High
Energy Ball Milling
In discussions on high energy ball milling, the more generic
term "ball mills" is often used in place of the terms
"stirred ball mills" or "Attritors," but
the differences between the types of mills are quite distinct.
And, depending on your application, you may find
that one type of high energy ball milling is more appropriate
for your operation than another.
In comparison with conventional ball mills, Attritors use fewer resources, including:
- Time, Energy, Media
- Plant Space
In addition, Attritors offer the advantage of
being able to take samples at any time and making formulation
adjustments during high energy ball milling. Alternatively,
ball mills are closed systems and do not offer these advantages.
Nevertheless, ball mills can be a more appropriate choice for
grinding larger sized material starting at 1/4 " or larger.
It should be noted that ball mills are much larger than Attritors
and therefore require a special foundation.
The Attritor's design accounts for much of the
difference: conventional ball mills turn the entire drum or
tank containing the media and the material, while Attritors
stir the media in a stationary tank with a shaft and attached
arms or discs resulting in a more efficient use of energy for
the milling process. Further, Attritor tanks are all jacketed
which allows for more precise temperature control during high
energy ball milling.
The savings in energy and the increase in grinding
efficiency provided by Attritors are substantial. The graph
below compares various mills during the high energy ball milling
process.
