Mar 04, 2019 · Riffle Shapes And Design Sloped Flat Bar Riffles. In general, flat bar riffles at virtually any slope failed to generate efficient concentration vortexes and seemed to operate basically as dams to interrupt and slow the water flow just enough so that the normal gravity settling characteristics of the various particles came into play. As a result capture of heavy materials was primarily based ...

» The Size of Riffles

Most recovery systems on suction dredges use fixed riffles to trap gold out of lighter streambed materials as they are washed through a sluice box by a flow of water. Riffles are baffle-like obstructions, fixed in place along the bottom of the sluice box. They are designed and positioned so that there is a back-pressure created that sucks water and material behind the riffles from the flow ...

Riffles and Sluice Boxes - How do they work?

As the flow passes over a riffle, the heavies will fall to the bottom behind a riffle. Second, the riffles are spaced a couple of inches apart, and act as a series of small dams, stopping the creep of the heavy material down the sluice. Without them, there would be a slow, but sure creep of gold out the end of the sluice.

SLUICE BOXES 101 | RECOVER MORE GOLD WITH MY GOLD

Early sluice boxes were nothing more than wood or fine clay troughs. Many different types of riffles were tried, stone, logs, grass, sticks, etc. The pioneer prospectors found that a rough wooden sluice with raised wooden slats worked best and was easy to build. The principal behind the sluice box is the same no matter what design is used.

Plans To Build Your Own Homemade Dry Washer

The design on a water sluice box is that the gold is retained downstream of the riffle. On a dry washer, the gold is designed to be held on the upstream side of the riffle. The riffle tray is one of the things that really need to be put together by welding. I suppose small bolts would be a possibility, but welding would be much superior.

Jan 07, 2009 · Poor riffle design and riffles are poorly sealed against gold migrating to one end and going under and around the riffles while following the sluice side. The method of vibration rotating parallel to the sluice induces a rotational vibration that forces heavies to one side of the sluice where it piles up and starts to walk over the riffles.
