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 equipment integrates a planetary ball mill with an air cooling system to maintain grinding chamber temperature between 5 and 15°C. Safe operation requires proper electrical grounding, secure jar mounting, and functional cooling before initiating grinding.
- Temperature Control: The air cooling unit must be activated and verified to achieve the set temperature range before loading materials.
- Grinding Jar Compatibility: Only use grinding jars and media rated for the maximum rotation speed and compatible with the material's chemical properties.
- Vibration and Stability: The mill must be placed on a level, vibration-dampening surface and secured with all bolts tightened to prevent displacement during operation.
- Electrical Safety: Confirm that the power supply matches the motor rating and the unit is connected to a grounded outlet with overload protection.
- Material Loading: Do not exceed the recommended jar fill volume to avoid excessive pressure and unbalanced loads.
This process describes how to safely operate the Atomfair XQM-40 low temperature planetary ball mill for grinding heat-sensitive materials under controlled temperature conditions. Users must follow each step sequentially to prevent equipment damage and personal injury.
Required Equipment: Atomfair XQM-40 Planetary Ball Mill, Air Cooling Unit, Grinding Jars, Grinding Balls
- Inspect Equipment
Inspect the mill and cooling unit for any visible damage or loose components before operation. - Activate Cooling
Connect the air cooling unit to a suitable power source and set the desired chamber temperature between 5 and 15°C. - Prepare Grinding Jars
Load the grinding jars with the material and appropriate grinding balls, ensuring the lid is sealed tightly. - Mount Jars
Mount the jars onto the mill's jar holders and secure them with the clamping mechanism. - Set Parameters
Set the rotation speed and grinding time according to the material requirements, not exceeding the maximum rated speed. - Start Grinding
Start the mill and monitor the chamber temperature periodically to ensure it remains within the specified range. - Stop and Unload
Allow the mill to come to a complete stop before opening the jars to release any built-up pressure.
What is the trade-off between grinding speed and temperature control in the XQM-40 when processing heat-sensitive materials?
The XQM-40's air cooling system maintains the grinding chamber at 5–15°C, but its maximum rotation speed is 390 r/min, which is lower than smaller models like the XQM-0.2 (1160 r/min). This trade-off ensures temperature-sensitive materials such as lithium cobalt oxide or catalysts avoid thermal degradation during medium-batch ultra-fine grinding, though it reduces mechanical grinding intensity per unit time.
Can the XQM-40 accommodate grinding jar sizes beyond 50 liters for scale-up processing?
No, the XQM-40 is designed for medium-batch processing with jar volumes of 5L–50L per jar and a total system volume of 20L–200L. Its jar holder inner diameter is 250 mm, which cannot physically accommodate larger jars. For higher batch capacities, the XQM-60 (total volume up to 240L) or XQM-100 (up to 400L) with larger revolution diameters of Φ490 mm and Φ578 mm, respectively, are required.
What electrical and cooling infrastructure is required to operate the XQM-40 low temperature planetary ball mill?
The XQM-40 requires a 5.5 kW motor with a brand frequency converter for stepless speed regulation. The air cooling unit employs air-conditioning compression refrigeration and requires an ambient environment for cold air circulation; no external chiller or liquid coolant is needed. The unit weighs 656 kg with overall dimensions of 1400×880×1070 mm, necessitating a level, reinforced floor and adequate ventilation for heat dissipation.
The Atomfair XQM-40 low temperature planetary ball mill integrates an air cooling system for precise 5–15°C grinding, enabling ultra-fine milling down to 0.1 μm for heat-sensitive materials in medium-batch production.
Positive
- Precise low-temperature grinding control: The integrated air cooling system maintains the grinding chamber at 5–15°C, preventing heat-induced alterations to the physical and chemical properties of heat-sensitive materials during high-speed grinding.
- Ultra-fine particle capability: Achieves discharge particle sizes down to 0.1 μm under low-temperature conditions, facilitating nanoscale processing for advanced materials such as ceramics, catalysts, and battery powders.
Trade-offs
- Large footprint and weight: The XQM-40 measures 1400×880×1070 mm and weighs 656 kg, requiring dedicated floor space and adequate structural support for installation in the laboratory.
- Feed size limitations for non-soil materials: Non-soil feedstock must be pre-crushed to ≤3 mm before milling, adding a preprocessing step for materials with larger initial particle dimensions.
