I'm curious about anyone who has experience with LARGE tumbling
operations.

We have a large volume (perhaps up to several tons a day) of oblong
ceramic balls that we would like to make more round. Yes, no metal is
involved but I've heard more about tumble polishing with ball bearings
and things rather than ceramics.

Would tumbling with, say, SiC or other abrasive particles accomplish
this reasonably efficiently. Is there a better process for very large
volumes?

Any good books or sources on the principals of tumbling that i should
read?

thanks
