Need a 14 inch sprocket for trommel


Recommended Posts

Charles,

Another thing you may want to consider if you can't find the sprocket that you're looking for is welding the individual teeth directly to the trommel's barrel, I've seen a few trommels done this way.

This company may have what you need but you will have to contact them to inquire about the sprocket by clicking on the home link at the bottom.

You don,t state how many teeth you want on it nor for what size chain or if you want to use a V-belt.

I got mine from McMaster - Carr. You can look them up and fine most anything you want. I had to have

a machine shop cut the center out of mine to fit the drum I made, cost me $50.00 to have it done.

Then had a welder weld it on a stub of 8" pipe that I bolted onto the drum. Not finished with it yet.

Correct me if I'm wrong, but did you instal the coil inside the barrel?

I think I know how you did it, great idea! :wubu:

To make the coil , they just cut another section of the Pipe in a spiral strip to the width you need.

You may find the sprocket here but there pricey!

Yes I cut the coils and installed them to make a reverse helix, when finished there will be a screen

inside for the oversize ( 3/8" ). Oversize out the far end GOLD out the near end with no sluice to

clean out.

I think ya have a heck of a good plan! :brows:

What slope will ya start with? :hmmmmm:

Slope will be very shallow, just enough to keep the oversize moving

and any small stuff that is in the coils. This can be controlled with

the speed of the drive also. I can run it from 0 to WAY to fast but

think to start with it should be in the 8 to 12 RPM range.
