Description:

AGICO CEMENT tailors lime processing plant solutions based on factors like capacity and budget.

1. Rotary Kiln Solution

Application: Widely used in steel, alumina, metal magnesium, etc.

Benefits: Improves steel quality, increases production, and reduces costs.

Considerations: High investment, larger area required.

2. Vertical Kiln Solution

Suitability: Small-capacity lime production, low-cost, and eco-friendly.

Operation: Material descends, and hot gas rises for lime burning.

Varieties: Twin shaft, double beam, annular vertical lime kilns available.

Competitive Advantage:

Advantages of Rotary Lime Kiln Production Line:

lEnvironmental Protection: The flue gas discharged from the vertical preheater at the kiln end has low temperature and low dust content. This simplifies subsequent flue gas treatment, meeting environmental protection requirements.

lLime Activity: The rotary kiln's open calcination, simple kiln body structure, smooth airflow, and timely discharge of sulfur-containing flue gas contribute to low sulfur content in the finished product, meeting steelmaking requirements.

lEnergy-saving: The vertical preheater at the kiln end efficiently utilizes high-temperature flue gas from calcination, significantly increasing rotary kiln output and reducing heat consumption per unit product.


Advantages of Vertical Lime Kiln Production Line:

lAdvanced Technique: Compared with the rotary kiln, the shaft kiln's lime production process is simple, with fewer moving parts and low power consumption.

lHigh Quality: The lime production line includes a jaw crusher, preventing raw burning and ensuring stable product quality. This also saves energy by avoiding excessive particle size differences.

lEnergy Efficient: More energy-efficient than other limestone firing processes, suitable for various geographic areas.
