Description
Available diameters range from 20-150mm, with smaller balls of 15mm & 17mm diameters also available. Although the smaller balls of 15mm & 17mm are less commonly used, they have been used effectively in fine grinding applications in industry. Our consulting team will be happy to elaborate further on the use of smaller sized balls for your required grind.
