Description

ATOMFAIR CPM-4A 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-4A is a semi-circular cryogenic planetary ball mill with a 0.75 kW motor and a jar rotation speed range of 0–670 rpm. The jar seat inner diameter is 134 mm with a planetary revolution diameter of Φ234 mm. The overall dimensions are 760 × 470 × 600 mm with a net weight of approximately 85 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 0.1L–3L (total volume 0.4L–12L), 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.
