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 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.

This low temperature planetary ball mill combines high-speed planetary motion with refrigeration to grind heat-sensitive materials without thermal degradation. The equipment operates by rotating four grinding jars in a planetary motion while an air cooling unit maintains the chamber temperature between 5 and 15 degrees Celsius.
Required Equipment: Atomfair XQM-100 Low Temperature Planetary Ball Mill
- Install Grinding Jars
Install four grinding jars containing the sample and grinding balls onto the main disc of the planetary ball mill. - Set Cooling Temperature
Set the grinding chamber temperature to the desired value within the range of 5 to 15 degrees Celsius using the refrigeration controller. - Start Grinding Process
Start the motor to initiate planetary motion at the required rotation speed for the specified grinding duration.
How does the integrated air cooling system maintain the grinding chamber at 5–15°C without compromising the grinding efficiency for heat-sensitive materials like lithium battery cathodes?
The air cooling unit uses air-conditioning compression refrigeration to circulate cold air, rapidly removing heat generated during grinding. The system is designed to control chamber temperature within 5–15°C depending on ambient conditions, enabling efficient planetary ball milling without thermal degradation of materials such as lithium cobalt oxide or rare earth powders. The stepless speed regulation via a frequency converter allows adjustment of rotation speed (0–240 r/min for the XQM-100) to balance grinding intensity and temperature.
What are the feed particle size limitations for different material types when using the XQM-100?
For soil materials, the maximum feed particle size is ≤10 mm; for all other materials, including ceramics, battery powders, and rare earth compounds, the feed size must be ≤3 mm. This constraint ensures efficient grinding and prevents damage to the grinding jars or motor. The mill can achieve a discharge particle size as fine as 0.1 μm, depending on the material and grinding process.
What are the key installation and operational requirements for the XQM-100 planetary ball mill?
The XQM-100 requires an 11 kW motor power supply and a floor space of at least 1750×1140 mm, with an overall height of 1330 mm. The unit weighs 1300 kg, so a reinforced floor or support structure is recommended. The grinding jar loading must not exceed two-thirds of the jar volume (material plus grinding balls) to avoid overloading.
The Atomfair XQM-100 integrates an 11KW gear-driven planetary mill with an air-cooled refrigeration system to achieve controlled low-temperature grinding (5–15°C), enabling ultrafine comminution of heat-sensitive ceramics, lithium battery materials, and rare earth powders down to 0.1 μm. Its 100 L total jar capacity and 1300 kg footprint necessitate substantial laboratory infrastructure, while the 3 mm feed size limit (10 mm for soils) requires upstream size reduction for coarse feeds.
Positive
- Controlled low-temperature grinding environment: The integrated air cooling unit, based on compression refrigeration, maintains the grinding chamber at 5–15°C, preventing thermal degradation of heat-sensitive materials during high-speed planetary milling.
- Ultrafine particle size capability: The high-energy planetary motion achieves discharge particle sizes down to 0.1 μm, enabling nanoscale comminution for advanced ceramics, battery materials, and rare earth powders.
Trade-offs
- Large physical footprint and mass: The XQM-100 measures 1750×1140×1330 mm and weighs 1300 kg, requiring a dedicated floor area with reinforced load-bearing capacity and adequate access for installation.
- Restricted feed particle size: Maximum feed size is 3 mm for most materials (10 mm for soils), necessitating pre-crushing or coarse milling before processing in this planetary ball mill.
