Ball mill is an efficient tool for fine powder grinding. The Ball Mill is used to grind many kinds of mine and other materials, or to select the mine. Ball mill is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry way and the wet way. It can be divided into tabular type and

### Rod mills, how they function - mine-engineer

Rod 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.

### Mill (grinding) - Wikipedia

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
