$25 is cheap, you got a bargain.
This is the heavy duty grey stuff that you can transfer liquified gravel through with the steel winding inside of it.
Usually worth about $15 a meter, all sold now anyway plenty of people on gumtree loved it and ran for it at that price.
The only other way I can think of making sure the tailings pile is clean is to have a jet firing up from the arse end of the hopper with a shit load of water to wash it all and Tumble it as it comes back down the screen.
That is, instead of the spray bar setup.
Hey mate, so initial testing to stop the clogging by introducing a perforated screen across the length of the hopper showed that the material on the screen was not getting washed properly by the spray bars by the time it fell off the back of the hopper into the railings pile it was still dirty...

I didn't end up going due to hangover and injury but my digging partner did so test results will be back in today once he's back into reception.
Cheers for that mate, I believe what I am going to do is run some alloy angle around the inner perimeter of the hopper and drop a piece of perforated sheet on top all the way down so that only really small stuff can make it down in through the Grizzlies. Do you think this could work? And that...
Hey everyone should this be just flat bottom under the Grizzlies? I've found it clogs up once larger material falls through the Grizzlies... And read the bottom should be bare so that the water makes things flow
