[BProckets] Ceramic Milling Media Explosion: A Clarification?

[David Sleeter]

Doug said:

"There is at least one documented incident where ceramic media was used in a
ball mill (milling BP), that ball mill exploded.  It has been reported on
both the PML and the r-BP lists."

Dave Sleeter asks:

When Doug says that "ceramic media" caused an explosion in a BP mill, what
was this ceramic media made of? "Ceramic" is a generic term, and there are
MANY kinds of ceramic. For example, if the media that caused the explosion
was made of regular porcelain, that would be dangerous. But the media that I
get from Coors is NOT porcelain, and I'm not even sure it would qualify as a
true "ceramic". It is 90% aluminum oxide, which has vastly different
properties. As a matter of fact, it's VERY HEAVY, a fact which you notice
the moment you pick up a handful. Did the PML and r-BP posts about this
explosion clarify what the media was made of? If not, someone should try to
find out, because that information would be important and valuable.
