Product Introduction
The Planetary Ball Mill MRX-XQM-1 is a compact laboratory grinding system developed for researchers who need controlled and repeatable processing of powders, particulate materials, and experimental material formulations. Rather than relying on simple rotational grinding, its planetary motion creates combined centrifugal and impact forces inside the grinding jars, allowing materials to undergo intensive size reduction, mixing, and dispersion within a relatively small laboratory footprint.
The four-station configuration enables up to four grinding jars to operate during one experimental cycle. Researchers can therefore compare different materials, grinding media, formulations, or process parameters without requiring separate runs for every sample. This makes the MRX-XQM-1 particularly useful for material screening, formulation development, and comparative laboratory studies.
A variable-frequency drive allows the grinding speed to be adjusted according to the characteristics of the material and the desired processing result. The control system also supports programmed forward and reverse operation, continuous operation, timed operation, and alternating rotation sequences. Such flexibility allows researchers to build different grinding procedures for brittle powders, ceramic materials, battery-related materials, and other laboratory samples.
The machine supports grinding jars made from stainless steel, alumina, zirconia, agate, PTFE, and other materials. The selection of jar and grinding media can therefore be matched to the chemical characteristics and contamination requirements of different experiments. Vacuum grinding jars can also be configured when processing requires a reduced-pressure environment.
With a compact structure, low center of gravity, safety interlock, and programmable operating functions, the MRX-XQM-1 is designed for practical laboratory use. It can serve research teams working on Battery Materials, ceramics, minerals, metallurgy, electronics, chemical formulations, advanced materials, and other fields requiring controlled powder preparation.

Core Features
Four-Jar Parallel Processing
The four-station configuration allows researchers to process multiple samples in parallel. Different materials or process conditions can be evaluated during the same operating cycle, improving laboratory testing efficiency.
Combined Planetary Motion
Each grinding jar experiences both revolution and rotation. The combined movement generates repeated impact and friction between the grinding media and material, supporting intensive laboratory-scale milling and mixing.
Variable-Frequency Speed Control
The variable-frequency control system provides flexible speed adjustment, allowing researchers to select a suitable operating condition instead of relying on a fixed grinding speed.
Programmable Forward and Reverse Operation
Forward, reverse, pause, continuous, and alternating sequences can be programmed according to the experimental process. This is useful when a material requires intermittent grinding or periodic changes in movement direction.
Multiple Grinding Jar Materials
A selection of grinding jar and media materials allows the equipment configuration to be adapted to different sample characteristics, hardness levels, chemical environments, and contamination requirements.
Vacuum Grinding Capability
Vacuum-compatible grinding jars can be selected for applications where the material needs to be processed under reduced pressure or where exposure to the surrounding atmosphere needs to be limited.
Integrated Safety Interlock
A safety switch is incorporated into the machine to prevent operation when the protective cover is open. This provides an additional layer of protection during laboratory operation.
Compact Laboratory Configuration
The low-center-of-gravity structure and compact footprint make the MRX-XQM-1 suitable for laboratories where controlled powder processing capability is required without installing a large industrial mill.
Main Functions
Fine Grinding
The MRX-XQM-1 provides intensive mechanical grinding for reducing suitable feed materials into fine particulate forms. Under appropriate material and process conditions, the specified output particle size can reach approximately 0.1 μm.
Powder Mixing
The planetary movement promotes repeated movement of the material and grinding media, allowing the machine to be used for laboratory-scale blending of compatible powders and particulate formulations.
Material Dispersion
The high-energy movement inside the grinding jars can assist in dispersing fine particles and agglomerates, making the machine useful for selected advanced-material and nanomaterial research applications.
Experimental Sample Preparation
The four-jar configuration enables researchers to prepare multiple experimental samples simultaneously, supporting comparative material studies and process optimization.
Controlled Grinding Process Development
Adjustable speed, programmable running sequences, and selectable grinding jars allow researchers to modify key process variables during material development and laboratory-scale process validation.
