Zirconia Mixing Jar for Wet/Dry Milling (Dual-Use Grinding Vessel)

Zirconium Ball Mill Jar – Technical & Commercial Description

1. Material Composition

• Primary Material: Yttria-Stabilized Zirconia (YSZ) – Typically 3 mol% (3Y-ZrO₂) or 5 mol% (5Y-ZrO₂) Y₂O₃ for enhanced thermal/mechanical stability.

• Alternative Grades:

  • Magnesia-Partially Stabilized Zirconia (Mg-PSZ) – For extreme wear resistance.

  • Ceria-Stabilized Zirconia (Ce-ZrO₂) – Higher fracture toughness.

• Purity: ≥ 99.5% ZrO₂ (low Al₂O₃/SiO₂ impurities to prevent contamination).

2. Key Properties

• Hardness: 1,200–1,400 HV (harder than alumina, comparable to tungsten carbide).

• Density: ~6.05 g/cm³ (high mass for efficient grinding momentum).

• Fracture Toughness: 5–10 MPa·m¹/² (resists cracking under impact).

• Thermal Stability: Withstands -196°C to 1,000°C (cryogenic to high-temp milling).

• Chemical Inertness: Resistant to acids/alkalis (pH 1–14) and organic solvents.

3. Design Features

• Capacity Range: 50 mL to 10 L (lab-scale to production).

• Lid System:

  • PTFE-sealed (leak-proof for wet milling).

  • Clamp-lock or screw-on (prevents spillage at high RPM).

• Interior Finish: Mirror-polished (Ra ≤ 0.1 μm) to minimize adhesion.

• Optional:

  • RFID tags for usage tracking.

  • Cooling jackets for temperature control.

4. Applications

• Nanoparticle Synthesis: TiO₂, SiO₂, graphene.

• Battery Materials: Homogenizing Li-ion cathode powders (NMC, LFP).

• Pharmaceuticals: API size reduction (sterile milling).

• Ceramics: Grinding ZrO₂/Al₂O₃ precursors.

• Metallurgy: Mechanical alloying of Fe/Ni/Co powders.

5. Advantages vs. Alternatives

6. Operational Guidelines

• Max Speed: ≤ 800 RPM (planetary mills).

• Loading: ≤ 2/3 volume (30–50% media fill).

• Media Pairing: Use ZrO₂ balls (ϕ3–20 mm) for optimal efficiency.

• Cleaning: Ultrasonic wash with ethanol or HNO₃ (5%).

7. Compliance & Standards

• ISO 9001/13485 (pharma-grade options).

• RoHS/REACH compliant.

• FDA-approved for food/pharma applications.

8. Pricing Range

• Lab-scale (100 mL): $200–500

• Production (5 L): $1,500–3,000

Why Choose Zirconia Jars?

• Zero contamination for high-purity processes (e.g., semiconductors).

• 10x longer lifespan than steel/alumina, reducing TCO.

• Energy-efficient (high density transfers kinetic energy effectively).

Description:

A planetary mill jar is a specialized container used in planetary ball mills for grinding, mixing, and homogenizing materials. It operates on the principle of planetary motion, where the jar rotates around its own axis while simultaneously revolving around a central axis. This dual motion generates high-energy impacts and friction, enabling efficient particle size reduction and uniform mixing. Planetary mill jars are available in various materials such as stainless steel, nylon, polyurethane, tungsten carbide, ceramic (alumina, zirconia), PTFE, and agate, each suited for specific applications and material compatibility. They come in a range of capacities, from small 50ml jars for lab-scale research to larger jars for industrial use.

Notice:

*Material Compatibility: Ensure the jar material is compatible with the sample and grinding media to avoid contamination or damage.

*Loading Capacity: Do not exceed the recommended filling volume (typically 1/3 to 1/2 of the jar’s capacity) to ensure efficient grinding and avoid overloading.

*Grinding Media Selection: Use appropriate grinding media (e.g., steel, ceramic, or zirconia balls) based on the material being processed.

*Sealing Check: Always ensure the jar is properly sealed to prevent leaks or contamination during operation.

*Speed and Time Settings: Adjust the rotation speed and grinding time according to the material properties to avoid overheating or excessive wear.

Cleaning and Maintenance: Clean the jar thoroughly after each use to prevent cross-contamination. Inspect for wear or damage regularly.

*Safety Precautions: Wear protective gear when handling the jar, especially when dealing with hazardous materials.

*Avoid Overheating: Monitor the temperature during operation, especially for heat-sensitive materials, and use cooling intervals if necessary.

*Proper Installation: Ensure the jar is securely mounted on the planetary mill to prevent imbalance or accidents during operation. *Storage: Store the jar in a dry, clean environment to prevent corrosion or contamination when not in use.
