kiln)
Twin-D (D-shaped twin-shaft kiln)
Twin-Rectangular (rectangular twin-shaft kiln)
Equipment interfaces, control logic, and refractory designs are optimized for each kiln type to ensure installation accuracy and operational stability.
Our key equipment supports twin-shaft lime kilns from 200 tpd to 900 tpd. Through modular design and adjustable actuators (metering valves, burner lances, etc.), the same equipment family can serve small premium lime lines up to large-scale production plants with flexible capacity upgrades.
The heat-exchanger cylinder is a core component for improving thermal efficiency in twin-shaft kilns. We offer in-house design + manufacturing capabilities:
CFD simulation optimization based on your flue gas temperature, flow rate, and dust characteristics
Selection of high-temperature resistant, corrosion-resistant alloys or composite structures
Replacement of existing low-efficiency heat exchangers – energy savings of 8%–15%
Material options: High-chrome wear-resistant cast iron, heat-resistant stainless steel, ceramic-lined, silicon carbide composites, etc.
OEM service: Drawing confirmation, reverse engineering, batch customization
Critical bricks: Magnesia bricks, high-alumina bricks, silicon-mullite bricks, etc., compatible with both domestic and imported kilns
Systematic supply: Valves, lances, heat exchangers, refractories – one-stop procurement
Technical compatibility: Field-proven with global mainstream twin-shaft kiln designs
Engineering services: Installation guidance, commissioning, spare parts forecasting, and lifecycle maintenance
