![]() We've always used the finest cross-link polyethylene plastic in our floatation. The result of this design is greater dredge vacuum, less horse power required for operation, fewer rock jams, and improved fine gold recovery. In addition, the configuration of the flare dredge allows the sluice box to sit much closer to the water, improving power and efficiency. ![]() The flare's rapid expansion causes all dredged material to slow down and begin to spread out before reaching the sluice box for improved particle distribution. There are several advantages that come from this design. The flare dredges are easily distinguished from the dredges that use a hopper, or "header box", in that they incorporate a large expansion chamber or "flare" which is located between the dredge's power jet and the sluice box. It was with all of those criteria in mind that we developed our line of dredges, most of which have seen many recent improvements. At Proline we understand the importance of performance, as well as reliability, serviceability, weight, appearance, and cost. Many years of research and development, along with decades of invaluable dredging experience, have gone into the dredges we build today. VORTEX removal rates are ACTUAL removal rates as seen with actual material moved using Magnetite black iron sand and rocks weighing 2.375kg per liter as to the sample product.We Understand the Importance Of Performance, reliability and cost VORTEX performance figures DO NOT have a small print clause with an Asterix symbol next to figures which would represent "best case Scenario" removal rates as opposed to actual removal rates. ![]() ![]() ![]() Suction does the work and water flow continues the work done. Once the hose is clear then water flow takes over. Powerful, simple, effective.Įxample: Getting a "RIDICULOUSLY THICK MILKSHAKE" ® ™ to move through a straw is similar to dredging a very sticky seabed and suction is key because if you drive a suction hose deep into sticky mud the water flow in the suction hose will often stall and the hose is essentially filled with a 'plug' of mud and only high suction will clear the hose. Vortex dredges have been designed to combine high suction values and high water volumes to tear up sticky soils with very high suction then keep it flowing with high water volume. ![]()
