     · 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
