15mm Grinding Ball, Zirconium Oxide

Zirconium Oxide Grinding Ball, 15mm

Optimize your milling process with our 15mm Zirconium Oxide Grinding Balls. Designed for use with Fritsch Planetary Mills, these high-density (5.7g/cm³) balls are ideal for achieving precise particle size reduction. They are particularly effective for processing fibrous and abrasive samples, offering excellent wear resistance and minimizing contamination.

Key Features & Benefits:

• Optimal for Fibrous & Abrasive Samples: Zirconium oxide's hardness and durability make it suitable for challenging materials.
• High Density (5.7g/cm³): Ensures efficient energy transfer during grinding, leading to finer and more uniform results.
• Low Contamination Risk: Provides a cleaner grinding environment compared to some metal alternatives.
• Precision Milling: The 15mm size contributes to a specific grinding action, allowing for controlled particle size.
• Versatile Compatibility: Suitable for 80ml, 250ml, and 500ml grinding bowls.

Understanding Grinding Ball Selection: The final sample size in a planetary mill is directly influenced by the size and quantity of the grinding balls. Generally, larger balls yield a coarser product, while smaller balls lead to finer results. For optimal performance, avoid mixing different ball sizes within the same grinding jar.

Best Practices for Grinding: Through user trials, you can best determine the ideal ball size and quantity for your specific application. Increasing the number of balls typically reduces grinding times and produces finer size distributions, up to an optimal loading point. However, ensure that the total volume of balls and sample does not exceed two-thirds of the bowl's capacity to allow for effective grinding action.

For enhanced efficiency, especially with exceptionally hard samples, it's recommended to use grinding bowls and balls made from materials harder than your sample. Zirconium oxide balls, for example, pair well with corundum bowls. While striving for optimal hardness, be mindful that using dissimilar materials may introduce a minimal risk of cross-contamination.

Availability: Balls with a diameter of 3mm or smaller are sold in packs of 100 pieces. All other sizes, including this 15mm Zirconium Oxide ball, are sold individually.

Please note: Classic Grinding Bowls or Premium Grinding Bowls are purchased separately.
