Hydrated Lime Manufacturer & Supplier in India

What Is Hydrated Lime?

Hydrated lime — also called slaked lime or calcium hydroxide (Ca(OH)₂) — is a fine, white, odorless inorganic powder produced by reacting quicklime (calcium oxide, CaO) with water. It is strongly alkaline, chemically stable, and easier and safer to handle than quicklime, which makes it the preferred form of lime for most industrial, agricultural, and construction applications.

Because hydrated lime reacts readily with acids, carbon dioxide, and various metal ions, it is used wherever a process needs neutralization, pH adjustment, purification, or a binding/cementing agent.

Quick facts:

How Hydrated Lime Is Manufactured

Hydrated lime is produced through a controlled chemical process called slaking, in which quicklime (CaO) is reacted with a precise quantity of water:

CaO + H₂O → Ca(OH)₂ + Heat

At Shivi Minerals, this reaction takes place in our hydration plant at Khimsar under controlled temperature and water-dosing conditions. Controlling the reaction closely is what determines the final product's quality — too little water leaves unreacted lime; too much produces a wet, lumpy product with inconsistent purity.

Our process is built around three priorities:

1. Consistent particle size — achieved through mesh-controlled milling (BSS 100 to BSS 400, depending on grade)
2. Stable chemical composition — batch testing to keep Ca(OH)₂ content within the specified purity band
3. High reactivity — critical for applications like water treatment and flue gas desulfurization, where the lime needs to dissolve and react quickly

The result is a uniform, free-flowing hydrated lime suitable for direct industrial use, with each production batch tested before dispatch.

Key Properties of Hydrated Lime

• Chemical formula: Ca(OH)₂
• Appearance: White to off-white powder
• Nature: Strongly alkaline (pH ~12.4 in solution)
• High neutralizing value — effective at raising pH in acidic effluents and soils
• Excellent chemical stability — long shelf life when stored correctly
• Low solubility in water, forming limewater/milk of lime when mixed
• Non-flammable and non-explosive under normal handling conditions

Grades & Chemical Composition

Shivi Minerals supplies hydrated lime across seven purity grades, from 70% to 94% Ca(OH)₂, so buyers can select the grade that matches their process requirement and budget rather than paying for purity they don't need.

Choosing a grade: high-purity 92–94% grades are typically specified for water treatment, food-grade clarification, and chemical manufacturing where precise dosing matters. Mid-range 80–90% grades suit most construction and general industrial neutralization work. 70–75% grades are commonly used in bulk soil treatment and lower-sensitivity applications where cost efficiency matters more than purity.

Industrial Applications of Hydrated Lime

Water & Wastewater Treatment

Hydrated lime is one of the most widely used chemicals in municipal and industrial water treatment. It corrects pH, softens hard water, and precipitates heavy metals and impurities out of effluent before discharge. Its high neutralizing value makes it effective even in acidic industrial wastewater streams.

Construction

Hydrated lime is a traditional ingredient in mortar, plaster, whitewash, and lime-based cement blends. It improves workability, water retention, and long-term durability of masonry work, and is still specified in heritage and eco-construction projects for its breathability compared to modern cement.

Steel Industry

Steel plants use hydrated lime as a flux and for flue gas desulfurization (FGD), where it reacts with sulfur dioxide in exhaust gases to reduce emissions. It's also used in slag conditioning during steel refining.

Sugar Industry

In sugar refining, hydrated lime is used to clarify raw juice extracted from sugarcane or sugar beet, precipitating impurities so they can be filtered out. This is a critical step in producing clear, high-quality sugar, and hydrated lime is recognized as a food-processing aid (E526) for this purpose.

Chemical Manufacturing

Hydrated lime is a raw material for producing calcium-based compounds such as calcium stearate, calcium hypochlorite (bleaching powder), and other calcium salts used across the chemicals industry.

Agriculture

Applied to soil, hydrated lime reduces acidity, raises pH, and supplies bioavailable calcium to crops — improving nutrient uptake and yield in acidic soils.

