Conical mills are made in a variety of shapes and sizes from tabletop lab models to robust, high- capacity and full-size machines which can be used in the processing of large quantities of materials. ... Ball mills and conventional milling equipment are both used to grind materials into smaller pieces. Ball bills can handle materials like ore ...

Construction of Ball Mill. The ball mill consists of a hollow metal cylinder mounted on a shaft and rotating about its horizontal axis. The cylinder can be made of metal, porcelain, or rubber. Inside the cylinder balls or pebbles are placed. The balls occupy between 30 and 50% of the volume of the cylinder. The diameter of the balls depends on ...

The main part of the ball mill mainly include feeding part, discharging part, a rotary part, a transmission part (reducer, small gear, motors, electrical control) and other parts. Hollow shaft adopts steel castings, the liner is detachable, slewing gear hobbing with casting, the cylinder body with wear-resistant liner, with good resistance to wear.
