Using Ball Mills to Extract Raw Gold from Ores
To perform its functions, the ball mill operates on the principle of impact and attrition. This principle entails that the balls are dropped from near the top of the shell in order to bring about size reduction impact. The major components of the ball mill include a shell that is hollow and is … See more

Ball Mill Circuit Classification System Efficiency
The circulating load ratio is an excellent subject for study of classification system performance because it has long been recognized as such an important factor in ball milling efficiency. Results from the classical work of Davis (1925) are shown in Figure 2. Note that an increase in circulating load ratio from 150 to 500 percent yielded an ...

Ball Mill
The mill liners are designed to lift the media as the mill rotates, so the comminution process in the first chamber is dominated by crushing. In the second chamber the ball diameters are of smaller diameter, between 60 and 15 mm. In this chamber the lining is typically a 'classifying lining' which sorts the media so that ball size reduces ...

How Mill Load/Charge is Estimated
Sag mills in the gold and copper operations would vary from 6%- 15% and are normally grate discharge types in most cases the densities of the slurry in the mill is over 65% and that goes for ball mills also. Off course you have a upper limit or the balls will "float" out. Higher densities allow better grind and increase residence time in the mill.

How Ball Mills Lifter Bar Affects Charge Motion
The action of lifter bars is best understood by following the motion of ball charge inside the mill. There are two well-known modes in which the ball charge moves inside the mill: cascading and cataracting. The cascading motion of ball charge forms a compressive zone inside the mill where particles may break under slow compression.
