Hydraulic Concentrators

A “hydraulic concentrator” also called a “high banker” is a highly portable sluicing device that contains all the best mentioned attributes up to now. These units have classification screens that are designed to keep the larger material out of the sluice. But they also classify quickly enough so as to keep one or two people busy shoveling at a production speed.

The manufacturers of the model assure that their water pump unit will pump water to the concentrator at a distance of 200 feet away from the source of water, allowing much more operational mobility.

The concentrator is designed for the flux of water to pass through the sluice to be adjustable, and get the best recovery possible. A hydraulic concentrator is easy to build in comparison to having to relocate the sluice so that it works properly with the flux of water of a creek.

A typical high-banker could handle about a cubic yard of material from the creek bed in an hour, which equals a medium-sized sluice box built under optimum conditions. The hydraulic concentrator is not so heavy, only about 50 to 75 net pounds (depending on the size) including a pump engine. It can be successfully used as a sampling tool when larger quantities of samples are required from the areas that are not far away from the path. A hydraulic concentrator can also be used as production machine with excellent results. For this reason and the rest of factors previously mentioned is probably the best and most popular medium-sized portable gear among all the sluicing-on-surface equipment in the market.
