A 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.
Ball mill is a horizontal machine, contains a hollow cylindrical shell that rotates around its axis, Inside the cylinder, there are many different sized stainless steel balls. As the the cylinder rotates, the mill balls lifts and then drops, strikes the materials, that is the impact and attrition take place.
