G'day Kiwi JW,Yaeh I think the best angle for the face of the riffles is 45' . This morning I whent down to my shop [ formerlly a garage] and gave some boxes a look over,there doesn't seem to be any "formula" for the size / spacing of the riffles . other
A sluice box should be set with a 48 degree angle. Another rule of thumb is that the sluice should be angled to drop roughly 2 inches per foot of length. The exact angle depends

2. Reduce The Length of Your Cast. Fly fishers are notorious for thinking they can cast a fly the length of a football field and hit a bullseye the size of a dime on the opposite goal line. And while I’ve seen some amazingly accomplished casters who actually can, most of us aren’t that good.
The turbulence associated with the movement of a 4.5inch rock is a lot, compared to the mild state of suspension necessary to allow a finesized particle of gold to settle behind a short riffle. Since we must suck up rocks in dredging, the bigger rock we can suck up, the fewer we have to move out of the way by hand.
Sluice boxes process material best when receiving it from a steady feed. Too much material dumped at once into a sluice box has a tendency to overload the riffles and choke off the concentratingaction behind the
For best results, the angleiron riffles are 1inch. high with a ½ to 1inch wide lip, tilted 15° upstream, and. spaced 2 inches apart. Each riffle set is slotted in the. sluicebox and pressed down on the Nomad TM matting. The riffle sets are secured by metal or wooden chocks.
This is my 4th riffle reconfiguration in this dredge. and larger magnetite that plugs up nearly all riffles. The other area this dredge operates in has even finer gold and the most fine black sands I have ever seen. Keep in mind this is a 5" dredge with a massive amount of water flowing through the box.
best angle for my riffles Top 10 Best Assault Rifles. the riffle is the catch.At a 4degree entry angle they found that bowlers could reliably strike at a rate of 9095% percent of the time when they got to the pocket between the 17.5 and 18.5 board. That's a slightly larger one board area. At a 6degree entry angle however the pocket expanded.
If you need the water deeper, decrease the angle or increase the water flow. Changing the angle of a sluice box changes the angle of riffles or the shapedbottom. This affects how it works. Increasing the sluice box angle or the flow of water or both, will increase the speed of the water. This gives gold less time go settle.
1. Place the sluice parallel in a shallow area that has a good flow of water. You do not want whitewater flowing through the sluice, as you will more than likely lose material due to the fast flow of water. 2. Ensure that the bottom of the sluice is angled slightly lower than the gate of the box.

The reason that riffles work is two fold. First, there is an eddy created behind each riffle, causing a temporary lull in the water flow. The material that is flowing is in a liquid state. This causes the heavies to be at the very bottom of the flow. As the flow passes over a riffle, the heavies will fall to the bottom behind a riffle.
Here is a sure fire way to tell where your angle belongs. First off, you will have to move any larger rock through your sluice. If you classify your material (getting out the big stuff), you may be able to use less flow or
If the angle in use is the angle from the wall to the support, the compression stress on the support will be the load divided by the cosine of the angle. At straight up and down, the angle is zero, and the cosine is 1, so the force is equal to the load.

I have 5 highbankers, from small to quite large, like Wal, mine are configured exactly like my old dredges. The largest of them has 2 interchangeable riffles, expanded metal for very fine gold and standard lazy L riffles for coarser, although I tend to run it most of the time with the standard riffles, even at Oallen.
The Vortex Drop Riffle sluice system has a operating angle range of 5 to 15 degrees. The water volume is determined by the width and operating angle of the system. The setup angle and water volume will determine the water speed. The water speed is the most important factor when operating the sluice system. The steeper the angle the less water
