ball mill is a grinding machine used to grind, blend, and sometimes for mixing of materials for use in geology, ceramics, metallurgy, electronics, pharmacy, construction material, and light industry, etc. ball mills are classified as attritor, planetary ball mill, high energy ball mill, horizontal ball mill, or shaker mill.
feb 14, 2018 ball mill, a type of grinder, is a cylindrical device used in grinding materials like ores, chemicals, ceramic raw materials and paints. ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.
the taurus has several available configurations depending on the application and mill size. netzsch ecutec also carries an extensive selection of special grinding media to optimize the performance of the ball mill specific to the customers requirements.
grinding materials to a nano-scale is an important aspect of quality control and r&d. azom speaks to dr. tanja butt from retsch gmbh about the benefits of using high energy ball mills instead of planetary ball mills.
the grinding circuit includes the separation tank, mill recirculating pump, mill product tank, hydrocyclone, hydrocyclone feed pump and all necessary controls. due to the CL attritors high efficiency, the power consumption for this mill is 50% less compared to conventional ball mills of a similar size.
