3mm Grinding Ball, Zirconium Oxide (100 pieces)

3mm Grinding Ball, Zirconium Oxide (100 pieces)

The 3mm Zirconium Oxide Grinding Balls are designed for use with Fritsch Planetary Mills and are essential for efficient sample preparation. These grinding balls are placed into grinding bowls along with the material to be milled. The final particle size of the sample depends on the size and number of grinding balls used. Larger balls typically produce coarser results, while smaller balls yield finer particles. It is recommended to avoid mixing ball sizes in a single bowl to ensure uniform grinding performance.

Proper selection of ball size, material, and quantity is crucial for optimal results and should be tailored to the specific application. Using a higher number of balls can reduce grinding times and produce finer distributions, provided the bowl is not overfilled. Ideally, the total volume of balls and sample should not exceed two-thirds of the bowl's capacity, leaving one-third free for effective movement and grinding action.

For harder samples, it is advisable to select grinding balls and bowls made from materials that are harder than the sample itself. For example, tungsten carbide balls in steel bowls or zirconium oxide balls in corundum bowls are ideal combinations for processing exceptionally hard or abrasive materials. However, when using dissimilar materials, users should be mindful of the potential risk of cross-contamination.

The 3mm zirconium oxide balls feature a density of 5.7g/cm³, making them highly effective for fibrous or abrasive samples. Each pack includes 100 balls for added convenience, and they are compatible with a range of grinding bowl sizes, including 500ml, 250ml, and 80ml. Larger grinding balls (greater than 3mm) are sold individually to meet specific needs.
