Mineral Spiral Concentrators, Model W6

Primary applications for these spirals is the recovery and concentration of minerals (high specific gravity material) from pulp streams (with low specific gravity material), which have at least 10% and as high as 90% high density minerals.


Feed to spiral, per start, is characterized in the ranges below:

Feed Capacity: 1.6 to 2.6 ton/hour
Pulp Density: 30-60% solids
Pulp Volume (max.): 22 GPM
Feed Particle Size Range: 0.03 – 2mm (10 mesh to 450 mesh)
Wash water consumption 2.2 GPM to 6.6 GPM (Up to 11 GPM in some applications)

Some features of this spiral are listed below:

Enhanced mineral separation due to wash water addition
Number of starts – single or twin
Number of turns – 5 or 7
Auxiliary con splitters are located every half turn, after the first turn, on each trough Auxiliary splitters may be blanked off with optional blank splitter inserts
Heavy Mineral Product is collected via the center column
Open wash-water supply channel for operator access and cleaning

Some applications are listed below:

Iron Ore Beneficiation
Mineral Sands Separation
