15mm Grinding Ball, Sintered Corundum

15mm Grinding Ball, Sintered Corundum

Grinding Balls are essential components for use with Fritsch Planetary Mills. These balls, placed into grinding bowls along with the sample, facilitate efficient milling and determine the final particle size of the sample. The size and quantity of the grinding balls directly influence the milling outcome—larger balls tend to produce a coarser product, while smaller balls yield finer results. To ensure optimal performance, it is not recommended to mix balls of different sizes in the same grinding bowl.

Optimal Usage Guidelines:

• Selecting the appropriate ball size and quantity is critical for achieving the desired results. This is often best determined through user trials.
• Using a larger number of balls can reduce grinding times and improve size uniformity, but overloading the bowl (beyond two-thirds of its volume) can hinder performance. Reserve one-third of the bowl’s volume for effective grinding action.
• For best results, choose grinding bowls and balls made of a material harder than the sample being processed. For exceptionally hard samples, tungsten carbide balls in steel bowls or zirconium oxide balls in corundum bowls offer enhanced grinding efficiency while minimizing wear.
• Be aware of potential cross-contamination when using dissimilar materials in the grinding process.

Material and Compatibility:

• The 15mm sintered corundum grinding ball features a density of 3.8 g/cm³, making it ideal for medium-hard, fibrous samples.
• Compatible with a range of grinding bowl sizes, including 500mL, 250mL, and 80mL.
• Grinding bowls and balls should be purchased separately, with options for Classic Grinding Bowls or Premium Grinding Bowls available.

Additional Information:

• Grinding balls with a 3mm diameter or smaller are sold in packs of 100, while larger balls, including the 15mm size, are sold individually.
• The high-quality sintered corundum construction ensures durability and reliable performance during extended use.

Applications: The 15mm Grinding Ball, Sintered Corundum, is suitable for a wide range of applications, including:

• Sample preparation for chemical analysis
• Powder mixing for research and development
• Milling of medium-hard to fibrous materials in fields such as pharmaceuticals, materials science, geology, and environmental testing.

Ensure your milling process is efficient, precise, and tailored to your specific needs with the right grinding balls and bowls. For more details on compatibility or assistance with product selection, feel free to contact our team of experts.
