Product Description

Laboratory Ball Mill, Nano-scale Grinding Machine, High-speed Sample Preparation

This machine is a high-speed, planetary small horizontal ball mill designed for nano-scale grinding and precision sample preparation in a laboratory setting. It represents the pinnacle of high-energy ball milling technology for R&D, capable of reducing material particle sizes down to the colloidal and nano range (often < 1 µm) through a combination of centrifugal forces and controlled mechanical alloying.

Core Working Principle: The "Planetary" Motion

The term "planetary" is the key to its high-energy performance. The mill features grinding jars that are securely mounted on a rotating disk (the "sun wheel").

Revolution: The disk rotates around a central axis (the "sun").
Rotation: Simultaneously, each grinding jar rotates around its own axis (like a "planet").
Counter-Directional Movement: Critically, the jars' rotation is in the opposite direction to the disk's revolution.

This dual rotation generates powerful Coriolis forces, causing the grinding balls inside the jars to experience a series of high-energy impacts against the opposite wall. The powder sample is trapped and ground between these colliding balls, leading to extreme size reduction and mechanical activation.

Key Features & Capabilities

Nano-Scale Grinding Capability

The high-energy impacts from the planetary motion are sufficient to fracture crystallites and break particles down to the nanoscale.

Requirements for Nano-Scale Results:

Grinding Time: Longer milling times generally yield finer particles.
Speed: Higher rotational speeds (rpm) increase impact energy.
Ball Size & Material: Smaller, denser balls (e.g., Zirconia) are used for final nano-grinding, as they provide more impact points per unit volume.

High-Speed Sample Preparation

Efficiency: Sample preparation that could take hours in conventional equipment is completed in minutes.
Consistency: Programmable settings ensure every sample is prepared under identical conditions for reproducible results.

Small Horizontal Ball Mill Design

Compact: Benchtop design ideal for laboratory environments with limited space.
Batch Sizes: Processes small quantities from 0.1 mL to several liters, depending on model.
Horizontal Orientation: Optimal design for transmitting centrifugal forces to grinding jars.

Laboratory-Grade Precision and Safety

Programmable Controls: Precise setting of grinding time, rotational speed, and cycle patterns.
Safety Interlock: Machine only operates when protective cover is securely closed.
Vibration Dampening: Ensures stable, low-noise operation.
