Description

ATOMFAIR CPM-20 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-20 is a standard-type cryogenic planetary ball mill with a 4 kW motor and a jar rotation speed range of 0–430 rpm. The jar seat inner diameter is 222 mm with a planetary revolution diameter of Φ385 mm. The overall dimensions are 1200 × 790 × 930 mm with a net weight of approximately 392 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 1 L–20 L (total volume 4 L–80 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.

What is the achievable grinding temperature range of the PBM-20 and how does ambient temperature affect it?

The PBM-20 low temperature planetary ball mill can control the grinding chamber temperature at 5–15°C, depending on ambient temperature differences. The air cooling unit uses air-conditioning compression refrigeration to remove heat generated during grinding, but the actual chamber temperature is influenced by the surrounding environment.

Can the PBM-20 be used for grinding lithium-ion battery cathode materials like lithium cobalt oxide?

Yes, the PBM-20 is specifically designed for low-temperature grinding of heat-sensitive materials, and its listed applications include lithium cobalt oxide, lithium manganate, and other battery materials. The low temperature environment prevents thermal degradation during high-speed planetary ball milling.

Does the PBM-20 require a water chiller or external cooling system, or is it self-contained?

The PBM-20 integrates an air cooling unit based on air-conditioning compression refrigeration, making it a self-contained system that does not require an external water chiller or cooling water supply. It only needs standard electrical power (4kW) and adequate ventilation for the refrigeration unit.

The PBM-20 Low Temperature Planetary Ball Mill integrates an air-cooled refrigeration system to maintain grinding chamber temperatures between 5–15°C, preventing thermal degradation of heat-sensitive materials during high-energy planetary milling. Its 4kW motor drives four grinding jars in planetary motion for efficient ultrafine grinding, though jars and balls are sold separately.
