QUICK LIME LUMPS 0-25 MM

Quick Lime Lumps 0–25mm (Calcium Oxide – CaO)
Other names: Burnt Lime, Calcined Lime, Unslaked Lime
Manufacturer: Vietnam Technology Mineral JSC

Description:
Quick Lime Lumps 0–25mm are produced by calcining selected high-purity limestone (CaCO₃) in modern rotary kilns at high temperatures. This process drives off carbon dioxide (CO₂) to form calcium oxide (CaO):
Reaction: CaCO₃ → CaO + CO₂

This product is supplied in lump form with particle sizes from 0 mm to 25 mm, ideal for various industrial and chemical applications requiring strong reactivity and controlled handling. When mixed with water, it reacts exothermically (slaking of lime), releasing significant heat. With a high alkaline pH (~12.5), it is highly caustic and must be handled with proper safety precautions.

Key Specifications:

• CaO content: ≥ 90% for premium-grade quality

• Size range: 0–25 mm (screened and graded)

• Moisture content: ≤ 1–2% to ensure optimal reactivity

• Impurities: MgO ≤ 2.5%; negligible heavy metals (Pb, As)

• Density & Consistency: Uniform lump quality, density, and burning degree

• Reactivity: Fast, exothermic reaction upon slaking; ideal setting time ~24 hours

• Storage stability: Maintains performance for 6–12 months with proper storage

• Source traceability: Produced from carefully selected limestone with consistent kiln control

Applications:
Quick Lime Lumps 0–25mm are widely used in:

• Metallurgy: Steel refining, non-ferrous metal smelting

• Construction: Soil stabilization, mortar production, hydrated lime manufacturing

• Water Treatment: pH adjustment, softening, removal of impurities

• Chemical Industry: Production of calcium carbide, soda ash, bleaching powder

• Paper & Pulp: Kraft process causticizing and pulp digestion

• Environmental Uses: Flue gas desulfurization, acidic waste neutralization

• Agriculture: Soil conditioning, pest & odor control

Production Advantage:
Manufactured in modern rotary kilns for consistent burning, high reactivity, and uniform lump size distribution.
