Gravity Spiral Concentrator Working Principle

Spiral Concentrator Spiral concentrators are modem high capacity low cost units developed for the concentration of low grade ores Spirals consist of a single or double helical sluice wrapped around a central support with a wash water channel and a series of concentrate takeoff ports placed at regular intervals along the spiral Figure 17

Spiral Concentrator Outotec

In a spiral heavy mineral concentrate is selectively directed into the spiral trough near the inside of the spiral surface through the use of adjustable product splitters The concentrate then flows through product discharge outlet ports down the length of the helix

Spiral Concentrator Multotec

As the mineral stream is fed from the top of the spiral a combination of forces act on particles as they move down the trough of the spiral circuit These forces include gravitational forces centrifugal force hydrodynamic drag and lift and friction forces
