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.

This low-temperature planetary ball mill integrates an air cooling system to maintain grinding chamber temperatures between 5–15 °C. The equipment contains high-speed rotating components and electrical systems requiring proper grounding and operational safeguards.
- Temperature Control: The air cooling unit must be active and functional to prevent overheating of materials during grinding.
- Mechanical Safety: All four grinding jars must be symmetrically loaded and securely clamped to the main disc before operation.
- Material Compatibility: Identify materials prone to exothermic reactions to assess additional cooling requirements prior to grinding.
- Electrical Safety: Operate the mill only with a power supply matching the motor’s rated specifications to avoid electrical hazards.
- Post-Operation: Allow the mill to come to a complete stop before opening the chamber or handling the jars.
This procedure outlines the safe operation of the low-temperature planetary ball mill for grinding temperature-sensitive materials. Adhere to temperature and speed settings to maintain material integrity during processing.
Required Equipment: Grinding jar assembly, Air cooling unit

Set the desired rotation speed and grinding duration using the control panel. - Start the mill
Start the mill and monitor the chamber temperature throughout the grinding cycle. - Stop the mill
After the set time has elapsed, stop the mill and wait for all rotating parts to come to rest. - Retrieve samples
Open the chamber and remove the grinding jars for sample retrieval and cleaning.
Does the air-cooled low-temperature system on the XQM-20 limit the maximum rotation speed or achievable discharge particle size compared to a standard planetary ball mill without refrigeration?
No, the air cooling system does not impose a rotation speed limit; the XQM-20 achieves 0–430 r/min regardless of cooling operation. The minimum discharge particle size remains 0.1 μm as stated for the planetary ball mill, because the cooling prevents heat-induced material changes that could otherwise degrade grinding efficiency. The low-temperature feature thus preserves particle size performance while controlling the grinding environment.
Can the XQM-20 low temperature ball mill be used directly inside a glove box for processing air-sensitive lithium battery cathode materials like NMC or LFP?
The product description does not list a glove-box-compatible version for the XQM-20 model; only the mini glove box type XQM-0.2S is offered. The XQM-20 is a standalone unit with overall dimensions 1200 × 790 × 930 mm and net weight 392 kg, making integration into a standard glove box impractical. For inert-atmosphere processing, users must consider sealed jar systems or alternative models.
What are the electrical, ventilation, and floor-loading infrastructure requirements for installing the XQM-20 low temperature ball mill in a typical materials research laboratory?
The XQM-20 requires a 4 kW electrical supply via a frequency converter for stepless speed regulation. The air cooling unit uses compression refrigeration and must have unobstructed ventilation to reject heat; the grinding chamber temperature is controlled at 5–15 °C depending on ambient conditions. The unit weighs 392 kg and measures 1200 × 790 × 930 mm, so a reinforced floor or heavy-duty bench rated for at least 400 kg is necessary.
The XQM-20 integrates a planetary ball mill with an air cooling system to maintain grinding chamber temperatures between 5–15°C, enabling ultra-fine grinding down to 0.1 μm for heat-sensitive materials like lithium battery compounds and ceramics. This model features a 20L total jar capacity (5L per jar) with gear drive and stepless frequency converter speed control.
Positive
- Integrated air cooling for heat-sensitive materials: The air cooling unit, based on air-conditioning compression refrigeration, circulates cold air to maintain the grinding chamber at 5–15°C, preventing thermal degradation of materials like lithium cobalt oxide or nano powders during high-speed grinding.
- Ultra-fine grinding down to 0.1 μm: The planetary ball mill achieves discharge particle sizes as small as 0.1 μm, varying with material and process, which is critical for advanced ceramics, electronic pastes, and nano-structured materials.
Trade-offs
- Limited temperature control range: The air cooling system constrains the grinding chamber temperature to 5–15°C, which may not be suitable for processes requiring sub-zero conditions or ambient temperatures above 15°C without additional cooling infrastructure.
- Feed particle size constraints: Maximum feed particle size is 10 mm for soil and 3 mm for other materials, requiring pre-crushing for larger feed stocks to avoid damaging the mill or reducing grinding efficiency.
