Laboratory desktop planetary ball mill 0.4L small nano-scale high-energy ball mill

This is a critical specification that defines the machine's scale and throughput.

What it means: The "0.4L" (400 ml) typically refers to the total combined volume of all grinding jars when the mill is fully loaded.

Common Configuration: This is most often achieved with four 100ml jars, or sometimes two 200ml jars. This makes it ideal for a small to medium-sized research lab.

Implication: It allows a researcher to process multiple samples simultaneously under identical conditions, which is essential for experimental consistency, parameter optimization, and improving lab efficiency.

This is the key performance descriptor that enables nano-scale results.

Source of Energy: The "high energy" comes from the planetary motion's high rotational speeds (often ranging from 800 to 1500 RPM). This generates immense centrifugal forces, causing the grinding balls to impact the sample with tremendous energy.

Why it matters: Standard ball mills use a tumbling action that is good for coarse grinding. To fracture particles down to the nanometer level, much more intense impact and shear forces are required. The "high-energy" nature of this planetary mill is what makes nano-grinding possible.

Outcome: Faster grinding times and the ability to process very hard, brittle, or tough materials.

This is the primary capability and application of the mill.

Goal: To reduce particle sizes to the nanometer range (1 - 100 nanometers).

Requirements: Achieving this requires the combination of:

• High Energy (as described above).
• Appropriate Grinding Media: Small, hard grinding balls (e.g., 0.1-3mm Zirconia) are used to create a high number of impact points.
• Precise Control: Digital control over time and speed to ensure reproducible results.
• Suitable Jar Material: Hard, contamination-resistant materials like Yttria-stabilized Zirconia or Agate.

These terms define the physical context of the machine.

Desktop: It is a benchtop instrument with a compact footprint, designed to fit easily in a lab without requiring special installation.

Small: This reinforces its use for R&D and small-batch processing, not for industrial-scale production. Sample sizes per jar can range from a few grams to about 50-100 grams, depending on jar size and material density.
