Product Overview


This compact automatic planetary ball mill represents an advanced benchtop solution engineered for high-energy grinding, fine pulverization, and homogeneous mixing of laboratory samples. Utilizing a combination of intense impact and friction forces, the equipment efficiently reduces soft, medium-hard, brittle, dry, or low-viscosity materials into fine suspensions or powders down to sub-micron dimensions.
Designed primarily for material science laboratories, R&D institutes, ceramic engineering facilities, and chemical synthesis units, this system accommodates demanding sample preparation protocols. Its four-station design enables simultaneous processing of multiple batches, accelerating experimental throughput while maintaining strict quality control and zero cross-contamination standards across diverse media types.
Built to perform under rigorous operational schedules, the unit features an IP65-rated housing, integrated acoustic insulation, and comprehensive electronic protection systems. Procurement teams and laboratory managers can rely on this equipment to deliver repeatable particle size distributions, operational safety, and continuous thermal stability during extended high-energy milling sequences.
Key Features
- High-Energy Planetary Motion Architecture: Superimposed rotational forces create intense Coriolis acceleration, delivering high-impact and shear energy to achieve final particle sizes between 0.1 µm and 20 µm efficiently.
- Four-Station Batch Configuration: Equipped to hold four individual 100 ml grinding jars for a total processing volume of up to 400 ml, supporting multi-sample high-throughput preparation or parallel parameter testing.
- Flexible Media & Material Options: Accepts interchangeable grinding jars and balls made from tungsten carbide, zirconia, agate, stainless steel, or MC nylon, preventing contamination and chemical incompatibility.
- Intelligent Programmable Control: Offers flexible operational profiles including continuous duty, intermittent grinding, timed sequences, and automatic forward/reverse rotation with speed regulation and power-off memory retention.
- Integrated Safety & Monitoring Suite: Built-in sensors monitor real-time temperature conditions with high-temperature cut-off protection, electronic jar locking, emergency stop, and overload safeguards to prevent improper operation.
- Dual Grinding Capability: Fully capable of both dry pulverization and wet liquid-dispersion milling, allowing precise control over particle coating, mechanochemical reactions, and slurry homogenizations.
- Versatile Jar Clamping Systems: Supports both electric and manual jar locking options, providing secure sealing during high-velocity operations up to 800 r/min.
- Acoustic & Thermal Management: Designed with internal soundproofing layers to reduce workplace noise alongside high-efficiency heat dissipation vents for extended continuous operational stability.
