12 rpm, 110 lb torque motors... Brewing use?

[TXCrash]

Side story:
This week I've really been putting my degree to use and have been clearing out a semi-abandoned research facility. There have been more than a few things that have peaked my interest - either for scrap value, brewing use, or other purposing. In the next couple days, I'll be posting threads on a few of these things - getting a feel for their brewing suitability, and if there's interest they'll make their way to the classifieds section.

Item in question:
Dayton 120v, 1 phase gearmotor. Continuous duty, 12 rpm, 110lb torque (note the specs might be a tad off, I looked last night). I haven't verified that all of them work, but the one I tested ran quietly and strong.

I'm thinking: mash mixer? HLT mixer(don't need that much torque)? Super quiet (and slow) grain grinder?

I imagine if you wanted you could gear it to crush grain much faster.

Maybe to stir your mash tun?

Gear it up with belts and sheaves to increase the rpm to something reasonable. This would be the reverse of what is usually necessary for most high speed motors. Big sheave to small sheeve, maybe 12" to a 1.5" would do it.

Is that torque rating in in-lb or ft-lb?

110ft/lbs of torque would be a monster, anyway 12rpm is slow for a mash mixer, from my research optimum speed is around 30rpm. That speed is based on a compromise between thorough mixing, not beating up the husk and eliminating temperature stratification in the tun. Might be better suited for a grain mill.

I agree... However, the majority of us are using coolers with no stirring mechanism. You can do a grain mill with a drill.. I say be different and step up your efficiency! :rockin:

more than most compact cars

Understood. It has always bugged me, though, when people give the wrong units. Something I had drilled into me in freshman Physics, I guess...

If I'd been paying attention I would have stated the torque specifications properly. While these are a tad slow, they've got plenty of torque (yeah, yeah, in-lb) and are pretty darn quiet.

I have 10 of these, they'll make their way to the classifieds section in the next couple days. I want to make sure they all work and run em for a couple hours a piece before officially listing them.

Torque would go below acceptable limits if sped up to crush grain IMO. Mine is 100 in-lb
as it is @ 175 RPM.
