Product Advantages
1. High Reactivity Lime Output
The vertical kiln design ensures uniform calcination, producing quicklime with activity levels reaching 300-380ml. This high-reactivity lime is ideal for steelmaking, flue gas desulfurization, and other demanding industrial applications.
2. Energy Efficient Operation
With advanced heat recovery and insulation systems, the kiln achieves low heat consumption below 4600 kJ/kg. The vertical configuration allows optimal heat exchange between flue gases and raw materials, significantly reducing fuel costs over the kiln's lifetime.
3. Fully Automatic Control System
-
PLC/DCS intelligent control with centralized operation from a control room
-
Siemens intelligent weighing module for precise batching and compensation
-
WINCC human-machine interface (HMI) for real-time monitoring and data logging
-
Automatic temperature, pressure, and material level control ensures consistent product quality
4. Environmental Compliance
The kiln is equipped with advanced dust collection and flue gas treatment systems, achieving emission concentrations below 30mg/Nmยณ. This meets strict environmental standards and supports sustainable production practices.
5. Multi-Fuel Flexibility
The kiln can be designed to operate on various fuel types, including low-cost industrial tail gases (blast furnace gas, converter gas, calcium carbide tail gas), natural gas, coal, or petcoke โ turning waste into wealth where tail gases are available.
6. Compact Footprint & Low Investment
Compared to rotary kilns, the vertical shaft design requires less land area and involves lower capital investment, making it an ideal choice for small to medium capacity requirements. The simple mechanical structure also results in lower maintenance costs.
7. Long Service Life
The kiln features high-quality refractory lining and wear-resistant components, providing a major overhaul cycle of 3-5 years and reducing long-term maintenance expenses.
8. Reliable Operation with Multiple Safety Features
-
Automatic alarm and shutdown systems for abnormal conditions
-
Pressure-relief and anti-blockage designs
-
Redundant systems for critical components ensure continuous production
Applications
The 50TPD vertical lime kiln is suitable for producing high-quality quicklime used in:
| Industry | Application |
|---|---|
| Steel & Metallurgy | Flux agent for steelmaking, slag conditioner |
| Environmental Protection | Flue gas desulfurization (FGD), water treatment |
| Chemical Industry | Calcium carbide production, precipitated calcium carbonate |
| Construction | Aerated concrete blocks, mortar, plaster |
| Sugar Refining | Juice purification in sugar beet/cane processing |
| Paper Industry | Pulping chemical recovery |
