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.

How effectively can the Atomfair XQM-0.2 maintain its 5–15°C grinding chamber temperature when operating at the maximum speed of 1160 r/min?
The air cooling unit, based on air-conditioning compression refrigeration, maintains the grinding chamber at 5–15°C regardless of ambient temperature differences, even during high-speed grinding at 1160 r/min. This is achieved through continuous cold air circulation that rapidly removes frictional heat, ensuring stable low-temperature conditions for heat-sensitive materials.
What are the feed particle size and loading constraints for grinding battery cathode materials like lithium cobalt oxide or lithium manganate in the XQM-0.2?
For all materials other than soil, the feed particle size must be ≤3 mm, while soil materials can be up to ≤10 mm. The combined volume of material and grinding balls must not exceed two-thirds of the jar volume. These constraints apply to the XQM-0.2's 50 mm jar holder ID and ensure efficient ultra-fine grinding down to 0.1 μm.
Does the air cooling system on the XQM-0.2 require external water supply or special ventilation infrastructure for safe laboratory operation?
No external water or dedicated venting is required; the cooling system uses sealed compression refrigeration and recirculating cold air. The unit's 90W motor and compact 420×260×310 mm footprint only need standard electrical power and sufficient bench space for ambient air circulation around the condenser to maintain cooling efficiency.
The Atomfair XQM-0.2 Mini Compact Low Temperature Planetary Ball Mill integrates an air cooling unit to maintain grinding chamber temperature between 5-15°C, enabling ultra-fine grinding down to 0.1μm for heat-sensitive materials. Its compact design, stepless speed control up to 1160 r/min, and 90W motor make it suitable for small-batch R&D processing in laboratories requiring strict thermal management.
Positive
- Integrated air cooling for thermal control: The built-in air cooling unit uses compression refrigeration to circulate cold air, maintaining grinding chamber temperature at 5–15°C to prevent heat-induced degradation of temperature-sensitive materials.
- Ultra-fine grinding down to 0.1 μm: The planetary ball mill achieves discharge particle sizes as fine as 0.1 μm (100 nm), enabling high-precision comminution for advanced materials like ceramics, catalysts, and battery compounds.
Trade-offs
- Temperature range constrained by ambient: The chamber temperature is regulated to 5–15°C, a range dependent on ambient temperature differences; it cannot achieve sub-zero or higher temperatures required for certain specialized processes.
- Maximum charge volume limited to two-thirds jar capacity: Total material and grinding balls must not exceed two-thirds of the jar volume, reducing effective batch throughput per grinding cycle.
