Proline Mining Equipment/Gold Dredges 2"
The new Proline 2" dredge has redefined the role of the small dredge. Our latest developments have resulted in a smaller, and more portable dredge, with increased suction power and features normally found only on larger dredges.
This dredge is now powered by our all new HP 100 pump, direct coupled to the new Honda 2.5 horse power 4-cycle engine. This combination is incredibly powerful, capable of producing well over 100 gallons per minute and twice the pressure of our previous pump.
The Honda is extremely quiet and smooth running, with nearly twice the fuel economy of the 2-cycle engines, and of course, it eliminates the need to calculate the gas and oil mixture ratios of 2-cycle engines. This engine is equipped with the ever popular low oil shutoff.
Our HP 100 pump is manufactured with the same quality and features found on our larger pumps. One unique feature of this pump is that it has been equipped with a second discharge port on the side of the pump, sometimes called a "flusher port." This port supplies water pressure to run a flusher nozzle for serious dredging.
Because we take the small dredges just as seriously as the larger ones, we want the small dredge to be able to clean out the same cracks and crevices that would otherwise be passed over. The Proline is currently the only 2" dredge with this feature.
The recovery system has been completely redesigned as well. Due to recent changes in the pump and jetting system on this dredge, the suction power has dramatically increased.
More powerful suction means that the water and dredged materials pass through the dredge with greater velocity than before, therefore the wave classifier and riffle profile had to be adjusted as well. The increase in water velocity, believe it or not, actually improved gold recovery.
This dredge uses Hungarian riffles, which are designed to develop a strong vortex or "eddy" when subjected to higher water speed. This dredge builds a stronger vortex behind the riffles to hold the values better, plus it doesn't have the tendency to load up on low grade material that other dredges have, leaving the riffles unshrouded to do their job more effectively.
We still use "Noma" matting in this dredge, but now it is used for the full length of the sluice box. This combined with our unique one-piece classifier and riffle design has resulted in a greatly simplified sluice box and easier cleanups.
As before, the pontoons are actually used as part of the frame, eliminating the need for a heavier conventional frame. A knockout rod is supplied for cleaning rock jams that occur at the power jet, and it actually stays on the dredge when not in use. It is always there when you need it.
Through these recent improvements we were able to shed a few pounds, while actually making the dredge stronger. If you are planning on purchasing a small dredge, we suggest that you compare our features and quality with every other dredge on the market. We strongly feel that no other 2" dredge compares.
