Ball Mill Grinding Theory - Crushing Motion/Action

2017-4-28  Then, with a mill half full of balls, any particular ball will roll down the incline something less than twice per revolution of the mill. As the speed of the mill is slowly increased, the time required to bring the ball back to the top of the pile is diminished,

2016-11-18  There are a lot of misconceptions about what goes on in a ball mill. We know that a drum filled with heavy metal objects will grind powder when it is rotated, but how exactly does this happen? Some people think that the powder is pulverized against the sides of the drum as the media roll over top of it. Others believe the grinding media should drop down onto the powder grains from above, thus crushing it by impact. While there are "drop" mills that operate in this fashion, the use of high-impact methods are not recommended nor even necessary for effectively milling

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
