Basic Principles:

The riffle frame is an alternative to the standard frame which comes with the Goldblitz sluices, but also fits to some sluices of our market followers and, of course, self made sluices. This frame needs, compared to the standard frame, more water but supplies you with three large vortices, catching flitters out of the stream and a larger deposit volume behind the three riffles. If the expected flitter size is >5mm, this frame is the first choice!

Description:

This section describes the features of the riffle frame, especially in comparison to the first version!

• New distribution of riffels throughout the length of the frame. Compared to the version 1, this frame has larger gaps between the riffels. On one hand, this slows down the speed of the water on the other hand it generates larger vortices in a speedy water environment. For slower flows, there is almost no difference.
• New tear-off edge. The edge of the riffles was redesigned and changed from an flat line to a radius shaped curve. The idea behind it is, that by doing so, the vortices gets slightly distorted towards the left and right boundaries of the sluice, pushing the material slightly back to the middle of the inside current. The vortices in the middle are smaller, at the boundaries they are bigger and slower so this should generate a sucktion towards the middle.
• Optimized slots and gaps. We increades the production accuracy reducing all gaps and spaces. We improves the position and size of the wholes for the rivets, improving the overall clamping behaviour of the frame.
• Optimizing dimensions. Together with our laser cutting center, we optimized the production of the frame, improving the sizes to avoid jammings while mounting the frame. The overall tolerances are increased.
• Sealing. Like the version 1, the new frame has two skimmer to avoid gold from gliding along the frame. These skimmers are sealed with our outdoor silicone.
• New Technology - same price.
