Product Introduction
The MRX-XJB-4 Small Planetary Vacuum Mixer is designed for laboratory-scale material preparation where mixing uniformity, air removal, and process control are essential. The system combines planetary mixing with an integrated vacuum environment, allowing materials to be processed while reducing air incorporation during mixing.
For lithium-ion battery research, the mixer is particularly suitable for preparing cathode and anode slurries before electrode coating. The planetary mixing mechanism is designed to handle relatively viscous formulations while maintaining effective material circulation throughout the mixing vessel.
The vacuum-assisted process helps reduce air trapped within the material during preparation. This is valuable when researchers need a more homogeneous slurry for subsequent electrode processing and laboratory cell fabrication.
Beyond battery research, the MRX-XJB-4 can also be used for powder-based formulations, ceramic materials, and other laboratory materials requiring controlled high-viscosity mixing. Its compact design makes it suitable for research laboratories where equipment footprint and process flexibility are important considerations.
With a maximum mixing speed of 1,400 rpm, programmable three-stage operation, and an integrated vacuum pump capable of reaching approximately -0.08 MPa, the MRX-XJB-4 provides researchers with greater control over laboratory mixing procedures.

Core Features
Dual-Shaft Planetary Mixing
The MRX-XJB-4 uses a dual-shaft planetary mixing configuration designed to improve material circulation within the vessel. This structure is particularly useful for laboratory formulations where conventional single-axis mixing may not provide sufficient movement through higher-viscosity materials.
Vacuum-Assisted Mixing
An integrated vacuum system allows the mixing process to take place under reduced pressure. Removing air during mixing can help minimize bubbles incorporated into the slurry and improve the consistency of the prepared material.
High-Speed Mixing for Viscous Materials
With a maximum speed of 1,400 rpm, the mixer provides sufficient rotational capability for laboratory formulations with relatively high viscosity. The planetary movement helps distribute the material throughout the mixing vessel during processing.
Programmable Three-Stage Operation
The MRX-XJB-4 supports three programmable mixing stages. Researchers can set different speeds and operating times for individual stages, allowing multi-step mixing procedures to be adapted to specific material formulations.
Flexible Mixing Vessel Configuration
The standard system supports a 150–500 mL stainless steel vacuum mixing vessel. Other vessel configurations can be accommodated according to the required container volume and mixing application.
Compact Laboratory Footprint
Measuring only 330 × 300 × 480 mm, the MRX-XJB-4 is designed for laboratory environments where bench and floor space may be limited. Its compact structure allows it to be incorporated into battery research and material preparation workflows without requiring a large equipment area.
Integrated Vacuum System
The built-in vacuum pump eliminates the need for a separate external vacuum source in the standard configuration. The system can reach approximately -0.08 MPa, providing controlled vacuum conditions during material mixing.
Main Functions
Battery Electrode Slurry Preparation
The primary application of the MRX-XJB-4 is the preparation of cathode and anode slurries used in lithium-ion battery research. The combination of planetary mixing and vacuum processing helps researchers obtain a more consistent material formulation before electrode coating.
Material Homogenization
The planetary mixing motion promotes continuous material movement within the vessel, supporting uniform distribution of powders, binders, solvents, and other formulation components.
Air Removal During Mixing
Vacuum processing reduces the amount of air retained in the material during mixing. This is particularly useful for formulations where entrapped bubbles could negatively affect subsequent processing.
High-Viscosity Material Mixing
The dual-shaft planetary structure is suitable for laboratory formulations that require stronger mixing action than conventional low-speed laboratory stirrers can provide.
Multi-Stage Mixing Processes
Researchers can create sequential mixing programs using different rotational speeds and durations. This allows the same equipment to support different material preparation procedures without manually changing the process between every stage.
Ceramic and Powder Material Processing
In addition to Battery Materials, the mixer can be applied to selected ceramic formulations and powder-based materials that require controlled laboratory-scale mixing under vacuum.
Specific Application Scenarios
Lithium-Ion Battery Research Laboratories
The MRX-XJB-4 can be integrated into lithium-ion battery laboratory workflows for preparing cathode and anode slurries before electrode coating. It can serve as the mixing stage between raw material preparation and electrode fabrication.
Battery Electrode Development
Researchers developing new electrode formulations can use the mixer to prepare small batches of material under controlled speed, time, and vacuum conditions. This is particularly suitable for experimental work where formulation quantities are limited.
New Battery Material Evaluation
When laboratories compare different active materials, binders, conductive additives, or formulation ratios, a small-capacity vacuum mixer can help prepare experimental batches without requiring large-scale production equipment.
Solid-State Battery Research
For selected solid-state battery material formulations, controlled laboratory mixing can be an important step before electrode or cell preparation. The MRX-XJB-4 can be incorporated into appropriate material preparation workflows where its vacuum mixing capability matches the formulation requirements.
Ceramic Material Research
The planetary mixing structure can also support laboratory preparation of ceramic formulations and other powder-based materials that require intensive and homogeneous mixing.
University and Research Institute Laboratories
The compact dimensions and relatively small vessel capacity make the MRX-XJB-4 suitable for university laboratories, research institutes, battery technology centers, and other R&D environments working with small material batches.
Battery Pilot-Line Development
The MRX-XJB-4 can also serve as a laboratory mixing unit during early-stage process development before a battery research project advances toward larger-scale slurry preparation and pilot production.
