PROLINE DREDGES

All of the Proline dredges are "flair" dredges. The flair dredges are easily distinguished from the dredges that use a hopper, in that they incorporate a large expansion chamber or "flair," which is located between the dredge’s power jet and the sluice box.  There are several advantages that come from this design, including greater suction power, less horsepower required for operation, fewer rock jams, and improved recovery of finer gold particles.

 

    Many hours of classifier testing eventually led to the design now found in all Proline flair dredges.  Proline’s highly acclaimed "wave" classifier is unique in

    All 3" and larger Proline dredges utilize their exclusive "sure flow" coupler to essentially eliminate all surface rock jams. This system not only eliminates much downtime clearing the hose, but will generally outlast conventional steel power jets by 400% or more.

    Finally, a word about the construction of Proline equipment.  The aircraft grade aluminum is completely TIG welded, as is all of the steel components for maximum strength.  Click on the links at the top of the page to continue to our dredges.

 

 

 

 

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 concentrates.  Proline’s system not only provides the highest gold recovery, but is much lighter and easier to work with than the cumbersome triple sluice and multi-stage designs offered by others.  

     One major problem associated with all gold dredges over the years has been the far too frequent rock jams in the dredging 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.
