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.
Cutting steel bar, rod, and tube is most affordably done using an angle grinder and cut off wheel. Making nearly straight cuts on flat bar with a cut-off wheel can be acheived by rotating the guard on the grinder, and positioning cut off wheel straight down perpendicular to the bar. This method can be imprecise and lead to more grinding work later.
