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
Low temperature planetary ball mill is widely used in geology, mineral resources, metallurgy, electronics, building materials, ceramics, chemical industry, light industry, medicine, environmental protection and other fields.It is suitable for the production of electronic ceramics, structural ceramics, magnetic materials, lithium cobalt oxide, lithium manganate, catalysts, fluorescent powders, long afterglow luminescent powders, rare earth polishing powders, electronic glass powders, fuel cells, zinc oxide varistors, piezoelectric ceramics, nanomaterials, wafer ceramic capacitors, MLCC, thermistors (PTC, NTC), zinc oxide varistors, dielectric ceramics, alumina ceramics, zirconia ceramics, fluorescent powders, zinc oxide powder, cobalt oxide powder, Ni-Zn ferrites, Mn-Zn ferrites and other products.
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 mill must be operated inside an inert gas glove box to prevent oxidation of sensitive materials. Grinding jars must be securely locked onto the 50 mm holders before startup to avoid ejection.
- Jar Size Constraint: Only use grinding jars with an outer diameter compatible with the 50 mm holder ID to ensure proper fit and balance.
- Speed Limit: Do not exceed the maximum rotation speed of 1160 r/min to prevent mechanical failure and material leakage.
- Temperature Range: The integrated air cooling unit controls the grinding chamber between 5 and 15°C; avoid operation outside this range.
- Inert Atmosphere Requirement: Maintain a continuous inert gas flow (e.g., argon) inside the glove box to preserve material integrity during grinding.
This procedure covers the startup and operation of the mill under inert gas conditions. Follow these steps to ensure safe grinding with controlled temperature and atmosphere.
Required Equipment: Inert gas glove box, Grinding jar set (50 mm holder compatible), Grinding balls (specified for material and jar size), Inert gas supply (argon or nitrogen)
- Position the mill and connect inert gas
Place the mill inside the glove box and connect the inert gas supply to maintain a controlled atmosphere. - Prepare grinding jars
Fill each grinding jar with the sample and appropriate grinding balls, then seal the jars tightly. - Install jars on holders
Fasten the prepared jars securely onto the 50 mm holders of the mill to prevent loosening during rotation. - Set cooling temperature
Set the air cooling unit to the desired temperature within the range of 5 to 15°C using the control panel. - Adjust rotation speed
Set the rotation speed within the allowed range of 0 to 1160 r/min according to the grinding requirements. - Purge and seal glove box
Close the glove box and purge with inert gas until the oxygen and moisture levels are below acceptable thresholds. - Start milling and monitor
Start the mill and periodically monitor both the chamber temperature and the inert atmosphere levels during operation.
How does the air cooling system on the XQM-0.2S maintain temperature control across the full grinding speed range without compromising throughput?
The XQM-0.2S uses an air-conditioning compression refrigeration unit that circulates cold air to maintain a grinding chamber temperature of 5–15°C independently of the rotation speed (0–1160 r/min), so there is no trade-off between cooling capacity and maximum rpm. However, to achieve the minimum discharge particle size of 0.1 μm, the feed material (non-soil) must be ≤3 mm, which is a feed-size constraint that directly affects final fineness.
What are the spatial and electrical integration requirements for installing the XQM-0.2S inside a glove box for inert gas operation?
The XQM-0.2S consists of a main unit (390×220×270 mm) and a separate control box (200×180×240 mm), both small enough to fit inside a standard glove box. It requires a 90W, single-phase electrical feedthrough and uses a gear drive transmission with stepless frequency converter speed control, enabling simultaneous operation of two or four grinding jars with a holder ID of 50 mm.
What safety and infrastructure measures are required for operating the XQM-0.2S with its air cooling system in an inert gas environment?
The air cooling unit is a closed-loop compression system that does not require external coolant or water lines, but the glove box must have a continuous inert gas supply to prevent condensation inside the grinding chamber and to maintain an oxygen-free atmosphere. The mill weighs 29 kg and has a maximum loading capacity of two-thirds the jar volume per jar to avoid mechanical overpressure during high-speed planetary motion.
The Atomfair XQM-0.2S is a compact planetary ball mill with integrated air cooling for temperature-controlled grinding at 5-15°C, designed for operation in inert gas glove boxes. Its small capacity and limited temperature range constrain throughput and applications requiring sub-ambient conditions.
Positive
- Controlled low-temperature grinding: Integrated air cooling device maintains grinding chamber at 5-15°C, preventing heat-induced degradation of temperature-sensitive materials during high-speed planetary milling.
- Inert gas environment compatibility: The 'S' model (glove box type) is designed for direct integration into inert gas glove boxes, enabling processing of air-sensitive or reactive samples without atmospheric contamination.
Trade-offs
- Limited temperature range: Cooling system only achieves 5-15°C, insufficient for cryogenic grinding applications requiring sub-zero or deep-freeze conditions.
- Small sample throughput capacity: Mini design with 50 mm jar holder ID and 90 W motor restricts batch volume to a few hundred milliliters, limiting throughput for larger-scale preparation.
