No Dust Then?
You should read 'Mineral Processing Technology by Wills et al.'
That will give you a grounding in the basics of comminution and sizing.
Failure to mention the product quantities in the first place indicates that Wills or similar should be read and understood.
Also read 'Foundations (any issue) by Martin Engineering' which will give insight into dust generation and levels.
Then, when you know what is involved you can ask again.
