Our vertical lime shaft kiln is a modern steel-structured furnace engineered for high-efficiency lime calcination, employing counter-current heat exchange technology (material descends while hot gases ascend) to achieve superior thermal performance compared to traditional rotary kilns. This eco-conscious design repurposes waste gases—such as converter gas, blast furnace gas, and carbide tail gas—as fuel while minimizing emissions through clean combustion technology. With a daily capacity ranging from 50 to 400 tons (customizable), the kiln delivers operational excellence via automated control systems that ensure precision, stability, and reduced labor costs, alongside 20–30% lower fuel consumption than conventional kilns. Economically advantageous, it significantly cuts production costs by utilizing low-cost or waste-derived fuels and offers an extended service life thanks to its robust steel construction.

✔ Application

Our lime shaft kilns are extensively applied in:

1. Metallurgy – Steelmaking, ironmaking, and non-ferrous metal processing

2. Building Materials – Cement, glass, and lime-based products

3. Chemical Industry – Calcium carbide and nano calcium carbonate production

4. Construction – Aerated concrete blocks and lightweight materials

5. Food Processing – Sugar purification and water treatment

Designed for cross-industry adaptability, our kilns deliver high-purity lime to meet diverse industrial demands.

✔ Advantages

1. The kiln has great flexibility in operation, and can be adjusted from 60-100% to achieve stable production;

2. Applicable fuels are solid fuels such as coke and anthracite;

3. Low heat consumption and reasonable use of heat energy. The secondary high-temperature air preheated by cooling lime directly participates in combustion;

4. The vertical kiln adopts micro-negative pressure operation (kiln top) to make the airflow in the kiln evenly distributed, which is conducive to the calcination of lime.
