Product Overview:
These are high-performance, customized zirconia grinding jars designed specifically for use in planetary ball mills, such as those manufactured by Guangzhou Zoli. They serve as the primary grinding containers where sample materials and grinding balls are placed for size reduction, mixing, homogenization, and mechanical alloying.
The key value proposition is that these are not generic jars; they are precision-engineered to ensure perfect compatibility, optimal performance, and long service life in planetary ball mill systems.
1. Key Features & Advantages
Perfect Compatibility:
Designed and machined to precisely fit the grinding jar platforms of Guangzhou Zoli planetary ball mills and other major brands. This includes custom fittings for secure locking and alignment.
Superior Material - Yttria-Stabilized Zirconia (YSZ):
Extreme Wear Resistance: Harder than alumina, leading to drastically reduced jar wear and minimal contamination. This extends the jar's lifespan and protects your samples.
Contamination-Free Grinding: Chemically inert and non-metallic. Ideal for grinding high-purity materials, advanced battery powders, pharmaceuticals, and ceramics where even trace metal or chemical contamination is unacceptable.
High Density & Strength: The dense, fine-grained structure resists impact from grinding balls, withstands the high mechanical forces of planetary motion, and is easy to clean.
Customization for Laboratory Needs:
Volume: Available in standard planetary mill volumes (e.g., 50ml, 100ml, 250ml, 500ml, 1L) and custom sizes.
Lid System: Customized lids with secure sealing mechanisms (e.g., rubber O-rings, silicone gaskets) to prevent leakage. Options for lids with safety valves or ports for atmosphere control (e.g., vacuum or inert gas purging) can be provided.
Configuration: Offered as single jars or in matched sets to ensure balanced loading in the planetary mill, which is critical for smooth operation and preventing machine damage.
2. Compatibility with Guangzhou Zoli Planetary Ball Mills
Seamless Integration: These jars are designed to be direct replacements or premium upgrades for the original jars supplied with Zoli mills. They match the socket design and clamping mechanism perfectly.
Optimized Performance: Using a jar with the correct dimensions and weight is crucial for the dynamic balance of a planetary mill. These customized jars are engineered to maintain this balance, ensuring the mill operates efficiently, quietly, and without excessive vibration.
Enhanced Experiment Quality: By providing a contamination-free and highly durable grinding environment, these zirconia jars help researchers and technicians using Zoli mills achieve more consistent, reliable, and pure grinding results.
3. Applications in the Laboratory
These jars are essential for any application requiring fine grinding and mixing in a planetary ball mill, including:
Battery Material Research: Synthesis and grinding of cathode/anode materials (e.g., LFP, NMC) for lithium-ion batteries.
Geology & Mineralogy: Pulverizing rock and soil samples for XRF or XRD analysis.
Pharmaceuticals: Size reduction of active pharmaceutical ingredients (APIs) and homogenization of formulations.
Ceramics & Powder Metallurgy: Preparing nano-powders, mechanical alloying, and mixing ceramic compositions.
Electronics: Grinding of functional materials like ferrites, dielectrics, and semiconductors.
4. The "Precision Ceramic Processing" Behind the Jars
The ability to offer customized, high-performance jars relies on advanced manufacturing:
Advanced Forming: Using isostatic pressing to create a uniform, high-density "green" body of the jar.
CNC Machining (Green State): Before sintering, the jar is pre-machined to create precise threads for the lid, specific grooves for O-rings, and the exact outer geometry for a perfect fit in the mill's socket.
High-Temperature Sintering: Fired at over 1500°C to achieve full densification and the final zirconia ceramic properties.
Precision Finishing: The sealing surfaces and critical dimensions are precision-ground and polished to ensure a perfect seal and flawless operation.
