Ball Mill Overview. Ball mill is crucial equipment for grinding after materials are crushed. It is an efficient tool for grinding various materials into powder. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.
Ball mills Solid, reliable and durable. Ball mills are the classic grinding plants: Around the world they are the most common installations. Ball mills convince thanks to their simple principle and low maintenance needs: They are robust, durable and extremely reliable in operation. By using ball mills in closed circuit with a separator, their efficiency can be increased even further.
A ball mill is a cylinder partially filled with a grinding medium, like small stainless steel balls. When rotated on its axis, the material that fills the rest of the cylinder is crushed. Hammermills instead use hammers to crush material. Jaw crushers, in comparison, crush material between two plates.
