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.

Supporting Products
We also supply various grinding balls: stainless steel balls, zirconia balls, alumina balls, PU balls, carbon steel balls, tungsten balls, agate balls, cemented carbide balls, silicon nitride balls, high wear-resistant steel balls, manganese steel balls, nylon balls, cemented carbide, glass and other special metal materials.
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.”
The device requires a stable, grounded electrical supply and adequate space for airflow around the refrigeration unit. Grinding jars must be securely fastened and balanced to avoid mechanical stress during high-speed rotation.
- Electrical Safety: Ensure the mains power supply matches the motor rating and includes overcurrent protection.
- Mechanical Balance: Verify that all grinding jars and contents are symmetrically loaded to prevent excessive vibration.
- Temperature Monitoring: Monitor the grinding chamber temperature during operation to stay within the 5–15°C range.
- Refrigeration Airflow: Keep the air intake and exhaust vents of the cooling unit unobstructed at all times.
- Material Compatibility: Only process materials that are non-explosive and chemically compatible with the jar and ball materials under low-temperature conditions.
The low temperature planetary ball mill combines high-energy grinding with active cooling for temperature-sensitive materials. Proper installation of jars, balls, and material followed by sequential startup of cooling and rotation ensures safe and efficient operation.
Required Equipment: Grinding Jars, Grinding Balls, Air Cooling Unit
- Install Grinding Jars and Balls
Secure the grinding jars onto the planetary disc and add the appropriate grinding balls and sample material. - Set Cooling Parameters
Activate the air cooling unit and allow the chamber temperature to stabilize at the desired set point between 5–15°C. - Configure Rotation Speed and Time
Set the variable frequency drive to the required rotation speed and grinding duration using the control panel. - Start Grinding Cycle
Engage the motor to begin planetary motion and monitor the process for abnormal vibrations or temperature deviations. - Stop and Unload
After the cycle completes, stop the motor, allow the jars to cool if necessary, and carefully remove the ground material.
How does the air-cooled temperature control between 5–15°C affect the grinding speed and throughput of the XQM-60 for exothermic materials like lithium cobalt oxide?
The XQM-60's air cooling unit maintains the grinding chamber at 5–15°C using air-conditioning compression refrigeration, enabling ultra-fine grinding of heat-sensitive materials such as lithium cobalt oxide without thermal degradation. However, the maximum grinding jar rotation speed is limited to 260 r/min (1:1.5 speed ratio) compared to smaller models, which may reduce throughput for materials that do not require such low temperatures. The trade-off ensures that exothermic reactions do not alter material properties during high-speed grinding.
Can the XQM-60 process both soft soil materials (≤10 mm feed) and hard ceramics (≤3 mm feed) in the same grinding session without risk of contamination or damage?
Yes, the XQM-60 accepts feed sizes up to 10 mm for soil materials and up to 3 mm for other materials, with a minimum discharge fineness of 0.1 μm. However, for hard ceramics like alumina or zirconia, dedicated grinding jars and media must be selected to prevent cross-contamination. The planetary ball mill uses gear drive and can operate with two or four jars simultaneously, allowing separate processing of different materials if jar sets are changed between runs.
What electrical and spatial infrastructure is required to install and operate the 950 kg XQM-60 planetary ball mill with air cooling?
The XQM-60 requires a 7.5 kW motor and dimensions of 1600×1070×1250 mm, with a net weight of 950 kg. The air cooling unit needs adequate ventilation for heat dissipation and is powered through the main electrical supply. Stepless speed control via a brand frequency converter ensures stable operation, but laboratory floors must support the weight, and clearance for jar loading and maintenance is necessary.
The Atomfair XQM-60 low temperature planetary ball mill integrates a refrigeration air cooling system to maintain grinding temperatures between 5-15°C, enabling ultra-fine grinding down to 0.1μm for heat-sensitive materials. With a total jar capacity up to 200L and 7.5 kW motor, it is suited for large-volume processing but requires pre-milling of feed materials due to a maximum input size of 3mm and demands robust infrastructure given its 950 kg weight and 1.6m x 1.07m footprint.
Positive
- Integrated cooling to 5-15°C: The built-in air conditioning type refrigeration unit actively removes heat generated during grinding, maintaining the chamber at 5-15°C to prevent thermal degradation of temperature-sensitive materials.
- Large volume and high throughput: Configured with up to four grinding jars each holding 5–50 L, the XQM-60 can process total volumes of 20–200 L per batch, making it suitable for production-scale ultra-fine grinding.
Trade-offs
- Feed size limitation: Maximum feed particle size is 10 mm for soil and only 3 mm for other materials, necessitating pre-milling or crushing of larger particles before introduction into the mill.
- Moderate cooling range: The cooling system is limited to a chamber temperature of 5–15°C, which may not suffice for cryogenic applications requiring sub-zero processing conditions.
