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.

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.

We also provide grinding jars of various materials: agate, alumina corundum ceramics, zirconia ceramics, silicon nitride ceramics, silicon carbide ceramics, stainless steel, wear-resistant steel, manganese steel, nylon, polyurethane, cemented carbide, crystal glass, etc.”
This equipment requires strict temperature control within 5–15°C during operation to avoid compromising heat-sensitive materials. The air cooling system necessitates regular filter cleaning to ensure efficient heat dissipation and prevent electrical overloading.
- Chamber Temperature Control: Maintain the grinding chamber temperature between 5°C and 15°C to prevent thermal degradation of samples.
- Cooling Unit Maintenance: Clean the air cooling unit filters periodically to sustain cooling performance and reduce strain on the refrigeration compressor.
What is the maximum feed particle size for soil materials compared to other materials when using the XQM-6 planetary ball mill, and how does this influence the achievable minimum discharge fineness?
The XQM-6 accepts soil materials up to 10 mm and other materials up to 3 mm feed particle size. The minimum discharge particle size can reach 0.1 μm, but the actual fineness depends on the material properties and grinding process parameters, including grinding jar speed, ball-to-material ratio, and duration.
Can the XQM-6 low-temperature planetary ball mill process lithium-ion battery cathode materials such as lithium cobalt oxide and lithium manganate without thermally degrading their crystal structure?
Yes, the XQM-6 is specifically designed for grinding temperature-sensitive materials like lithium cobalt oxide and lithium manganate. The integrated air cooling system maintains the grinding chamber at 5–15°C, preventing heat-induced phase changes or decomposition during high-speed planetary milling.
What electrical power supply and laboratory footprint are required to install the Atomfair XQM-6 low-temperature planetary ball mill?
The XQM-6 requires a 0.75 kW motor power supply and occupies a footprint of 760 × 470 mm with a height of 580 mm. The unit weighs 100 kg and is suitable for benchtop installation with adequate ventilation for the air cooling system.
The Atomfair XQM-6 integrates an air-cooled refrigeration unit to maintain grinding chamber temperatures between 5–15°C, preventing thermal degradation of heat-sensitive materials during planetary ball milling. With a 0.75 kW motor and rotation speeds up to 670 r/min, it achieves discharge fineness down to 0.1 μm, making it suitable for ultra-fine grinding of ceramics, battery materials, and catalysts in laboratory or pilot-scale operations.
Positive
- Low-temperature grinding preserves material properties: Integrates an air-cooling unit that controls the grinding chamber at 5–15°C, counteracting heat from friction or exothermic reactions to prevent unwanted changes in physical or chemical characteristics.
- Ultra-fine grinding capability down to 0.1 μm: The planetary motion with gear drive and stepless speed control enables consistent milling to submicron particle sizes, essential for advanced functional materials and battery precursor synthesis.
Trade-offs
- Temperature control depends on ambient conditions: The 5–15°C chamber range is achieved relative to ambient temperature differences; in hot or poorly ventilated environments, the cooling efficiency and achievable low temperature may be compromised.
- Feed particle size limits require pre-processing: Maximum feed size is 10 mm for soil and 3 mm for other materials; larger particles must be pre-crushed before milling, adding an extra step to the workflow.
