    A ball mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, There are many types of grinding media suitable for use in a ball mill, each material having its own specific properties and advantages. Either wet-grinding, or non-sparking media such as ceramic or lead must be selected. not react with the material being ground, to prevent oxidation or explosive reactions that could occur with ambient air inside the mill.
