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.

Working Principle
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.

This device requires a stable, grounded electrical supply and operation within a temperature-controlled environment to prevent motor or refrigeration unit overload. The grinding chamber temperature must be maintained between 5–15°C to mitigate material degradation risks from friction-induced heat.
- Electrical Safety Limit: Ensure the mill is connected to a properly grounded outlet with a rated capacity matching the motor power specification to prevent electrical hazards.
- Mechanical Containment Requirement: All grinding jars must be securely sealed before operation to contain materials and grinding balls during high-speed planetary motion.
- Material Degradation Risk: Continuously monitor the grinding chamber temperature to avoid exothermic reactions or thermal alteration of heat-sensitive materials.
- Cooling System Constraint: The air cooling unit must be free of obstructions and operating correctly before initiating any grinding process to maintain the 5–15°C range.
Inspect all components and verify the cooling system is functional before loading materials. Follow these steps to initialize and run the mill while maintaining temperature control.
Required Equipment: Low Temperature Planetary Ball Mill
- Inspect Equipment
Inspect grinding jars, balls, and seals for cracks or wear, and confirm the air cooling unit is connected and free of debris. - Load Material
Transfer the material and appropriate grinding balls into the jars, then seal each jar tightly with its lid. - Set Parameters
Set the desired rotation speed and cooling temperature on the control panel according to the material properties and processing requirements. - Start Cooling
Start the air cooling unit and allow the chamber to reach the target temperature before beginning the grinding cycle. - Initiate Grinding
Start the mill motor and observe the rotation for the first minute to confirm smooth operation and no unusual vibration. - Monitor Process
Monitor the temperature display continuously and adjust parameters if the chamber temperature exceeds the safe 15°C limit. - Shut Down Safely
Stop the mill motor first, then turn off the cooling unit, and allow the jars to cool before opening to prevent thermal shock.
How does the XQM-0.4's lower maximum speed of 870 r/min affect its ability to grind hard ceramics to sub-micron particle sizes compared to faster models like the XQM-0.2?
The XQM-0.4 operates at a maximum rotation speed of 870 r/min, lower than the XQM-0.2's 1160 r/min, but it compensates with a larger jar revolution diameter of Φ140 mm and a 250W motor gear drive, enabling discharge particle sizes down to 0.1 μm for materials such as alumina and zirconia ceramics. The trade-off is reduced maximum speed for higher torque and capacity, which still achieves ultra-fine grinding due to the increased impact energy from the larger planetary diameter.
What grinding jar size and loading constraints apply when using the XQM-0.4's half-round jar holder with an 80 mm inner diameter for low-temperature operation?
The XQM-0.4A jar holder has an inner diameter of 80 mm, compatible with grinding jars whose outer diameter fits this dimension; the maximum loading capacity for material plus grinding balls is two-thirds of the jar volume. The product description does not specify jar materials, but typical jars for planetary ball mills include agate, zirconia, and stainless steel, which are suitable for the 5–15°C chamber temperature range without condensation issues.
What electrical and installation infrastructure is needed to support the XQM-0.4's integrated air cooling system in a standard laboratory?
The XQM-0.4 requires a standard electrical supply for its 250W grinding motor; the air cooling unit operates on the air-conditioning compression principle, using ambient air for heat exchange and needing no external coolant or venting. The compact footprint of 530×300×360 mm and net weight of 34 kg allow benchtop installation, with no specialized infrastructure beyond a standard power outlet and adequate airflow around the unit.
The Atomfair XQM-0.4 Modified Planetary Ball Mill integrates an air-cooling refrigeration unit to maintain grinding chamber temperatures between 5-15°C, making it suitable for ultra-fine grinding of heat-sensitive materials. With a maximum rotation speed of 870 r/min and discharge particle size down to 0.1 μm, it delivers efficient nanoscale comminution for applications in ceramics, battery materials, and catalysts.
Positive
- Integrated air-cooling temperature control: The air cooling unit, based on air-conditioning compression refrigeration, circulates cold air to remove grinding heat, maintaining chamber temperature at 5–15°C to preserve material properties during high-speed milling.
- Ultra-fine grinding down to 0.1 μm: Planetary motion of jars and balls enables discharge particle sizes as low as 0.1 μm, depending on material and process, supporting nanoscale applications in advanced ceramics and electronic powders.
Trade-offs
- Feed particle size restrictions: Maximum feed size is ≤10 mm for soil materials and ≤3 mm for other materials, requiring pre-crushing for larger feed stocks before milling.
- Loading capacity limit of two-thirds jar volume: The combined volume of material and grinding balls must not exceed two-thirds of the jar volume, constraining batch throughput per cycle.
