Product Overview
This high-energy laboratory sample preparation platform is designed for demanding powder processing, ultrafine grinding, and mechanical alloying applications. Featuring an advanced dual-motor system that enables independent regulation of planetary sun-wheel revolution and jar self-rotation speeds, this system achieves customized kinetic energy profiles tailored to complex material characteristics. By allowing users to continuously fine-tune the speed ratio between revolution and rotation, the equipment provides complete control over impact forces and shear dynamics, ensuring optimal grinding, dispersion, and mixing kinetics for both research and specialized pilot-scale development.
Engineered for high-rigor environments across material science, metallurgy, advanced ceramics, energy storage, and chemical synthesis, this unit processes brittle minerals, metallic powders, oxide ceramics, and organic compounds down to sub-micron scales. The system supports up to four 500 mL grinding jars simultaneously, providing robust throughput for multi-sample preparation or higher-volume batch processing. Its operational flexibility allows rapid adaptation from coarse crushing of raw feed stock to delicate, high-purity mechanochemical milling under dry or wet processing regimes.
Constructed with heavy-duty structural components and premium electrical drives, the equipment delivers unwavering performance under demanding operational conditions. Capable of developing an impressive total centrifugal acceleration of up to 136G, this system operates with minimal acoustic and mechanical vibration due to its high-mass housing and precision balance configuration. Laboratory personnel can rely on this unit for consistent, reproducible results, cycle after cycle, backed by robust safety interlocks and comprehensive parameter control.
Key Features
- Independent Dual-Speed Regulation: Equipped with separate drive motors for planetary revolution (0–400 RPM) and jar rotation (0–1600 RPM), allowing operators to adjust speed ratios independently to fine-tune impact forces and frictional shear for diverse material formulations.
- Extreme Centrifugal Acceleration: Delivers up to 136G of total centrifugal acceleration—combining 16G of revolution acceleration with 120G of rotation acceleration—to achieve rapid particle size reduction, mechanical alloying, and mechanochemical reactions in reduced processing times.
- Large Touchscreen Control Interface: Features a user-friendly programmable color touchscreen panel that enables precise setting of revolution speed, self-rotation speed, total runtime, directional reversal intervals, and multi-step automated milling profiles.
- Flexible High-Capacity Processing: Accommodates four 500 mL grinding jars for a total batch volume of up to 2.0 L, making it suitable for high-throughput laboratory workflows, multi-sample testing, and batch powder preparation.
- Sub-Micron Grinding Performance: Capable of reducing brittle feed sizes under 10 mm and general feed sizes under 3 mm down to an average particle size of less than 20 µm in dry milling, and under 1 µm in wet milling (reaching ultrafine limits as low as 0.1 µm depending on process settings and media selection).
- Broad Material Media Compatibility: Designed to interface seamlessly with a wide range of jar and media materials, including SS304 stainless steel for metals, alumina or nylon jars with zirconia media for contamination-free oxide processing, and specialized wear-resistant alloys.
- Robust Structural Vibration Control: Built with a solid 245 kg industrial chassis that absorbs dynamic inertial loads and dampens operational vibration during high-speed, high-acceleration grinding sequences.
- Enhanced Safety and Operational Interlocks: Integrates a heavy-duty protective enclosure lid with safety interlock sensors, preventing operation when open and protecting operators from moving assemblies and thermal build-up.
