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.
