Product Description

25kg NETZSCH White Alumina Grinding Balls Media 1mm-50mm

Specialized alumina grinding balls designed for pigment processing and other high-precision grinding applications, ensuring color-free contamination in coatings and paints.

Key Features and Benefits

High-purity alumina composition for contamination-free grinding
Exceptional wear resistance and hardness (Mohs 9)
Chemical inertness suitable for pH 1-14 environments
Thermal stability up to 1,600°C
Available in precise sizes from 1mm to 50mm

Chemical Composition

Composition	Al2O3	SIO2	CaO+MgO	Fe2O3
Wt%	≥92	7 max	≤2	＜0.1

Typical Properties

Specific Gravity (g/cm³)	Bulk Density (kg/L)	Hardness (Moh's)	Water Absorption %	Self Wearing Loss % (24hrs)	Compression (Mpa)
≥3.65	≥2.2	9	＜0.01	≤0.012	≥2000

Available Sizes (Φ mm)

0.5-1.0	6.0	20.0	70.0
1.0	8.0	25.0	80.0
2.0	10.0	30.0	90.0
3.0	13.0	40.0	100.0
4.0	15.0	50.0
5.0	18.0	60.0

Performance Comparison

Mechanical & Physical Properties

Property	Alumina (92%)	Alumina (99%)	Zirconia	Steel	Silica Sand
Density (g/cm³)	3.6	3.9	6.0	7.8	2.2
Hardness (Mohs/HV)	9 (~1,500 HV)	9 (~1,800 HV)	8.5	6-7	7
Wear Rate (g/ton)	10-50	5-20	1-5	100+	300+
Compressive Strength	2,000 MPa	2,500 MPa	2,200 MPa	500 MPa	Low

Key Takeaways:

99% Alumina offers 30% lower wear than 92% grade
2-5x longer lifespan vs. steel in abrasive slurries
Harder than zirconia but less tough (ideal for fine grinding)

Chemical & Thermal Resistance

Property	Alumina (99%)	Performance Impact
Chemical Inertness	Resists pH 1-14	Safe for acids/alkalis, pharmaceuticals
Max Temperature	1,600°C	Stable in kilns, calcination
Thermal Shock	Moderate	Avoid rapid quenching (>200°C/min)
Contamination Risk	None	Zero metal ions (critical for Li-ion batteries)

Industry-Specific Performance

Industry	Benefit of Alumina Balls
Mining	50% lower replacement cost vs. steel in ore grinding
Pharma	FDA-compliant, no endotoxin release
Batteries	Prevents Fe/Ni contamination in cathode materials
Paints	Maintains color purity (no metal leaching)
