Product Overview


This high-energy micro horizontal planetary ball mill represents an advanced solution for laboratory-scale sample preparation, ultrafine pulverization, mechanochemical synthesis, and precision powder blending. Engineered with a multi-axial planetary motion drive, the unit subjects samples to superimposed high centrifugal forces, rotational impact, friction, and gravity. By utilizing a horizontal jar arrangement, this system prevents localized material settling at the bottom of the grinding vessels, facilitating continuous mass transfer, uniform kinetic energy dissipation, and particle size reduction down to the sub-micron level (0.1–20 µm).
Designed specifically for demanding materials research, the equipment excels in processing small, low-to-medium hardness, brittle sample charges under both dry and wet milling regimes. It serves as an essential tool in advanced technical ceramics, powder metallurgy, battery storage research, pharmaceutical formulation, and electronic material development. Whether performing soft milling for clay homogenizing or high-intensity mechanical alloying, this unit delivers exceptional batch-to-batch consistency across diverse chemical and physical material matrices.
Built to withstand rigorous continuous duty in R&D and quality control facilities, the machine features a heavy-duty European standard transmission mechanism housed within a fully isolated stainless steel grinding chamber. With built-in soundproofing, active thermal dissipation, real-time temperature monitoring, and comprehensive electronic protection protocols, this compact benchtop system guarantees dependable operational safety, minimal maintenance overhead, and long-term reliability under continuous operating conditions.
Key Features
- Horizontal Planetary Motion Dynamics: Synthesizes superimposed rotational, centrifugal, friction, and gravitational forces to maintain sample suspension in horizontal jars, preventing particle compaction and bottom accumulation during high-energy runs.
- High-Speed Ultrafine Grinding: Driven by a high-torque European standard drive system capable of jar rotation speeds up to 1000 r/min, reducing feed sizes from < 2 mm down to a fine 0.1–20 µm discharge range.
- Four-Station Simultaneous Processing: Houses four independent 100 ml grinding jar stations for a total processing volume of 400 ml, allowing simultaneous high-throughput screening or multi-parameter milling comparisons.
- Contamination-Free Media Compatibility: Accommodates a broad array of specialized jar and media materials—including Zirconia, Tungsten Carbide, Agate, Stainless Steel, and MC Nylon—ensuring zero cross-contamination for sensitive analytical processes.
- Programmable Operational Modes: Features continuous, intermittent, and automated forward/reverse rotation swapping, complete with digital cycle timing, step-less speed regulation, and non-volatile power failure memory.
- Integrated Thermal Management & Protection: Equipped with live temperature monitoring, automatic high-temperature shutoff, thermal overload safeguards, emergency stop functionality, and dangerous operation interlocks.
- Refined Ergonomic Design: Incorporates an illuminated visual flip-top lid, sound-insulating cabinet insulation, active forced-air heat dissipation, and an IP65 rated dust and liquid protection seal for clean laboratory integration.
