  • Preparation of Ultrafine Metal Powder by Ball Milling Preparation of Ultrafine Metal Powder by Ball Milling

    Jan 22, 2021 Here, we would share the preparation method of ultra-fine metal powder - ball milling method in the mechanical method. The ball milling method is mainly divided into the rolling ball method and vibration ball milling method. This method uses the mechanism that metal particles are broken and refined due to deformation at different strain rates

    Tube mills consist of revolving cylinders, with a number of hard balls which act as the grinding media. Tube mills differ from ball mills essentially in having an inlet for material feed and an outlet for the ground material. Hence, tube mills have larger length to diameter ratio (≈3:1) as compared to
