Planetary Ball Mill With 100ml Stainless Steel Vacuum Jar High-performance Benchtop Grinding Device

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.

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.
