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 chargeOptimization of mill performance by using - SAIMM,As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, isBall Kibble, Ball Mill Charger. Diameter - AM King,A.M.

Optimum choice of the make-up ball sizes for maximum,

For the same amount of ball charge, the number of balls in the mill decreases as the ball size increases. Thus, the S values are lower for larger balls. However, larger balls are capable of breaking large particles; therefore, the size at which the S value becomes maximum, x m, increases as the ball size becomes larger.Used Ball Mills For Sale from Machinery and Equipment,Machinery and Equipment buys and sell Used Ball Mills for mining and minerals applications, as well as smaller batch mills for chemical applications.
