Is the dredge powered by a powerjet or suction nozzle? If powerjet is it single or twin jets?ĭoes the dredge have a flare, or crash box or just straight into the sluice?Īpprox how high is the head of the box above the water when it is running? New users can’t put up more than 1 photo sorry.Ī couple of really important questions first. If any one has some suggestions or input that will help that would be great. It wouldnt take much to lift the box and engine. Pros of the unit is the portability and width, can break down and carry into tight gorges…Ĭlassification is probably the most urgent, with a longer and heavier dampening mat, in future will re engineer a wider box. If I run it over 3/4 throttle I am concerned the light flood gold will float away. When things open up again, I want to set up a classifying mesh or punch plate in the box, this will have a wave at the start to deflect any jetting due to blocked up suction hose.ĭoes anyone have experience with gold hog Matt’s or dream Matt in a dredge? I guess they would reduce the concentrates but imagine the rocks rolling would unsettle the bed holding the gold. Would periodically stopping dredging and running full throttle to clear the suction hose upset the sluice bed if not picking up gravel? I put a grate on the nozzle to reduce the size of rock going through and blockages but it just means less production and more arm and hand work. Improvements, I am looking at or have done. I tend to have better recovery with my hand sluice box. It has about 100mm deep of water when running going through the box and the end of the box is submerged… the force of water going out seems to not cause any back pressure. It runs riffles and collects lots of rocks etc. It’s got a 5 inch suction pipe on it which is probably over sized for the pump. Problems, tends to block up the pipe unless running at 3/4 or above, resulting in jetting out over the box.
