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 a planetary grinder with an air cooling unit for controlled processing of heat-sensitive materials. The grinding chamber temperature must be maintained between 5 and 15 degrees Celsius to prevent thermal degradation of the sample.
- Material Suitability: The mill is designed exclusively for heat-sensitive materials that require low-temperature processing.
- Temperature Control Requirement: The air cooling unit must be operational during grinding to maintain the chamber temperature within the specified 5-15°C range.
This procedure describes the safe and effective operation of the low temperature planetary ball mill for grinding heat-sensitive materials. Following these steps ensures proper temperature control and prevents material degradation.

What is the trade-off between grinding speed and temperature control in the XQM-16A, and how does the 510 r/min maximum speed affect the achievable particle size for heat-sensitive ceramics?
The XQM-16A operates at a maximum jar rotation speed of 510 r/min, which is lower than ambient-temperature models to accommodate the air cooling system that maintains 5–15°C. This reduced speed still enables ultra-fine grinding down to 0.1 μm, but the throughput per cycle may be lower compared to high-speed mills. The 3KW motor and gear drive ensure sufficient torque for the half-round jar configuration.
What are the maximum feed and jar volume constraints for processing soil materials in the XQM-16A low temperature planetary ball mill?
For the XQM-16A, the feed particle size must be ≤10mm for soil materials and ≤3mm for others. The jar volume per jar is 5L–50L (specific to model), and the total loading of material plus grinding balls must not exceed two-thirds of the jar volume to avoid overloading the gearing and cooling system.
What are the recommended operating conditions and space requirements for installing the XQM-16A air-cooled planetary ball mill in a laboratory?
The XQM-16A requires a 3KW power supply for the variable frequency drive, a sturdy bench capable of supporting 205kg, and dimensions of 950×600×710mm footprint. The air cooling unit exhausts warm air, so the lab should have adequate ventilation to prevent ambient temperature rise and ensure stable 5–15°C grinding chamber control.
The XQM-16A integrates a planetary ball mill with an air-cooling refrigeration system to maintain a 5–15°C grinding chamber, enabling ultra-fine grinding of heat-sensitive ceramic and battery materials without thermal degradation. Its 3KW gear drive and variable frequency speed control provide reproducible process optimization, though pre-crushing to ≤3mm feed is required and the cooling unit adds operational complexity.
Positive
- Active low-temperature control (5–15°C): Integrated air-cooling refrigeration removes heat generated during grinding, preventing thermal alteration of heat-sensitive materials like electronic ceramics, lithium cobalt oxide, and pharmaceutical compounds.
- Stepless variable frequency speed regulation: The 3KW motor with frequency converter enables infinite adjustment of rotation speed (up to 510 r/min), allowing precise tuning of grinding intensity for different material hardness and desired particle size (down to 0.1 μm).
Trade-offs
- Feed size limitation requires pre-crushing: Maximum feed particle size is 10 mm for soil materials but only 3 mm for others, necessitating a primary crushing step for most feedstocks before introducing them to the mill.
- Cooling system adds energy and maintenance overhead: The air conditioning compression refrigeration unit increases total power consumption and introduces additional components (compressor, condenser, fans) that require periodic maintenance, unlike passive-cooled planetary mills.