Paper & Pulp

Used in the causticizing process to recover and regenerate the chemicals used in pulping, hydrated lime helps paper mills reduce raw material costs and environmental impact.

Advantages of Shivi Minerals' Hydrated Lime

• Consistent purity across every batch, backed by in-house quality testing
• Multiple grades (70–94%) to match application-specific requirements without overpaying for unneeded purity
• Controlled particle size (BSS 100–400 mesh) for predictable reactivity and dissolution
• Large-scale manufacturing capacity (75,000 MT/annum) to support both trial orders and long-term bulk contracts
• Direct-from-manufacturer pricing — no intermediary markups
• Responsive logistics from our Rajasthan facility to destinations across India

Quality Assurance

Every batch of hydrated lime produced at our Khimsar facility is tested for Ca(OH)₂ content, moisture, magnesium oxide, acid-insoluble matter, and particle size before it is approved for dispatch. This batch-level testing is what allows us to guarantee the specification tolerances shown in the grade table above, rather than offering only indicative ranges.

If your project requires a specific certification (ISO, BIS, or a customer-specific quality protocol), contact our team — we can confirm current certification status and provide test certificates (TC/COA) with your shipment.

Packaging & Supply

• Minimum Order Quantity: 20 MT
• Indicative price range: ₹3,000 – ₹6,000 per MT (varies by grade and order volume — contact us for a current quote)
• Packaging options: 25 kg / 50 kg HDPE/PP bags, jumbo (bulk) bags on request, and bulk tanker dispatch for large-volume buyers
• Storage & handling: Store in a dry, moisture-free environment in sealed bags; hydrated lime absorbs moisture and CO₂ from air over time, which reduces reactivity. Handle with gloves, safety goggles, and a dust mask, as the powder is alkaline and can irritate skin, eyes, and airways.

Hydrated Lime vs. Quick Lime vs. Slaked Lime — What's the Difference?

These three terms are often confused. Here's the distinction:

In short: quicklime is the raw, high-heat-reactive form; hydrated lime is the stabilized, hydrated form produced from it. Most end-use industrial and construction applications call for hydrated lime specifically because of its easier handling and predictable reactivity.

Common Mistakes Buyers Make When Sourcing Hydrated Lime

1. Choosing the highest purity grade by default. Many applications (e.g., general soil treatment or bulk neutralization) don't need 94% purity — paying for it wastes budget better spent on volume.
2. Ignoring particle size (mesh). Reactivity depends heavily on mesh fineness, not purity alone. A coarser, lower-mesh product can underperform even at higher Ca(OH)₂ content.
3. Not checking moisture content. High moisture reduces effective reactivity and shortens shelf life — always check the moisture spec, not just purity.
4. Overlooking storage conditions before ordering. Hydrated lime degrades on exposure to air and moisture; buyers who don't have dry storage in place often see quality loss before the material is even used.
5. Sourcing without a test certificate. Always request a certificate of analysis (COA) with each batch to confirm the spec matches what was ordered.
6. Underestimating lead time for bulk orders. Large-volume or export orders need to be planned against production and packaging capacity — confirm lead times upfront.

Buying Guide: How to Choose the Right Hydrated Lime Grade

1. Identify your application — water treatment, construction, agriculture, food processing, or chemical manufacturing each has different tolerance for impurities.
2. Check required Ca(OH)₂ purity — match your process specification against our 70–94% grade table above.
3. Confirm particle size requirements — finer mesh (BSS 300–400) for fast-reacting applications like water treatment; coarser mesh acceptable for construction and soil use.
4. Decide on packaging — 25/50 kg bags for smaller or manual-handling operations; jumbo bags or bulk tanker for high-volume continuous processes.
5. Request a sample and COA before committing to a large order, especially for a new supplier relationship.
6. Confirm MOQ and pricing — Shivi Minerals' MOQ is 20 MT; contact us for current pricing by grade and volume.
