Cryogenic Planetary Ball Mill CPM-(8-12)A ATOMFAIR®

ATOMFAIR CPM-(8-12)A CRYOGENIC PLANETARY BALL MILL 5-15°C LOW-TEMP GRINDING

RESEARCH & PRODUCTION GRADE EQUIPMENT

Product Overview

ATOMFAIR CPM-(8-12)A Cryogenic Planetary Ball Mill – key parameters: 1.5 kW gear-drive motor, 0–580 r/min (1:1.5) jar rotation, 275 mm revolution diameter, 162 mm jar holder ID, compatible with 4 × 2 L jars (total 8 L) or 4 × 3 L jars (total 12 L), output down to 0.1 μm, integrated 3P air-cooled refrigeration unit maintains 5–15°C.
The CPM-(8-12)A 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, compatible with 2 L or 3 L jars to accommodate different batch size requirements. This listing is priced for the CPM-(8-12)A 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.
Flexible Jar Compatibility – 2 L or 3 L Jars: The CPM-(8-12)A supports 4 standard 2 L jars (total 8 L) or 4 standard 3 L jars (total 12 L), providing versatility to adapt to different batch size requirements 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-(8-12)A 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: compatible with 4 × 2 L jars (total 8 L) or 4 × 3 L jars (total 12 L) – 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 control range of the CPM-(8-12)A cryogenic planetary ball mill, and how does ambient temperature affect it?

The integrated 3P air-cooled refrigeration unit maintains the grinding chamber between 5–15°C, but this range is dependent on ambient temperature conditions. The source states that stable temperature control requires a stable laboratory environment for consistent results, and adequate ventilation space around the equipment is necessary for optimal cooling performance.

Which jar materials are compatible with the CPM-(8-12)A for contamination-sensitive grinding applications?

The CPM-(8-12)A is compatible with 4×2L or 4×3L jars in materials including WC-Co, Al₂O₃, Agate, YSZ, stainless steel, polyurethane, ceramic, and nylon. The source explicitly advises selecting jar and ball materials compatible with your target material to avoid cross-contamination, and these jars are ordered separately.

What are the infrastructure requirements for installing the CPM-(8-12)A cryogenic ball mill?

The main unit weighs 150 kg and measures 880×560×642 mm. The integrated 3P air-cooled refrigeration unit requires adequate ventilation space around the equipment for optimal cooling performance. The source also notes that the temperature control range depends on ambient conditions, so a stable laboratory environment is recommended.

Assessment

The CPM-(8-12)A cryogenic planetary ball mill integrates a 3P air-cooled refrigeration unit to maintain 5-15°C grinding chamber temperature, critical for preserving physicochemical properties of temperature-sensitive materials. The gear-drive system with inverter speed control provides precise 0-580 rpm regulation and supports 4 x 2L or 4 x 3L jars for batch flexibility.

Positive

Integrated cryogenic temperature control: Air-cooled compressor-based refrigeration system maintains stable 5-15°C grinding chamber temperature, preventing heat-induced alteration of physicochemical properties during high-speed grinding.
Gear drive with stepless speed control: Gear-driven transmission provides robust torque for heavy loads, and brand inverter enables precise stepless speed regulation across 0-580 rpm for optimized grinding parameters.

Trade-offs

Ambient temperature dependency: The 5-15°C temperature control range depends on ambient laboratory conditions; stable environmental temperature is required for consistent performance.
Separate jar and media procurement: Grinding jars and balls are not included and must be ordered separately; careful material selection is needed to avoid cross-contamination with target samples.
