Cryogenic Planetary Ball Mill CPM-40 40 L ATOMFAIR®

ATOMFAIR CPM-40 CRYOGENIC PLANETARY BALL MILL 5-15°C LOW-TEMP GRINDING

RESEARCH & PRODUCTION GRADE EQUIPMENT

Product Overview

ATOMFAIR CPM-40 Cryogenic Planetary Ball Mill – key parameters: 5.5 kW gear-drive motor, 0–390 r/min (1:1.5) jar rotation, 430 mm revolution diameter, 250 mm jar holder ID, total volume 40 L (4 jars × 10 L each), output down to 0.1 μm, integrated 3P air-cooled refrigeration unit maintains 5–15°C.
The CPM-40 combines a planetary ball mill with an air-cooled refrigeration unit based on compressor-type cooling principles. During high-speed grinding, most materials generate temperature rise through friction and exothermic reactions, which can alter physicochemical properties and compromise grinding results. This cryogenic planetary ball mill is specifically designed for low-temperature ultrafine grinding research and small-batch production where strict temperature control is critical. The air-cooled refrigeration gear drive system rapidly removes grinding-generated heat through cold air circulation, stably maintaining the grinding chamber temperature between 5–15°C depending on ambient temperature differential. The gear-driven transmission supports simultaneous operation of 4 grinding jars with 4 standard 10 L jars (total volume 40 L). This listing is priced for the CPM-40 main unit only—grinding jars and grinding balls are ordered separately. The CPM series spans from 0.2 L miniature models to 200 L production units with integrated cryogenic temperature control.

Key Features & Advantages

Integrated Air-Cooled Refrigeration with 5–15°C Temperature Stability: The compressor-based cooling system rapidly removes frictional and exothermic reaction heat via cold air circulation, stably maintaining the grinding chamber within the 5–15°C range for temperature-sensitive materials processing.
Gear-Driven Transmission with Brand Inverter Stepless Speed Control: The gear drive system delivers robust torque transmission for heavy grinding loads, while the brand-name inverter enables precise stepless speed regulation across the full operational range for optimized grinding parameters.
Ultrafine Output Down to 0.1 μm with High Loading Capacity: The planetary motion achieves final particle sizes as fine as 0.1 μm depending on material and process parameters, with maximum loading of two-thirds jar volume for efficient batch processing.
Mid-Scale Production Capacity with 40 L Total Volume (4 × 10 L): The CPM-40 supports 4 standard 10 L grinding jars for a total volume of 40 L, offering an ideal balance between production throughput and laboratory-scale flexibility while maintaining consistent cryogenic temperature control across all jars.

APPLICATION SCOPE: Widely used in geology, mining, metallurgy, electronics, building materials, ceramics, chemical engineering, light industry, pharmaceuticals, and environmental protection for temperature-sensitive materials. Specifically suitable for electronic ceramics, structural ceramics, magnetic materials, lithium cobalt oxide, lithium manganese oxide, catalysts, phosphors, long-afterglow luminescent powders, rare-earth polishing powders, electronic glass powders, fuel cells, zinc oxide varistors, piezoelectric ceramics, nanomaterials, multilayer ceramic capacitors (MLCC), thermistors (PTC, NTC), dielectric ceramics, alumina ceramics, zirconia ceramics, zinc oxide powders, cobalt oxide powders, nickel-zinc ferrites, and manganese-zinc ferrites where low-temperature grinding is critical for preserving material properties.

PACKAGING: This listing is priced for the CPM-40 main unit only. The standard configuration includes 1 pc grinding host machine with integrated air-cooled refrigeration unit (3P compressor), brand-name inverter speed control, and gear drive transmission. Grinding jars: 4 pcs of 10 L (total volume 40 L) are ordered separately. Grinding balls are also ordered separately. The CPM series is available from 0.2 L miniature models through 200 L production units. Installation guidance and operational training support are provided upon request.

IMPORTANT NOTICE: The listed price is for the main unit; grinding jars and balls must be ordered separately. Select jar and ball materials compatible with your target material to avoid cross-contamination. The refrigeration unit requires adequate ventilation space around the equipment for optimal cooling performance. The temperature control range of 5–15°C is dependent on ambient temperature conditions—maintain a stable laboratory environment for consistent results. For detailed installation, operation, and maintenance instructions, consult the user manual prior to first use.

FAQ

What is the effective temperature range of the CPM-40 cryogenic planetary ball mill under varying ambient conditions?

The CPM-40 maintains grinding chamber temperature between 5–15°C, but this range is dependent on ambient temperature differential. The integrated 3P air-cooled refrigeration unit rapidly removes heat via cold air circulation, but a stable laboratory environment is required for consistent results.

Which grinding jar materials are recommended for the CPM-40 when processing lithium cobalt oxide or other battery cathode materials to prevent contamination?

For battery cathode materials like lithium cobalt oxide, compatible jar materials include Al₂O₃ (95% alumina), YSZ (yttria-stabilized zirconia), and agate (natural SiO₂) to avoid cross-contamination. The CPM-40 accepts 4 × 10 L jars made from WC-Co, Al₂O₃, Agate, YSZ, stainless steel, polyurethane, ceramic, or nylon, and grinding balls must be selected accordingly.

What are the electrical and ventilation requirements for installing the CPM-40 cryogenic planetary ball mill?

The CPM-40 requires a 5.5 kW gear-drive motor with a 3P air-cooled refrigeration unit, meaning a three-phase power supply is needed. Adequate ventilation space around the equipment is essential for optimal cooling performance of the compressor-based system. The unit dimensions are 1400×880×1070 mm and weight 656 kg, requiring a sturdy floor and sufficient clearance.

Assessment

The Atomfair CPM-40 Cryogenic Planetary Ball Mill delivers 40 L total capacity (4×10 L jars) with an integrated air-cooled refrigeration system maintaining 5–15°C, enabling low-temperature ultrafine grinding down to 0.1 μm for temperature-sensitive materials such as battery cathodes, ceramics, and catalysts.

Positive

Integrated cryogenic temperature control: The compressor-based air-cooled refrigeration unit maintains grinding chamber temperature between 5–15°C, preventing thermally induced degradation in temperature-sensitive materials like lithium cobalt oxide and nano-scale ceramics.
Gear drive with stepless speed control: The 5.5 kW gear-driven transmission provides robust torque for heavy loads, while the brand inverter enables precise 0–390 r/min stepless speed regulation for optimized grinding parameters across different materials.

Trade-offs

Jars and media ordered separately: The main unit does not include grinding jars or balls; users must purchase 4×10 L jars and compatible media separately, adding procurement complexity and cost.
Temperature control depends on ambient conditions: The 5–15°C stability range is relative to ambient temperature; a stable laboratory environment and adequate ventilation around the refrigeration unit are required to maintain consistent cooling performance.
