Product Introduction
The Laboratory Roller Ball Mill MRX-QM-2 is a compact grinding and mixing machine designed for laboratory research, material development, teaching, testing, and small-batch production. Unlike large industrial grinding systems, this roller-driven laboratory mill provides a practical solution for preparing smaller quantities of materials while maintaining a controlled and repeatable grinding process. Its roller configuration allows grinding jars to rotate continuously, creating the mechanical action required for particle size reduction and material mixing.
The MRX-QM-2 is suitable for both dry grinding and wet grinding, giving laboratories greater flexibility when working with different material systems. The variable-speed drive allows the roller speed to be adjusted according to material characteristics, grinding requirements, and experimental conditions. Its compact structure also makes it suitable for laboratories where available floor space is limited.
Designed for convenient operation, the machine allows grinding jars to be replaced efficiently when different materials or processing conditions are required. With a maximum roller speed of approximately 570 rpm, an adjustable roller spacing of 140 mm, and a single-jar load capacity of up to 80 kg, the MRX-QM-2 provides a useful balance between laboratory-scale flexibility and small-batch processing capability.

Core Features
The MRX-QM-2 uses a roller-based grinding mechanism to provide stable mechanical motion for laboratory-scale material processing. The adjustable operating speed makes it possible to optimize the grinding conditions for different materials rather than relying on a fixed-speed process.
Its compact construction is particularly suitable for research laboratories, pilot preparation areas, university laboratories, and other environments where equipment footprint is an important consideration. The machine is designed for straightforward operation, allowing researchers to concentrate on process development rather than complicated equipment setup.
The roller spacing can be adjusted according to the selected grinding jar and operating requirements. This provides greater flexibility when different jar sizes or configurations are used during material experiments.
The grinding system supports both dry and wet processing. This feature enables laboratories to select a suitable preparation method according to the physical properties of the material and the intended downstream application.
The machine body adopts a compact geometric design that provides a clean and professional appearance while making the equipment practical for laboratory environments. Its construction is intended to provide stable operation during extended grinding and mixing processes.
Main Functions
The primary function of the MRX-QM-2 is laboratory-scale fine grinding. Materials can be processed in suitable grinding jars to achieve the required degree of particle size reduction for subsequent testing, formulation, characterization, or production trials.
The machine can also be used for material mixing. During roller rotation, the contents of the grinding jar are continuously moved, helping distribute different components throughout the batch. This makes the equipment useful for experimental formulations where grinding and mixing need to be performed within the same processing stage.
Another important function is small-batch material preparation. Researchers can use the equipment to evaluate grinding conditions, compare material formulations, and prepare samples before scaling a process to larger equipment.
The adjustable speed function also supports process optimization. Different materials can require different mechanical conditions, and variable-speed operation gives researchers greater control when establishing suitable experimental parameters.
Specific Application Scenarios
In battery and energy-material research, the MRX-QM-2 can be used for laboratory preparation and mixing of selected powder materials where controlled particle processing is required. It can support material development before subsequent electrode preparation, formulation, or characterization.
For ceramic research, the machine can assist with the preparation and homogenization of ceramic powders and experimental formulations. Its dry and wet grinding capability provides flexibility for different ceramic processing routes.
In chemical and materials laboratories, the roller ball mill can be used for experimental grinding, dispersion, and mixing of suitable materials. Researchers can adjust the operating speed to investigate the relationship between processing conditions and final material characteristics.
Universities and research institutions can use the MRX-QM-2 for laboratory demonstrations, material science experiments, sample preparation, and process-development studies. Its compact structure makes it practical for teaching laboratories and research spaces with limited equipment capacity.
For small-batch manufacturing and pilot preparation, the equipment can be used to evaluate grinding and mixing parameters before a larger production system is selected. This makes it useful as an intermediate processing tool between laboratory experiments and scale-up activities.
