Burnt Lime Stone by Rama Lime Industries: A High-Quality Solution for Steel, Construction, and Chemical Industries

Among the essential raw materials that drive industrial development, Burnt Lime Stone (also known as Quicklime or Calcium Oxide – CaO) stands as one of the most fundamental and versatile. Its unique chemical and physical properties make it indispensable across metallurgical, chemical, construction, and environmental applications.

At Rama Lime Industries, we take immense pride in being a leading Manufacturer and Wholesale Supplier of high-quality Burnt Lime Stone in India. Our decades of experience, advanced calcination facilities, and commitment to precision have made us a trusted name for industries seeking consistent quality and dependable performance.

Understanding Burnt Lime Stone (Quicklime)

Burnt Lime Stone is produced by heating natural limestone (CaCO₃) at controlled high temperatures between 900°C and 1200°C — a process known as calcination. During this process, carbon dioxide is released, transforming limestone into Calcium Oxide (CaO).

Chemical Reaction:
CaCO₃ (Limestone) → CaO (Quicklime) + CO₂ (Carbon Dioxide)

This conversion enhances the reactivity of the material and changes its crystalline structure. The resulting Burnt Lime Stone becomes a powerful alkaline compound capable of neutralizing acids, purifying metals, and serving as a base material for numerous chemical reactions.

Manufacturing Process at Rama Lime Industries

Being a trusted Manufacturer of Burnt Lime Stone, Rama Lime Industries follows a highly monitored and quality-oriented production cycle. Each stage — from raw material selection to final packaging — is conducted under expert supervision and in compliance with international standards.

1. Raw Material Procurement

We source only high-grade limestone with minimal silica and magnesium impurities from reliable quarries. The stones undergo chemical and physical evaluation to ensure ideal calcination performance.

2. Crushing & Sizing

The raw limestone is crushed into consistent sizes to facilitate uniform heating and proper gas circulation during calcination.

3. Calcination Process

Using modern vertical shaft kilns and rotary kilns, the crushed limestone is heated to the precise temperature where carbon dioxide is expelled. This ensures complete transformation into calcium oxide without over-burning.

4. Cooling & Stabilization

The freshly burnt lime is cooled in controlled conditions to prevent hydration and maintain structural integrity.

5. Screening & Grading

The cooled lime is screened and graded into different size fractions (0–10 mm, 10–25 mm, 25–50 mm, etc.) according to customer specifications.

6. Quality Control

Each batch undergoes rigorous chemical composition analysis — focusing on CaO content, reactivity, bulk density, and moisture. Our in-house lab ensures that all standards meet customer and industry requirements.

7. Packaging & Delivery

As a reputed Wholesale Supplier, we provide Burnt Lime Stone in HDPE bags, jumbo sacks, or loose bulk depending on client needs, ensuring safe transit and storage stability.

Frequently Asked Questions (FAQ):

1. What is Burnt Lime Stone used for?

Burnt Lime Stone (Quicklime) is widely used in steelmaking, construction, sugar refining, water treatment, and chemical manufacturing due to its reactivity and ability to neutralize impurities.

2. Is Burnt Lime Stone the same as Hydrated Lime?

No. Burnt Lime (CaO) is anhydrous, whereas Hydrated Lime (Ca(OH)₂) is produced by adding water to Quicklime. Each serves different industrial purposes.

3. How should Burnt Lime Stone be stored?

It should be stored in dry, airtight containers or moisture-proof environments. Exposure to air or humidity can cause it to react and lose reactivity.

4. What is the shelf life of Burnt Lime Stone?

When stored correctly in a moisture-free environment, its shelf life is approximately six months, maintaining high reactivity and stability.

5. How does Burnt Lime improve steel quality?

By absorbing phosphorus, sulfur, and silica impurities, Burnt Lime ensures cleaner, stronger, and more durable steel outputs.
