A spiral separator used in mineral processing. Concentrate is fed from along with a constant flow of water. Through centrifugal forces, the lighter (waste) material is flung outwards and pumped into holding or waste dams, while the heavier mineral rich ore accumulated towards the inner of the spiral.

The De Hoxar Spiral Separator is a novel, compact gravity settlement device comprising a spiral plate pack within a tall circular settlement tank. The plate pack rotates continuously in conformity with rising speed of wastewater and capture settling particles on the plate efficiently. Having a small footprint and low operating costs, the ...

Spiral separators, or spirals for short, are a versatile method of gravity separation that can deal with a comparatively wide size range. Separation is achieved as a result of centrifugal forces induced by slurry running down the spiral, which forces lighter minerals to the outer bend whilst heavier minerals stay closer to the central axis of the spiral.

It can be seen from Table 1 that researchers are more inclined to use the Euler-Euler model based on CFD in the particulate flow simulation of spiral separators. The Euler-Euler model treats granular flows as continuous fluid flows and generally uses the kinetic theory of granular flow (KTGF) model to describe the granular interactions, which …

Spiral separators, also known as spiral sorters and rotary sorters, have a vertical spiral that is either fixed or can be rotated. They are used to separate free flowing round …

As flowing film gravity concentrators, spiral separators are extensively used in the processing of numerous minerals. Appropriate design of their cross-sectional geometries has been known as an effective method to improve the performance of spiral separators. However, limited work has been published on the impact of cross-sectional …

The design parameters of spiral separators can be classi fi ed into: trough dimensions, added features, ancillary equipment and manufacturing method / construction materials. …

The experimental results show that the spiral separator is efficient to remove ash and enriched carbonaceous components in coal gasification fine slag by separating feed () into concentrate (81.2%), middlings (8.8%), and tailings (10.08%), where the ash content in tailings is up to 90%, accounting for 18.5% of total ash in feeding.

Spiral separators have undergone continuous development over the past 40 years. The focus of some more recent developments has been towards the processing of progressively finer mineral particles ...

It is possible to deliver the spiral separators with 2 or 3 outlets, depending on the seeds you have to separate. The standard model has 2 outlets at 180 angle. By using the insert set of brushes the extra outlet (third outlet) in the outer spiral for an extra separation of the "swug-out seeds" is not required any more for the majority of seeds.

In comparison, rotary sorters are in a way an improvement from spiral separators. Rotary sorters work best if you want flexibility for fine, precise tuning using a VFD Drive. They need power to operate, but they reduce a lot of load off other machines. Sorters have rotating cores and precision technology to help filter out broken or misshapen ...

A spiral-wound, nonporous cellulose acetate membrane separator is used to separate a gas containing H2, CH4, and C2H6. The permeate is 95 mol% pure H2 and contains no ethane. The relative split ratio (separation factor, SP) for H2 relative to methane is 47. Using the fol- lowing data and an infinite surroundings temperature of 800F, compute the ...
