Proline Understand the Importance Of Performance, reliability and cost
Many years of research and development, along with decades of invaluable dredging experience, have gone into the dredges they build .

All Proline dredges are "flare" dredges. 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.

There are several advantages that come from this design. 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. In addition, the configuration of the flare dredge allows the sluice box to sit much closer to the water, improving power and efficiency.

The result of this design is greater dredge vacuum, less horse power required for operation, fewer rock jams, and improved fine gold recovery. We've always used the finest cross-link polyethylene plastic in Proline’s floatation. It has proven to be one of the toughest materials available, as it is very UV resistant and maintains its pliability much longer than some other types of plastic currently being used.

All Proline pontoons have stainless steel threaded inserts cast into them which makes for easy assembly and maximum strength.
The recovery systems in Proline’s dredges are always under constant development. Although the changes are not always apparent, their results have been rewarding. Critical attention has been directed at riffle profile, riffle timing, and classifier design.

Proline’s highly acclaimed "wave" classifier is unique in that it creates a pulsing or "jigging" action similar to that which is found in many large mining operations. This allows the heavier values to settle out much sooner, while at the same time working the lighter material out of the sluice box, constantly enriching the concentrate.

Proline’s system not only provides impressive, consistent fine gold recovery, but is much lighter and easier to work with than the cumbersome "triple-sluice" and "multi-stage" designs offered by others. All of Proline’s dredges are equipped with "Nomad" matting for the entire length of the sluice box.
One major problem associated with all gold dredges over the years has been the far too frequent rock jams in the dredge hose, particularly at the power jet. On conventional dredge designs, the steel power jet slips inside the hose, creating a restriction and many plugs in the process. All 3" and larger Proline dredges utilize Proline’s exclusive "sure-flow" hose coupler system to essentially eliminate all surface rock jams. This system, when coupled to Proline’s unique oversized jet-flare assembly not only prevents a lot of downtime clearing the dredge hose, but will generally outlast conventional steel power jets by 400% or more. We pioneered the original non-clogging jet many years ago, and although it's been imitated many times, it's still the most efficient, simplest design on the market today.

Buying a gold dredge isn't something most people do every day, so it pays to do some research before making a purchase.

Outstanding dredge vacuum and long life


Proline manufacture one of the most comprehensive series of pumps in the small dredge industry today. These are high performance centrifugal pumps designed specifically for operating our dredges and dual-purpose machines. First, they are cast in the US from high quality aluminum then heat treated to a "T-6" hardness for years of service.

 

Each part is then machined on computer controlled equipment to maintain the exact tolerances required for optimum performance. Proline's pumps are 5-vane and 6-vane "aggressive bite" impellers with large intake throats to provide high volume with working pressure greater than normally found on pumps of this type. They are hand-assembled using US made seals and grade 8 hardware.

 

The quality and performance of these units, when coupled with our efficient jetting systems, offers outstanding dredge vacuum, very little required service, and long life.
