The proven technology sorts different materials according to their density using the centrifugal flow. The lighter particles are thus flushed outward and the heavier particles inward. Our spirals are simple to install, are distinguished by their long service life and, as a static system with no moving parts, energy and maintenance costs are reduced to a minimum.
Multotec-designed spiral concentrators are used across the world in coal, gold, iron ore, mineral sands, platinum and chrome processing plants and other minerals.
We manufacture a wide range of spiral sizes and configurations that can be optimised to your application.
The benefits of the Multotec Spiral Concentrator:
Beneficiate material between 38 and 2000 um, depending on ore type
Available in single, double and triple starts
Spirals range between small diameter (+/- 560 mm) and large diameter (+/- 950 mm)
3 to 12 turn spirals as required by your application
High separation efficiency reduces the number of stages on a plant, reducing overall footprint
Sliding or auxiliary splitters can be used to achieve targeted grades and recoveries
Auto Reject Channel® offers excellent removal of unsuitable particles
Trough surfaces are sprayed with polyurethane to required thickness to improve the service life of the spirals
