Ball mill

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) 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. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Where Dry Milling Makes Sense

Oct 15, 2000Stainless steel can be gummy enough that coolant may be needed as a lubricant when a ball-nose or other round-profile tool is used. That was the case with this Stavax 420 stainless steel mold core. When dry milling wasn't producing an acceptable surface finish, the operator switched to using liquid coolant and the finish improved.
