Product Introduction
The Planetary Ball Mill MRX-XQM-1 is a compact laboratory milling system designed for fine grinding, powder preparation, material mixing, and particle-size reduction during research and development. Its four-station configuration allows multiple materials or formulations to be processed within the same experimental cycle, making it an efficient solution for laboratories working with small quantities of advanced materials.
The machine uses planetary movement in which the grinding jars rotate around their own axes while simultaneously revolving around the central axis. This combined motion generates intensive mechanical action between the grinding media and the sample, supporting efficient size reduction and homogeneous mixing of suitable materials.
The MRX-XQM-1 supports continuously adjustable speed through a variable-frequency drive, allowing researchers to establish appropriate milling conditions for different material systems. The revolution speed can be adjusted within a range of 50–400 rpm, while the jar rotation speed can reach 100–800 rpm.
A programmable control system allows users to define forward rotation, reverse rotation, pauses, and repeated operating cycles. Timing parameters from 1 to 999 minutes can be configured for different stages, making the equipment suitable for experiments that require alternating milling directions, intermittent operation, or controlled processing intervals.
The grinding chamber can accommodate four jars with capacities of 100 mL, 250 mL, or 500 mL per jar, depending on the selected configuration. Different jar and grinding media materials, including stainless steel, alumina, zirconia, agate, and PTFE, can be selected according to material compatibility and experimental requirements.
For applications requiring reduced exposure to ambient air, vacuum-compatible grinding jars can be used to conduct milling under vacuum conditions. This provides additional flexibility for researchers working with materials that require controlled processing environments.
With its compact footprint, low center of gravity, stable structure, and integrated safety protection, the MRX-XQM-1 is designed for universities, research institutes, corporate laboratories, and material development facilities that require flexible small-batch milling and mixing capabilities.

Core Features
Four-Jar Planetary Milling Configuration
The MRX-XQM-1 is equipped with four grinding positions, allowing researchers to process up to four samples during one experimental run. This configuration improves laboratory throughput when comparing different materials, formulations, or milling parameters.
Combined Revolution and Rotation Motion
The planetary movement combines jar rotation with orbital revolution. This creates intensive relative movement between the grinding media and sample, supporting efficient grinding and mixing for suitable materials.
Wide Variable-Speed Range
The variable-frequency drive provides stepless speed adjustment. Researchers can select suitable operating conditions based on material hardness, target particle size, grinding media, and experimental objectives.
Programmable Forward and Reverse Operation
The control system can automatically alternate between forward and reverse rotation with programmable timing intervals. Users can also configure pauses between cycles for applications that require intermittent milling or thermal management.
Multiple Grinding Jar Options
Grinding jars are available in stainless steel, alumina, zirconia, agate, and PTFE configurations. This selection allows researchers to choose a suitable jar material according to chemical compatibility and contamination-control requirements.
Vacuum Grinding Capability
Compatible vacuum grinding jars can be selected for experiments requiring milling under reduced-pressure conditions. This option expands the machine's suitability for materials that should be processed with limited exposure to ambient air.
Fine Particle Processing
Under suitable material and process conditions, the system can achieve particle sizes down to approximately 0.1 μm, supporting fine powder preparation and advanced materials research.
Integrated Safety Protection
The machine incorporates an interlock safety switch that prevents operation when the protective cover is open. This helps reduce operational risks during high-speed planetary milling.
