Bin to hopper by auger question

PostBy: k9 Bara On: Thu Aug 30, 2012 4:51 pm

Thank you to those that posted pictures and comments on your auger setup's. They helped me in completing mine. :up:

This setup is working great, but I would like to slow the speed of the motor. Is there any reason why a rheostat can't be used to slow it? The motor is a 1/2 hp Marathon from tractor supply. I just have it wired to a standard light switch, for now.

Rheostat, sorry, no, not that simple.

Is your marathon 1/2 hp motor @ 1725 rpm?

Figures, I should have known. Thank you for the reply. Yes I think that is the RPM's of that motor.

Whats the rpm you are looking to get at the auger?
You would be better off changing the pulleys, that way you lose speed but gain torque if you cut the voltage with a reostat or variac transformer you will lose speed and torque.

That is a great point. Your right, I just wanted to slow it to reduce the wear on the auger.
I can live with it this way, just was wondering. What kind of life expectancy should i expect? i burn all year, and the auger setup wasn't cheap. Has anyone worn one out yet?

There are grain augers of my dads farm that have been there sense the 50s granted they mostly get used in fall/winter but they are no where near worn out.

You would have to change one or both of the pulleys.

Thank you all for the help, much appreciated. The links are very handy, Thanks. I'll measure them in the morning and see where I'm at now. It may be ok, but it seems to move a serious amount of coal quickly.

I guess my current speed is fine. With a 2" motor pulley and 8" auger pulley equals 440 RPM's. It sure moves some coal that's for sure. Thanks again for the links.

That is slightly faster than the EFM auger. :D

How small can a motor pulley for an auger motor go?

The comment that it is faster than the efm's, and certainly the AA's isn't pertinent because one slow speed auger is running to feed a burn pot, and the AA's have the hollow tube for overfill abatement. My auger fill the burn barrel in less than a minute, but only run once a day anyway. All anyone cares is to maintain the fuel supply. Trick question and answer session, huh? Look at the AHS ashing auger motor. About an 1.5" on the motor, 8" on the driven end. You can do whatever you want for diameters if it suits your purposes.... :idea:
