Product Overview
This advanced planetary ball mill introduces a revolutionary 360° omnidirectional flip motion, combining planetary rotation with a full tumbling action. By enabling the grinding jars to move in three dimensions, it eliminates dead zones and ensures that every particle receives uniform impact and shear forces. The result is exceptionally homogeneous powder with narrow particle size distribution, solving the common challenges of sedimentation and material sticking to jar walls.
Designed for both R&D and small-scale production, this system excels in processing advanced materials such as battery powders, electronic ceramics, phosphors, catalysts, and nanomaterials. Its ability to achieve ultra‑fine grinding down to sub‑micron levels makes it an indispensable tool for laboratories where precision and reproducibility are critical. From mechanical alloying to sample preparation for analytical testing, the equipment delivers consistent outcomes across a wide spectrum of hard and soft materials.
Built with industrial‑grade precision gearing and a robust frame, this mill provides reliable long‑term operation even under continuous use. The intuitive PLC touchscreen controller offers programmable cycles with memory, while the brake‑locked flip motor enhances safety and convenience. Trust in its engineering to deliver the same high performance run after run, backed by a design that prioritizes durability and user safety.
Key Features
- 360° Omnidirectional Rotation: The planetary disk performs a full 360° flip while undergoing revolution, creating a three‑dimensional grinding motion that fully exposes every particle to impact and shear, resulting in unmatched uniformity and fast milling times.
- Precision Gear Drive: High‑grade special material gears are CNC‑machined to ensure meshing accuracy. This delivers smooth, low‑noise operation at high speeds and guarantees stable torque output, even under heavy loads.
- Intelligent PLC Control System: A user‑friendly microcomputer touchscreen allows programming of forward/reverse intervals, run time, and pause cycles. The memory function stores protocols for repeatable processing, reducing operator error and setup time.
- Brake‑Lock Flip Motor: The flip mechanism incorporates a brake motor that securely locks the planetary disk at any angle during loading or inspection, providing a safe working environment and convenient access to the jars.
- Versatile Jar Compatibility: The system accommodates grinding jars from 0.05 L to 25 L in a wide range of materials—stainless steel, zirconia, alumina, PTFE, and more—to meet diverse purity and contamination requirements.
- Robust Industrial Construction: All structural components are manufactured using CNC technology, with a focus on heavy‑duty durability. The enclosure features a professional industrial design that is both functional and aesthetically refined.
- Efficient Heat Dissipation: The design facilitates adequate airflow around the grinding chamber to minimize heat buildup during extended runs, protecting temperature‑sensitive samples and prolonging component life.
- Scalable Capacity Options: The series offers models ranging from benchtop units with a total volume of 0.4 L to large floor‑standing systems with 100 L capacity, ensuring a solution for every scale of operation from lab research to pilot production.
