Blue Bowl Concentrator Kit — Gold Recovery System with 750 GPH Pump, Leg Levelers & Display Vial

The Blue Bowl Concentrator Kit is a compact, no-moving-parts system that quickly concentrates and recovers extremely fine gold down to talcum-powder size.

Designed for prospectors and hobby miners who want a reliable, portable way to extract micro-fine gold from concentrates, this kit packages the Blue Bowl concentrator with everything needed for immediate field use. Built from durable materials and weighing about 5 lb, the kit pairs the precision bowl with a 750 GPH 12V pump, flexible hose, battery clips, adjustable leg levelers sized for a 5-gallon bucket, a display vial, and clear setup instructions.

How does the Blue Bowl separate fine gold from black sand and concentrates?

The Blue Bowl uses water flow and centrifugal action within its shaped chamber to stratify heavier gold particles toward the rim while lighter material moves toward the center drain. With careful feed rates and bowl angle, you can isolate micro-fines that are difficult to capture by hand panning.

• Operate with a 750 GPH 12V pump for consistent water flow.
• Prescreen to 30 mesh for general concentrates; use 50–100 mesh to target micro-fines.
• No moving parts means consistent separation and minimal maintenance.

What comes in the kit and how do I set it up in the field?

The kit arrives ready to run: Blue Bowl, three leg levelers sized for a 5-gallon bucket, a 1/4 oz plastic display vial, 3' of 3/4" flex hose, battery clips, and step-by-step instructions. Assembly is straightforward and portable — clamp the pump to a battery, attach the hose, mount the bowl on the leg levelers over a bucket, and adjust the bowl angle for optimal flow.

• 750 GPH 12V pump provides required flow and is battery-powered for remote use.
• Leg levelers adapt the bowl for stable mounting on a standard 5-gallon bucket.
• Includes a clear vial for collecting and displaying recovered gold.

How fine of gold can this concentrator recover, and what prep improves results?

When used correctly the Blue Bowl can recover extremely fine gold—down to very fine dust-like particles. Results improve when you prescreen concentrates: 30 mesh for general recovery, and 50 or 100 mesh when targeting microscopic flakes and flour gold.

• Recover gold as fine as talcum-powder with proper feed and flow control.
• Prescreening reduces heavy black sand load and increases recovery rates.
• Adjust feed rate and bowl tilt to tune recovery for different material sizes.

How durable and maintenance-free is the system for regular use?

The Blue Bowl is built for longevity—no internal moving parts means fewer wear points and easy cleaning between runs. Routine care is simple: flush the bowl and hose after each session, check hose clamps and battery clip connections, and store components dry to extend service life.

• Rugged construction designed for repeated field use.
• Simple maintenance: rinse, inspect, and dry—no lubrication needed.
• Lightweight ~5 lb kit makes transport and setup fast for weekend outings.

Who is this for: The Blue Bowl Concentrator Kit is ideal for recreational prospectors, small-scale miners, and anyone focused on recovering fine and micro-fine gold without complex machinery. If you regularly work concentrates, want a portable, battery-powered solution, and need a low-maintenance device that captures very small gold particles, this kit gives you the pump, fittings, mounting hardware, and instructions to start concentrating quickly.
