Lime Milk

Product Details

What Is Lime Milk?

Lime Milk is a ready-to-use, milky-white suspension of calcium hydroxide (Ca(OH)₂) or slaked quicklime (CaO) in water, with solids content typically adjustable between 5 % and 20 % by weight. It features smooth dispersion (10–50 µm particles), a highly alkaline pH (12.0–12.5), and minimal visible sediment, making it ideal for precise, continuous dosing in industrial processes.

How Is Lime Milk Produced?

Raw Material: High purity quicklime (CaO ≥ 90 %) or pre-hydrated lime like Hydrated Lime.

Hydration: Controlled slaking in agitated tanks (CaO + H₂O → Ca(OH)₂) under monitored temperature and pH.

Screening: Passage through 200-mesh sieves removes grit and oversized particles.

Stabilization: Addition of food-grade xanthan gum or other dispersants prevents settling during storage and transport.

Core Advantages of Lime Milk

Immediate Reactivity: Pre-dispersed Ca(OH)₂ eliminates dissolution time.
Low Viscosity: Compatible with peristaltic, diaphragm, or centrifugal pumps.
Safe Handling: Dust-free formulation reduces respiratory hazards.
Stable Suspension: Dispersants ensure long-term uniformity without frequent mixing.
Custom Formulations: Tailor solids content, particle size, and additives to your process.

Applications of Lime Milk

1 Water Treatment

pH Correction: 0.5–2 kg/m³ dosage for municipal or industrial effluent.
Heavy Metal Removal: ≥ 90 % precipitation of Cu²⁺ and Zn²⁺ (EPA 40 CFR 423).

2 Construction

Soil Stabilization: 5–10 % addition boosts clay CBR by ~150 %.
Masonry Mortar: Improves workability and accelerates carbonation hardening.

3 Food Processing

Sugar Refining: Clarification via controlled pH adjustment (FDA 21 CFR 184.1205).
Nixtamalization: Traditional corn treatment for tortilla production.

4 Agriculture

Soil pH Balancing: Raises acidic soils from pH 4.5 to 6.5 at 1–2 tons/acre.
Livestock Sanitation: Disinfects barns and equipment safely.

5 Chemical Synthesis

Precipitant: Generates calcium salts (e.g., calcium carbonate, CaSO₄) for pharmaceuticals and specialty chemicals.

Quality Certifications

Drinking Water: NSF/ANSI 60 certified.
Food Safety: FDA GRAS and EU Regulation (EC) No 1333/2008 compliant.
Sustainability: Carbon Trust–approved low-carbon footprint production.

FAQs About Lime Milk

Q: How does Lime Milk differ from Lime Slurry?
A: Lime Milk has lower solids (5–20 % vs. 15–40 %) and finer particles compared to Lime Slurry, making it ideal for precision dosing.

Q: Can Lime Milk freeze during storage?
A: Yes—store above 5 °C and use insulated tanks in cold climates.

Q: Is Lime Milk safe for organic farming?
A: Yes—OMRI-listed variants available when derived from natural limestone.

Q: Can concentration be adjusted on site?
A: Yes—dilution or concentration stations allow rapid solids tuning.
