I think that this page should be merged with "Disk Mill". 'Disk' seems to be a more common spelling than 'Disc', so I put my entry in "Disk Mill".

'Disc Mill' has "about 19,000" hits on Google, compared with "about 737" for 'Disk Mill'. Although Wictionary and m-w.com both agree that 'disk' is the main spelling while 'disc' is the (mainly US) variant. -- MSchmahl 23:15, 16 January 2006 (UTC)

Another question, does copyright law still apply on very old patents? I found a good diagram of a disk mill on the patent office website from 1876. Would that be acceptable on wikipedia?

I'm pretty sure that this is now in the public domain. ike9898 21:54, 15 November 2006 (UTC)

[edit] Attrition mill

Is this the same thing as an attrition mill? I saw one website that claimed they mean the same thing, but I'm not sure. ike9898 21:54, 15 November 2006 (UTC)
