Once the application requirements are clear, a suitable mill can be selected. To facilitate this process, Retsch displays the strength and efficiency of each ball mill model in a spider-net diagram, see Figure 3. A planetary ball mill, for example, offers a big jar volume compared to a mixer mill and shows a high value on this diagonal.
Ball mill is a type of grinding equipment that uses the rotary cylinder to bring the grinding medium and materials to a certain height and make them squeeze, impact, and grind and peel each other to grind materials.
