Description

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

RESEARCH GRADE EQUIPMENT

Product Overview
This equipment 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 where strict temperature control is critical. The air-cooled refrigeration gear drive 0.1μm 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 2 or 4 grinding jars with single jar volumes from 5 L to 50 L (total volume 20 L–200 L). This listing is priced for the 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.

Technical Specifications
The ATOMFAIR CPM-(8-12)A is a semi-circular cryogenic planetary ball mill with a 1.5 kW motor and a jar rotation speed range of 0–580 rpm. The jar seat inner diameter is 162 mm with a planetary revolution diameter of Φ275 mm. The overall dimensions are 880 × 560 × 642 mm with a net weight of approximately 150 kg. The transmission system employs gear drive with brand-name inverter stepless speed regulation. The working mode supports simultaneous operation of 2 or 4 grinding jars, each with a single jar volume of 0.25 L–5 L (total volume 1 L–20 L), and a maximum loading capacity (material plus balls) of two-thirds of the jar volume. The machine accepts feed sizes of ≤10 mm for soil samples and ≤3 mm for other materials, delivering output fineness down to 0.1 μm depending on material properties and grinding process parameters. The integrated air-cooled refrigeration unit uses compressor-based cooling with cold air circulation to stably maintain the grinding chamber temperature between 5–15°C.

The grinding chamber temperature must be maintained between 5 and 15°C to prevent thermal degradation of temperature-sensitive materials. Only grinding jars and balls that are mechanically and thermally compatible with low-temperature operation should be used to avoid failure or contamination.

  • Temperature Control Constraint: Operate the refrigeration unit continuously during grinding to keep the chamber within the specified 5–15°C range and prevent overheating of the sample and equipment.
  • Jar and Ball Compatibility: Use only grinding jars and balls that are rated for low-temperature service and properly balanced to minimize vibration and mechanical stress on the planetary drive.
  • Electrical Safety Constraint: Ensure the 1.5 kW motor and refrigeration unit are connected to a grounded electrical supply to mitigate the risk of electric shock or short circuit.
  • Pre-Operation Inspection: Inspect the air cooling unit and planetary mechanism for any signs of damage or refrigerant leaks before each use.

This procedure outlines the steps to safely initialize and operate the low temperature planetary ball mill for controlled grinding. Adherence to these steps minimizes mechanical and thermal hazards while ensuring proper temperature management.

Required Equipment: Grinding jars and balls, Refrigeration control panel

  1. Inspect Components
    Inspect the grinding jars and balls for cracks, wear, or contamination and confirm they are clean and dry before loading the sample.
  2. Load and Secure Jars
    Fill the grinding jars with the sample and balls, balance them by weight, and secure them onto the planetary disc using the locking mechanism.
  3. Set Temperature
    Set the desired grinding chamber temperature between 5 and 15°C on the control panel and allow the refrigeration unit to pre-cool the chamber.
  4. Start Grinding Cycle
    Begin the grinding cycle at the lowest rotational speed and gradually increase to the target speed while monitoring the chamber temperature.
  5. Post-Operation Shutdown
    Allow the machine to return to ambient temperature after stopping rotation before opening the lid to prevent condensation or thermal shock.

What is the maximum grinding jar rotation speed of the low-temperature PBM-8A model, and does the air cooling system reduce the available speed range compared to the standard PBM-8?

The maximum grinding jar rotation speed for the PBM-8A low-temperature model is 0–570 r/min, identical to the standard PBM-8. The air cooling unit operates independently of the drive system and does not impose any speed reduction. The cooling system uses cold air circulation to remove heat without affecting the mill's rotational performance.

How many grinding stations does the low-temperature PBM-8A have, and what is the maximum jar outside diameter that can be accommodated?

The low-temperature PBM-8A planetary ball mill has four grinding stations (four jars). The grinding jar holder inner diameter is 170 mm, as listed in the technical parameter table for both PBM-8A and PBM-12A models. This determines the maximum jar outside diameter that can be installed.

Does the low-temperature planetary ball mill require an external water chiller or water supply for cooling?

No, the low-temperature planetary ball mill uses an air cooling unit based on air-conditioning compression refrigeration principle. It does not require an external water supply or chiller. The system uses cold air circulation to remove heat, providing a simple and low-energy cooling solution as stated in the product features.

The PBM-8-12 Low Temperature Planetary Ball Mill integrates a planetary ball mill with an air-cooling refrigeration unit to maintain grinding chamber temperatures between 5–15°C, preventing thermal degradation of heat-sensitive materials during high-energy milling. Its versatile design supports a wide range of advanced material applications, though users must separately procure grinding jars and balls and account for ambient temperature influences on cooling performance.
