JCrewPyros Posted April 9, 2008 Share Posted April 9, 2008 Alright I am lining everything out to build a ball mill. I was wondering if I can get some information on motors. I will be tumbling a Lortone Q12 tumbler barrel. I have found a few motors on e-bay but I am not exactly sure what to get. I figure a 1/4 Hp motor with 1725 Rpm's is something about right. Like this one. 1/4 Hp Motor Would that be something that I need or can someone give me some ideas on something I could use say from a mom and pop store that would be in a small town in the states. Any information would be great. Link to comment Share on other sites More sharing options...
InRainbows Posted April 9, 2008 Share Posted April 9, 2008 That motor would be fine, I use a 1/3 hp with 1725 on my soon to come ball mill, except that it is ridiculously expensive. I bought my motor for 30~ with shipping. Also, some places have these hobby stores that sell mostly electrical stuff, I don't know much more about the, since I never saw one. Also, I saw that avatar on ytmnd. Link to comment Share on other sites More sharing options...
jacob Posted April 9, 2008 Share Posted April 9, 2008 That motor should work ok. or you could make friends with the person that works at/sneak into your local convenience site and get a washing machine for free, or failing that you could try a local junk/antique store if you have one, OR I could probably get you one from a junk store in my town for cheaper then ebay.PM me if you're interested.

JCrewPyros Posted April 9, 2008 Author Share Posted April 9, 2008 So can someone give me a picture of their tag on their motor so I have a visual reference to what I am looking for. That way I can ask around here in town at junkyards/repair shops. Link to comment Share on other sites More sharing options...
tentacles Posted April 9, 2008 Share Posted April 9, 2008 You're looking for a 1/4-1/2 HP 1PH (1 phase) 115V(100-130V) 1725RPM motor, "CONT DUTY". Link to comment Share on other sites More sharing options...

marks265 Posted April 10, 2008 Share Posted April 10, 2008 The motor on e-bay is TENV (Totally Enclosed Non Ventilated) which means dust proof which would be fine. A step up would be TEFC which is "Totally Enclosed Fan Cooled" which is still dust proof but uses an external fan for air circulation if heat build up may be a problem. And then if your pocket book is really fat I suppose you could find an explosion proof motor. Link to comment Share on other sites More sharing options...
JCrewPyros Posted April 10, 2008 Author Share Posted April 10, 2008 Thanks for the replys... I just called a place that sells em new... and uh no... 160bucks...

Bonny Posted April 10, 2008 Share Posted April 10, 2008 My ball mill is powered by barn exhaust fan motor. The RPM is 1075 and the HP is only 1/10 or 1/15 I think. It can mill 1kg batches of BP wihout any trouble.My only problem is that it needs external cooling. This is normally not a problem when used as a fan because it has airflow. I have a 120V computer type of fan that I blow on the motor for cooling. The mill has worked great for me for a few years now. Link to comment Share on other sites More sharing options...
JCrewPyros Posted April 10, 2008 Author Share Posted April 10, 2008 Alright... My leads are running low here peeps... I had someone try to sell me one for 70 Bucks... any ideas on something I can yank a motor out of that runs what was posted above? Link to comment Share on other sites More sharing options...
InRainbows Posted April 10, 2008 Share Posted April 10, 2008 It's a lazy day here, I took the honor of looking up "1725 rpm 1/3 hp" on eBay for you. It's looks older, but the seller says it works, why wouldn't it? http://cgi.ebay.com/GENERAL-ELECTRIC-1-3-H...1QQcmdZViewItem Now, here's another one that's new, but is more expensive than I would pay. http://cgi.ebay.com/NEW-ELECTRIC-FAN-MOTOR...1QQcmdZViewItem Link to comment Share on other sites More sharing options...

jacob Posted April 18, 2008 Share Posted April 18, 2008 Don't get that motor, no bearing on the shaft=major headaches. Link to comment Share on other sites More sharing options...
Swede Posted April 18, 2008 Share Posted April 18, 2008 How about a surplus-center GEARED motor, which then directly drives the power shaft of the mill? That would possibly save a lot of effort. You could very easily couple it on the cheap by using a short section of rubber tube, which you then hose clamp to the motor output and the ball-mill shaft. This would also take care of modest misalignments. Link to comment Share on other sites More sharing options...
JCrewPyros Posted April 18, 2008 Author Share Posted April 18, 2008 Well I ordered a motor... My fabricator roommate helped pick one out... I believe he can get this rolling...
