· Figure 2: Rod Mill Ball Mills Description Ball mills are similar in concept to the rod mill but are charged with steel balls in place of the rods. The mill consists of a cylindrical drum, sometimes tapered at one end, and usually has a charge of steel balls (up to 40% by volume) ranging in size up to 125mm for larger mills.

Ball Mill Principle. The ball mill machine is mainly composed of cylindrical cylinder, end cover, bearing and big gear ring. Cylinder: The cylinder is filled with a ball mill grinding media (steel balls or steel cylpebs) with a diameter of 25mm-150mm. The loading capacity is 25%-50% effective volume of the whole cylinder.

 · These ball mills are relatively small, bearing mounted on a steel frame. All ball mills are sold with motor, gears, steel liners and optional grinding media charge/load. Ball Mills or Rod Mills in a complete range of sizes up to 10′ diameter x 20′ long, offer features of operation and convertibility to meet your exact needs.

For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged. Pulp is usually 75% solid (crushed ore) and 25% water; pulp is also known as ' slurry '.
