I know it sounds counterintuitive, but if the grizzly bars are inverted, they don't wedge full of rock. The issue with them being like they are is they funnel the rock down so it wedges in the slot. If you close in the open side of the angle, and put them with the flat side up, you'll find the rock won't wedge in as bad.
Don't have any pics. Sprocket and chain dive, just a simple setup. I'm not going to post any pics or videos on his set-up. Because I don't think Econo Screen wants that posted. I still buy metal and parts from them.
I screen composted of leaves and wood. Have to bump it slow. I also screen large to small rocks with sand mix. Give me a sandy loom. The bucket is 7' x 2' x 2'. I average about 25 to 50 seconds a bucket.
