    New project! Building a 6" trommel and have some questions......

    My friend Sal and I are each building 6" trommels to replace our highbanker classifiers. So far he's started his build using an old gas bbq as the base framework. I'm going to try something different and more compact. I've got the plan in my head and on paper so we'll see.

    My question is, how much angle is best to start with for the 36" overall length long trommel tube with 12" of screen in the middle?
    I'll test it, but having a starting point will make it easier to design the adjustable angle tube frame. Maybe 1-3"?

    All my stuff ends up somewhere between 7-10 degrees it seems. Make it adjustable and experiment. BTW, 6 inches is pretty small to process any volume.

    Yeah, 6" won't do mass production but I don't/can't dig as fast as I'd like. 55, over weight and out of shape puts a limit on me.
    I'd love to go 8" but that size pvc or abs pipe is very hard or expensive to find. I may consider using corrugated drain pipe but that adds more weight and bulk. If 6" doesn't work out, I can always upsize later.


    I've watched several youtube videos of 6" trommels in use and they seem to be able to run a fair amount of material for the size.

    That's the fun of building your own stuff, adding to the pile of failures in the corner of my garage.
