Quick Lime Lumps
Engineered for superior reactivity in metallurgical, chemical and environmental applications. Available in soft, medium and hard burnt grades with custom sizing from 20mm to 50mm.
Product Overview
Manufactured from premium-grade limestone in vertical shaft kilns at 900-1200°C, our Quick Lime Lumps deliver consistent chemical composition and reactivity. Each batch undergoes rigorous quality testing for free lime content, impurity levels and structural integrity.
- High Active CaO (85-94%) - Maximum process efficiency
- Low Impurities - SiO₂ <1.5%, Fe₂O₃ <0.5%, MgO <1.0%
- Controlled Burn Grades - Soft, medium and hard burnt available
- Custom Sizing - 20mm to 50mm grading per your process
Industrial Applications
Trusted across heavy industry and environmental sectors
Steel & Metallurgy
Flux in BOF/EAF for slag conditioning, desulfurization and dephosphorization of molten steel. Ensures low sulfur content and improved metal quality in continuous casting operations.
Non-Ferrous Metals
Used in copper and zinc smelting for slag formation and impurity removal. High reactivity quick lime lumps ensure efficient metal recovery and cleaner refining operations.
Chemical Manufacturing
Base for calcium carbide, bleaching powder, PCC and other calcium-derived intermediates. High CaO content ensures superior yield and consistent reaction efficiency.
Sugar Refining
Quick lime lumps are slaked to produce milk of lime for juice clarification in sugar mills. Proper reactivity ensures efficient defecation and higher sugar recovery rates.
Paper & Pulp
Kraft pulping causticization and bleaching for high-brightness paper production. Converts green liquor to white liquor, enabling closed-loop chemical recovery.
Glass Manufacturing
Quick lime lumps serve as a source of calcium oxide in glass batch formulations. Provides chemical durability, thermal stability and improved hardness in the finished glass product.
Also used in: Water Treatment, Agriculture & Soil Treatment, Mining & Ore Processing, Refractory and more.
