I have watched a lot of these vids and this is the worst designed chute I have seen. The mouth, both ways, are WAY too small for the size rocks they are feeding. They need to realign the entire chute and mouth. And one thing I can't figure out that none of these have on any operation, why are there no horizontal bars on the top part of the moving plate? That part that is smooth above the vertical bars should be horizontal bars so they can force the rocks down into the chute. When they get stuck, they just rub the smooth part. If they were horizontal bars (like the vertical ones on the moving plate), this would help break up the larger rocks as they go into the chute.
