BLUE BOWL CONCENTRATOR KIT
Concentrator kit includes the blue bowl, 750 gallon per hour 12 volt pump, 3 feet of 3/4 inch flex hose, pair of battery clips, and instructions (Leg Levelers sold separately $22.95).
The blue bowl gold concentrator is completely portable and will quickly remove your fine gold from your concentrates. It is designed to work forever, with no moving parts to wear out or break. Pre-screen your concentrates to at least 30-mesh using a classifier before adding to your blue bowl.
To recover micro-fines, prescreen the concentrates using a 50 or 100 mesh classifier
Panning fine gold concentrates by hand is difficult and tedious. The blue bowl can recover gold as fine as talcum powder.
