Description
Low Temperature Planetary Ball Mill
Product Introduction
Low temperature planetary ball mill is a combined equipment of planetary ball mill and refrigeration device. During high-speed grinding, most materials will heat up due to friction or exothermic reactions, which may alter the physical and chemical properties of materials and produce negative grinding effects. Low temperature planetary ball mill is mainly used for material grinding processes requiring strict temperature control.
Operating Principle of Planetary Ball Mill
Four grinding jars are installed on the main disc of the planetary ball mill. When the motor drives the main disc to rotate, the grinding jars revolve around the main disc axis and rotate simultaneously driven by the planetary mechanism, performing planetary motion. The grinding balls inside the jars rub and collide with each other under high-speed planetary motion, enabling efficient sample grinding and mixing.
Product Application

Product Features
Low temperature planetary ball mill is a combined equipment of planetary ball mill and air cooling device. The air cooling unit adopts the air-conditioning compression refrigeration principle, and the cold air circulation quickly removes heat generated during grinding. According to ambient temperature differences, the temperature of the grinding chamber can be controlled at 5–15℃. It is mainly used for ultra-fine grinding of materials under low-temperature processes. The air cooling device features simple structure, convenient operation, easy maintenance and low energy consumption.

Operate this ball mill with the integrated air cooling unit activated to prevent thermal degradation of heat-sensitive materials. Ensure all grinding jars are properly seated and locked before initiating planetary motion to avoid mechanical hazards.
- Cooling Unit Activation: Activate the air cooling unit before starting the motor to maintain chamber temperature between 5°C and 15°C.
- Jar Securement: Securely fasten each grinding jar onto the main disc using the locking mechanism to prevent displacement during rotation.
- Material Compatibility: Avoid grinding materials that undergo vigorous exothermic reactions, as the cooling capacity may be insufficient to control temperature rise.
This process ensures safe and effective grinding of heat-sensitive materials while maintaining the required low temperature. Follow these steps after installing the machine and connecting power.
Required Equipment: Planetary ball mill with air cooling unit, Grinding jars (4), Grinding balls
- Install jars
Install four grinding jars onto the main disc and lock them securely into place. - Add material and balls
Add the material to be ground and an appropriate number of grinding balls into each jar, then seal the lids. - Set rotation speed
Set the rotation speed to the desired value between 0 and 580 r/min using the control panel. - Activate cooling
Turn on the air cooling unit and allow the chamber to reach the target temperature of 5–15°C. - Start grinding
Start the motor to begin the planetary grinding process and monitor the temperature continuously. - Unload jars
After the grinding cycle completes, stop the motor, wait for jars to stop moving, and carefully remove the jars for unloading.
How does the air cooling system's 5–15°C grinding chamber range affect milling efficiency for heat-sensitive materials versus ambient temperature grinding?
The air cooling system maintains a grinding chamber temperature of 5–15°C, which suppresses thermal decomposition or phase changes in heat-sensitive materials without reducing the mill's maximum rotational speed of 580 r/min. This controlled low-temperature environment allows the XQM-(8-12) to achieve discharge particle sizes down to 0.1 μm while preserving material integrity, whereas ambient temperature grinding would risk altering physical and chemical properties due to friction or exothermic reaction heat.
What grinding jar sizes and configurations are compatible with the XQM-(8-12) for processing lithium cobalt oxide or similar cathode materials?
The XQM-(8-12) accepts grinding jars with a holder inner diameter of 162 mm and a jar volume range of 5–50 L per jar, supporting two or four jars operating simultaneously for total volumes up to 200 L. For lithium cobalt oxide and other cathode powders, the jar revolution diameter of 275 mm and gear drive transmission provide the planetary motion needed for homogeneous grinding, with a feed particle size of ≤3 mm required for non-soil materials.
What electrical and spatial infrastructure is required to install and operate the XQM-(8-12) low-temperature planetary ball mill?
The XQM-(8-12) requires a 1.5 kW motor with stepless speed regulation via a brand frequency converter and occupies a footprint of 900×600×640 mm with a net weight of 168 kg. The integrated air cooling unit, which uses air-conditioning compression refrigeration, needs adequate ventilation for heat exchange and a stable power supply matching the motor rating; no additional water or liquid nitrogen lines are necessary.
The Atomfair XQM-(8-12) high-capacity low-temperature ball mill integrates an air-cooled refrigeration system to maintain grinding chamber temperatures between 5–15°C, enabling ultra-fine milling of heat-sensitive materials such as battery cathodes and advanced ceramics. Its high jar volume capacity supports production-scale synthesis while gear drive and frequency converter ensure precise speed control.
Positive
- Controlled low-temperature grinding: Integrated air cooling system maintains grinding chamber at 5–15°C, preventing thermal degradation of heat-sensitive materials during high-speed planetary ball milling.
- High capacity for production-scale milling: With up to 50L per jar and total system volume up to 200L, the XQM-(8-12) supports large batch processing suitable for pilot or production-scale material synthesis.
Trade-offs
- Infrastructure requirement for air cooling: The system requires a dedicated air-conditioning compression refrigeration unit and proper ventilation, adding to lab infrastructure and energy costs.
- Feed particle size limitations: Input material must be ≤10mm for soil and ≤3mm for other materials, necessitating pre-crushing for larger feedstocks.
