D.A.M. Concentrator Blue Bowl

The D.A.M. (Desert Automation Mining) Concentrator Blue Bowl is the original and still the best spiral concentrator for fine gold recovery. With no moving parts to wear out, this elegantly simple device will last forever with basic care.

The Blue Bowl works on a simple principle: water spirals up from the center, creating a flow pattern that separates materials by density. Gold, being heavy, settles to the center while lighter black sand and other materials wash over the rim.

What makes the D.A.M. version special is the precision engineering. The spiral pattern and water flow dynamics have been optimized through years of refinement. Combined with the included flow control valve and leg levelers, you have complete control over the separation process.
