Check priceSep 04, 2018 · A ball mill is a grinding device that is used to turn material into fine powder. Ball mills are cylindrical in shape, and are often the grinder of choice when it comes to mashing paints, ores, ceramic materials, and certain hard chemicals. By rotating on a horizontal axis, a ball mill can effectively convert a hard material into a loose powder.

Check priceRod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.

Check priceBall mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other.
