Blue Bowl Concentrator

The Blue Bowl Concentrator will quickly recover your fine gold with only the water from a garden hose, or it can be rigged to recirculate with a 12 volt pump and a 5 gallon bucket. This is the famous blue plastic bowl designed to work forever with no moving parts. Comes with water flow control valve.

Water is pumped into the bowl and drains through a tower in the center. Lighter material spirals around the Bowl,up the side of the tower and out the hole in the middle. Heavier gold sits on the bottom or at the base of the tower.
