| Automation Level | Manual or semi-automatic control | Advanced models may include PLC systems |
| Power Requirement | 15 - 30 kW | Mainly for fans & conveyors |
| Construction Material | Refractory bricks (high alumina or fire clay) | Steel shell for structural support |
| Lifetime | 5 - 10 years (with proper maintenance) | Refractory lining may need periodic repair |
Summary
A small-scale vertical shaft lime kiln is a cost-effective solution for localized lime production, with typical capacities of 10-50 TPD. Key parameters such as shaft dimensions, fuel type, and temperature control significantly influence efficiency and product quality. While these kilns are simpler than rotary kilns, proper design and operation are essential for optimal performance. Future improvements could focus on energy efficiency and emission reduction to meet stricter environmental standards.
