A planetary ball mill with a 100ml stainless steel vacuum jar is a high-performance benchtop grinding device designed for processing materials down to the nano scale in a controlled, inert atmosphere. This combination is essential for grinding air-sensitive, easily oxidized, or moisture-reactive materials that would otherwise degrade in ambient air.
The system consists of two main components:
The Planetary Ball Mill Main Unit: Provides the high-speed rotational motion that generates immense grinding energy.
The 100ml Stainless Steel Vacuum Jar: A specialized grinding container that can be evacuated and filled with an inert gas like Argon or Nitrogen.

| Feature/Component | Description and Benefit |
|---|---|
| Planetary Disk & Jars | The main disk (sun wheel) rotates, while the jars (planets) rotate in the opposite direction on their own axes. This creates high-energy impact forces from the grinding balls, ideal for rapid size reduction and mechanical alloying. |
| 100ml Stainless Steel Jar | Material: 304 or 316L Stainless Steel, known for high mechanical strength, wear resistance, and low contamination for many applications. Capacity: Ideal for R&D and small-batch production (typically 1/3 to 1/2 filling for effective grinding). |
| Vacuum & Gas System | Vacuum Port: Allows a vacuum pump to be connected to evacuate the jar's internal atmosphere (typically down to <1 Pa). Gas Inlet Valve: After evacuation, this valve is used to purge the jar with an inert gas (e.g., N₂, Ar) to create a pure, oxygen-free and moisture-free environment. Safety Valve: Often includes a pressure relief valve for operator safety. |
| Lid Sealing System | Utilizes a robust silicone or fluoropolymer O-ring and a clamping mechanism (e.g., wing-nuts or a quick-lock system) to ensure an airtight seal under vacuum and during high-speed operation. |
| Control System | Digital controls for setting Grinding Time (from seconds to hours), Rotation Speed (RPM), and Cycle Direction (alternating rotation to prevent caking). |
Loading: The material to be ground and the grinding balls are placed inside the 100ml jar. The jar is sealed tightly.
Atmosphere Control: A vacuum pump is connected to the jar's port to remove all air and moisture. The jar is then filled with an inert gas. This purge cycle may be repeated 2-3 times to ensure atmospheric purity.
Grinding: The sealed jar is securely mounted onto the rotating planetary disk of the mill. The program (time, speed) is set and started.
Planetary Motion: As the disk turns, the jar spins on its own axis in the opposite direction. The grinding balls inside are subjected to strong Coriolis and centrifugal forces, impacting the material with high energy against the jar's walls.
Result: This action rapidly crushes, mixes, and homogenizes the powder, achieving particle sizes in the micrometer or even nanometer range, all within a protected environment.
This setup is critical in advanced material science and chemistry labs:
Solid-State Battery Research: Grinding air-sensitive materials like Lithium Metal Anodes, Sulfide-based Solid Electrolytes (e.g., Li₃PS₄), and high-capacity cathode materials without oxidation.
Metal Alloying: Mechanical alloying of metallic powders (e.g., Aluminum, Magnesium, Titanium alloys) that would otherwise oxidize and form undesirable phases.
Advanced Ceramics: Processing of non-oxide ceramics like Silicon Nitride (Si₃N₄) or Silicon Carbide (SiC) which can oxidize at high energies.
MOFs & Porous Materials: Synthesis and size reduction of Metal-Organic Frameworks that might be sensitive to moisture.
Nanocomposites: Creating homogeneous mixtures of a metal or ceramic matrix with nano-reinforcements (e.g., Carbon Nanotubes, Graphene).
Prevents Oxidation & Contamination: Essential for working with pure metals, sulfides, and other reactive compounds.
Eliminates Moisture: Prevents hydrolysis of moisture-sensitive materials.
Reduces Fire and Explosion Risks: Allows safe grinding of flammable or pyrophoric materials.
Enables Reproducible Research: Provides a controlled environment, ensuring experimental consistency.
