The "Martin" Multi-Helix Spiral

Secondary Concentrator


The Multi-Helix Spiral has excellent recovery performance with both alluvial and milled hard-rock ores. It offers the perfect application for mercury recovery and tailings projects. Our equipment is also great for bulk sampling. It has the equal ability of a concentration table but is more practical and versatile. This enables the machine to separate gold, silver, platinum, and any precious metal or mineral that is in a free state.

Two Models:

16” Cleaner – 1 to 2 ton/hour
16” Finisher – Up to 1 ton/hour

Our machine is adaptable to any mine operations, replacing sluices and jigs. It runs on turbid water, which is perfect for recycle and settling ponds.

Two Models:

16” Primary Concentrator – up to 15 tons/hour
