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 device requires continuous monitoring of grinding chamber temperature and cooling system performance. Operation must follow electrical safety protocols and mechanical hazard precautions.
- Temperature Control: Maintain grinding chamber temperature between 5°C and 15°C to prevent thermal degradation of heat-sensitive materials.
- Electrical Safety: Ensure electrical connections are rated for the motor power (0.75 kW) and that the unit is properly grounded.
- Mechanical Hazard: Keep hands and loose items clear of rotating main disc and jar holders during operation.
- Refrigeration System: Verify the air cooling unit is functioning before initiating grinding to avoid overheating.
- Material Containment: Seal grinding jars tightly to contain sample and prevent release of fine particulates or reactive dusts.
Follow these steps to initialize and operate the grinder for heat-sensitive materials. Proper sequence ensures safe temperature control and efficient grinding.

How does the XQM-4A's low-temperature grinding capability affect the throughput compared to a standard ambient-temperature planetary ball mill when processing heat-sensitive materials?
The XQM-4A achieves the same minimum discharge particle size of 0.1 μm as standard planetary ball mills but with the added advantage of maintaining the grinding chamber at 5–15°C via the integrated air cooling unit. This allows continuous operation without intermittent cooling pauses, thereby increasing effective throughput for heat-sensitive materials that would otherwise require stop-and-cool cycles to prevent thermal degradation.
What types of jar materials are compatible with the XQM-4A's low-temperature environment, and are there any restrictions on jar volume for heat-sensitive applications?
The XQM-4A accommodates grinding jars with volumes from 5L to 50L per jar, with up to four jars operating simultaneously on the half-round type holder using gear drive. While the product description does not list specific jar materials, standard planetary mill jars such as stainless steel, zirconia, agate, and nylon are compatible, provided they do not exhibit thermal contraction or embrittlement at the operating temperature range of 5–15°C.
What electrical and spatial considerations are necessary for installing the XQM-4A, and does the air cooling unit require additional venting or a dedicated cooling water supply?
The XQM-4A requires a 0.75 kW motor power supply and occupies a footprint of 760 mm × 470 mm with a height of 600 mm, weighing 85 kg. The air cooling unit operates on the air-conditioning compression refrigeration principle using cold air circulation, so it does not require a dedicated cooling water line; however, adequate ventilation around the unit is necessary to dissipate heat from the condenser.
The XQM-4A integrates a planetary ball mill with an air cooling unit to maintain grinding chamber temperatures between 5–15°C, enabling ultra-fine grinding of heat-sensitive materials without thermal degradation. Its gear drive and frequency converter provide stepless speed regulation, while the half-round type design offers compact dimensions. However, users must adhere to feed size limits and loading constraints for optimal performance.
Positive
- Low-temperature grinding capability: The integrated air cooling unit maintains grinding chamber temperature at 5–15°C, preventing heat-induced alterations in material properties during high-speed milling.
- Broad material applicability: Capable of processing diverse heat-sensitive materials across ceramics, electronics, batteries, and pharmaceuticals with discharge particle sizes down to 0.1 μm.
Trade-offs
- Feed particle size restrictions: Maximum feed size is 10 mm for soil materials and 3 mm for others; larger particles require pre-crushing before milling.
- Limited loading capacity per jar: The combined volume of material and grinding balls must not exceed two-thirds of the jar volume, constraining batch processing throughput.
