10mm Grinding Ball, Sintered Corundum

10mm Grinding Ball, Sintered Corundum

Grinding Balls are essential components for use with Fritsch Planetary Mills, designed to enhance the grinding and milling process. These balls are placed into grinding bowls along with the sample material to be ground, ensuring efficient size reduction. The final particle size achieved depends on the size and quantity of the grinding balls used. Larger balls typically produce coarser results, while smaller balls yield finer products. It is not recommended to mix ball sizes within the same grinding jar, as this can affect the uniformity of the results.

Choosing the Right Grinding Ball Size and Quantity

The proper selection of ball size and quantity depends on the application and is often determined through user trials. Generally, using a higher quantity of balls reduces grinding times and produces a finer particle size distribution. However, there is an optimal loading point that should not be exceeded. It’s recommended to fill the grinding bowl no more than two-thirds of its total volume, leaving one-third empty to allow for effective grinding action.

Material Compatibility

For best results, use grinding balls and bowls made from a material that is harder than the sample being processed. For extremely hard samples, tungsten carbide balls paired with steel bowls or zirconium oxide balls used with corundum bowls can significantly improve grinding efficiency. Keep in mind that when using materials with different compositions, there is a risk of cross-contamination, which should be considered during material selection.

Additional Recommendations

• Grinding balls with a diameter of 3mm or smaller are sold in packs of 100 pieces, while larger balls like the 10mm size are sold individually.
• Grinding bowls, whether Classic Grinding Bowls or Premium Grinding Bowls, are sold separately and should be selected based on the application and material requirements.
• It’s critical to follow the recommended operating guidelines to ensure optimal grinding results and maintain the longevity of the equipment.

Technical Specifications and Features:

• Density: 3.8 g/cm³
• Recommended Samples: Medium-hard or fibrous materials
