250mL Grinding Bowl for Fritsch Planetary Mill, Agate

250mL Grinding Bowl for Fritsch Planetary Mill, Agate

This premium 250mL agate grinding bowl is designed for use with the Fritsch Premium Planetary Mill.

Key Features & Usage:

Premium Grinding Bowls are essential components for the Fritsch Premium Planetary Mill, containing the grinding balls and the material to be processed. This complete set includes one 250mL grinding bowl, a matching lid, and a seal ring to ensure a secure, loss-free grinding process.

Operational Requirements:

• Hardness: It is a fundamental principle of milling that the grinding bowl material must be harder than the sample being ground. This prevents contamination and ensures efficient size reduction.
• Balanced Load: The Fritsch Premium Planetary Mill operates with two grinding stations. To ensure stable and effective operation, the mill must be run with balanced loads. This means using two identical bowls (same size and material) with equivalent total mass in each.
• Counterweighting: If only one sample is being prepared, a second identical bowl must be used as a counterweight. This counterweight bowl should be filled with a substance like fine sand to match the total mass of the bowl containing the sample and grinding media.
• Grinding Balls: Grinding balls are crucial for the milling process and must be purchased separately.

Material Selection Guide:

The choice of bowl material is critical and depends on the characteristics of your sample:

• Agate (This Product): Ideal for processing soft to medium-hard samples. Its low contamination properties make it perfect for applications where purity is paramount.
• Zirconium Oxide: Best suited for fibrous and abrasive samples, offering high wear resistance.
• Hardened Stainless Steel: A versatile option suitable for hard, medium-hard, and brittle materials.
• Hardmetal Tungsten Carbide: The ultimate choice for very hard and highly abrasive samples, providing maximum durability and grinding efficiency.
