Materials & Technology:
Engineered using nanostructured steel grain refinement, these balls achieve:
- ASTM Grain Size 14 certification (128,000 grains per sq mm)
- Verified by SGS—62 times finer than traditional ASTM 8 standards
Core Hardness:
Maintains a uniform 63 HRC hardness from surface to center, resulting in no internal soft spots, cracking, or deformation, even after years of continuous use.

⚙️ Key Product Advantages

🧱 Exceptional Longevity

Virina balls exhibit an annual wear rate of only 2mm. For example:
- A 90mm ball lasts up to 45 years, whereas traditional balls may start deforming within just 6 months.

⚡ Superior Efficiency

Optimized spherical design enables superior rolling and cascading motion in the mill.
Delivers consistent particle size distribution, enhancing grinding throughput and mill productivity.

🪨 Built for Durability

No need for frequent ball sorting or removal of rejects.
After 10 years, worn 70mm balls may still be repurposed for second chamber use (reduced to 50mm), while maintaining high performance.

💥 High Impact Toughness

Rated at 20 J/cm², ensuring maximum resistance to shattering or structural failure under pressure.

💸 Significant Cost & Operational Savings

Inbound Freight Savings:
Reduce shipping volume and cost by up to 90% over the product lifecycle due to reduced need for reorders.
Minimal Top-Off Requirement:
Only 2%–3% of the original charge weight required annually, dramatically lowering long-term procurement needs.
Energy Efficiency:
Mills using Virina media can save up to $125,000 annually in energy costs through more efficient grinding.
No Reject Disposal Costs:
Virina balls eliminate the need for ball sorting, reject handling, and return freight.
Extended Liner Life:
Enhanced metallurgy results in up to 400% longer mill liner lifespan, protecting infrastructure and minimizing downtime.

📊 Proven Performance: Real-World Validation

A side-by-side comparison was conducted at a Midwestern U.S. cement plant, where two identical 4,500 HP ball mill circuits (each at 100 TPH capacity) were tested:

Operating Temperature:
Virina-operated mills ran at 184°F, compared to 195°F with traditional media—saving over 400 MBTU annually.
Wear & Deformation:
After 5 years, Virina balls wore evenly from 90mm to 80mm with no deformation.
Traditional balls showed core softness (58 HRC vs. 63 HRC), requiring frequent sorting and early replacement.
Performance Consistency:
Virina’s uniform hardness maintained higher mill uptime and throughput, avoiding loss from inefficient media.

The Problem with

Conventional Steel

Traditional steel manufacturing relies on quenching and tempering processes to increase hardness—sacrificing ductility, weldability, and elasticity in the process.

These internal stresses lead to cracking at welds and often require additional material to meet strength demands, resulting in heavier, less efficient products.

Furthermore, applying heat in downstream processes weakens conventional steel, creating potential points of failure.

The Virina Solution

VIRINA Steel removes the compromises inherent in traditional steel:

No quenching or tempering required
Uniform grain structure and consistent properties along all axes
Superior elasticity, weldability, and tensile strength
Join integrity using matched formulation filler rods
Optional surface treatments without compromising core properties

Our steel enables consistent, reliable performance—especially critical in high-stress and safety-sensitive applications.
